How to clean mold using vacuums and prevent it from growing again

Using HEPA Vacuum for Removal and Prevention of Mold

HEPA vacuuming removes mold spores and other allergens from the atmosphere hence reducing allergies caused by mold as well as preventing mold from growing.

About HEPA Filters

HEPA Vacuum Cleaner is different from other conventional vacuum cleaners because it comes integrated with high efficiency particulate air (HEPA) filter which filters out up to 99.7% of small particles, size 0.3 micrometers from the air. Mold spores are measured at between 1 and 20 micrometers meaning that HEPA vacuuming will rid your house of all mold spores as well as other allergy causing particles.
For conventional vacuum cleaners, mold spores, because they are small in size, will pass through the filter and through the exhaust back into the atmosphere. HEPA vacuum cleaners on the other hand captures all mold spores storing them in the vacuum for disposal and this makes it a good option for mold removal and prevention.

HEPA Vacuuming is the Remedy for other Allergies

Because of the HEPA vacuum filter, this equipment is also good for the removal of other allergy causing particles in the air. This includes pollen, dust mite, and feces.
A regular once-a-week HEPA vacuuming in your home is recommended. This not only removes mold allergens from the air thus reducing allergic reactions, it also creates an environment that is not conducive for the growth of mold.

HEPA Vacuums during Mold Remediation

HEPA vacuuming is as important during mold remediation as it is during regular vacuuming in the home. During the mold removal and remediation process, mold spores are bound to stir up in the air and settle on surfaces. This is why if the mold removal process is to be complete, HEPA vacuuming must be part of it as the last stage. This is because it gets rid of mold spores that have been stirred in the air plus those that have settled on surfaces after remediation.

Important Tips when Purchasing a HEPA Vacuum Cleaner

A good HEPA Vacuum cleaner will cost around $300. HEPA filters go with rating from H10 to H14 and this is determined by the percentage of microscopic particles that they trap. The higher the filter rating the more effective the filter will be at trapping particles and these ones, you can expect, are the more expensive.

Non-HEPA Filtered Vacuum Cleaners in Mold Removal

Conventional vacuum cleaners usually do not have the HEPA filter. Much as they are more common in homes, they do not remove mold spores and other micro particles in the air unless they are captured in dust which is what these vacuums are built to take care of. Non-HEPA vacuuming in fact stirs up mold spores and other fine allergens or if at all these will be trapped, they will only pass through the filter and back into the air. Take care not to run a non-HEPA vacuum cleaner on a patch of mold, as you will be exposing yourself to allergic reactions.

HEPA Vacuum Cleaners and Mycotoxins

Toxic mold produces mycotoxins which are quite unhealthy to human. Much as HEPA filters are effective at clearing micro particles from the air, they are not effective at removing mycotoxins in the air. Central vacuuming systems should be used instead of HEPA filters, in the removal of mycotoxins in the air. On the other hand, removing mycotoxins from surfaces like carpets can be difficult therefore, it is recommended that such a surface be replaced.

How to Remove Mold from Clothes and Fabrics

Excessive moisture in the house can lead to mould growing on clothes. Cotton and organic materials particularly, are more susceptible to mold and mildew.

Fabric Mold Removal Solutions

Totally getting rid of mold from clothes and fabric is not an easy task. Few solutions exist, that can be used to remove mold from clothes. Some examples are-

  • Vinegar
  • Baking soda
  • Borax
  • Bleach
  • Mold killing detergents

Guidelines for Removing Mold from Fabrics

Some important general guidelines will apply when it comes to removing mold from fabric. Firstly, use hot water when washing moldy clothes. Hot water does a great deal of killing mold and eliminating mold spores as compared to cold water. Before washing in hot water, it is good to confirm that hot water will not damage the cloth otherwise look for an alternative mold removal option.

If you have opted to use a mold killing solution, do a two-cycle wash then hang your clothes under direct sunlight. The sun’s heat and UV light help in killing mold. The sun is known to have a natural bleaching effect that is good for fading stains from mold.

Removing Mold from Clothes using Bleach

Bleach serves two purposes. Removing mold from clothes and fading away stains left by the mold.
First things first, bleach is not intended for all clothes. Therefore, you have to check your cloth-labels for warnings against bleaching. Again, just to be sure that bleach is the ideal option, perform a spot test with a little bleach and water on your clothes and confirm that they are neither discoloring nor fading.

For those with the challenge of mixing water and bleach in the correct proportion, an equally good alternative is bleaching detergents like Clorox and Oxiclean.

Guidelines for washing your clothes with bleach:

  1. Place your clothes in the washing machine and then add laundry detergent.
  2. Fill water and add a cupful of bleach or the recommended quantity as indicated on the clothes’ label.
  3. Run your machine the usual way.
  4. Remove your clothes at any stage when their colors begin to fade and rinse them thoroughly.


  1. Soak your clothes in a mixture of bleach and water in the ratio of a cup of bleach to a gallon of water.
  2. Give your clothes some hours in the mixture while making sure that their color is not fading.
  3. Wash your clothes normally in the washing machine using a laundry detergent.

Removing Mold from Clothes using Borax

Borax is a preferred mold killer because it is natural and non-toxic. You can use borax as a detergent by purchasing detergents with borax as an ingredient or you can use pure borax powder by mixing it with hot water. Hot water allows it to dissolve completely before you can use the mixture or washing.
Washing clothes Using Borax

  1. Place your clothes and some detergent in the washing machine
  2. Dissolve half cup of borax in hot water
  3. Add in the borax mixture once you have filled the washing machine
  4. Run your washing normally

Removing Mold from Clothes Using Vinegar

Vinegar is an effective mold killer that eliminates up to 82% of mold species. It is also very effective in eliminating moldy odor from your clothes.

Washing clothes using vinegar:

  1. Place your moldy clothes and some detergent in the washing machine and fill it with water
  2. Add in one or two cups of vinegar
  3. Continue with your washing as normal


  1. Add a cup of white vinegar into a bucket of water and allow your clothes to soak in this mixture for an hour or so.
  2. Once soaked, use laundry detergent and water to wash off both the mold and vinegar from your clothes.
  3. This process may be repeated until clothes are rid of all traces of mold and moldy odor.

Preventing Mold from Attacking Clothes

Mold comes with dampness, and for clothes to be attacked by mold it means they stayed in a damp heap for some days without being hung on the lines. One way of preventing mold is drying clothes either by hanging them on the lines or in a dryer as soon as they have been washed.

Secondly, sweaty or wet clothes after being worn should be stored in such a way that they are aerated. Stuffing such clothes in the laundry basket and waiting for when you will wash them is a sure way of inviting mold to grow on them. The same procedure applies to swim suites and sweaty shoes. In addition, towels should always be hung on the line after every use.

Wet clothes are not only susceptible to mold attacks but are also a major contribution of excessive humidity in the home. Finally, your clothes drier is not an exception. It also needs to be maintained to prevent mold room growing in it. Occasionally, take the dryer out in the open to aerate it or properly ventilate the room in which you operate it, to keep moisture in drying clothes from spreading to the rest of the rooms.

Signs and Effects of Mold on Clothes and Fabrics

The first sign that you have mold on your clothes is that you will itch when you wear them. Mold causes itchiness and redness resulting in a rash where it comes into contact with the skin. Secondly, due to the allergens present in mold, you will react by sneezing.

An effect that mold has on clothing is that it digests and eventually destroys the clothes. The larger the mold on your cloth, the greater the stain, and as well the more challenging it will be to remove the stains. Mold is also associated with bad odor in clothes.

Another effect that mold will have on clothes is that it will release mold spores in the home which promotes further growth of mold and allergic reactions such as sore eyes and sneezing.

Any time you notice mold on your clothes, it’s a cinch there are more clothes with mold. Sort all your clothes and remove mold from the affected ones as soon as is possible. Take time to aerate your home and clothes regularly.

How to Remove Mold on Drywall, Wood, Carpet, and Tiles

In the home, mold often occurs on a variety surfaces such as wood, drywall, tiles and grout, and the carpet. And there are different ways of removing mold from different surfaces. In this post we take a look at some of the most effective ways to remove mold from different places inside the house.

1. Mold from Drywall

Unpainted drywalls unfortunately are adversely affected by molds. This is because they are porous and so you may never have your wall exactly the way it was, even after mold remediation. In a worst case scenario, you may be forced to replace the mold infested drywall.

Removing mold from drywalls

For the sake of the aesthetics, mold on a drywall is better off removed and replaced. Use a blade to hollow out the moldy area, ensuring that the area falls between two blocks of wood secure at the back of the drywall.

Cut out a new drywall same as the moldy one you have removed, to fit it where you removed the other and join it to the wooden blocks using screws. To strengthen this joint, apply a joint or drywall compound. To achieve a precise fit, take your time to measure the dimensions of the cut out before replacing.

After allowing it enough time to dry out completely, sand the area you’ve applied the joint compound to give it a neat finish. Painting is recommended as it does not only give you a uniform finish, but also prevents the surface from future attacks by molds.
It is always advisable to HEPA vacuum the room after any mold removal process to get rid of any mold pores left in the atmosphere.

Here is a quick video on how to remove mold from drywalls

How to Remove Mold from a Painted Wall

Unlike drywalls, removing mold from painted walls is quite simple. This is because paint makes the wall non-porous hence, mold only grows on the surface and doesn’t penetrate.
Simply use a suitable solution to wipe or scrub off mold from the painted wall.

2. Mold on Wood

Unpainted wood is porous so it is likely that mold will penetrate wooden surface. However, once mold is remediated from wooden surfaces, it is safe to continue using the surface. Well treated wooden surfaces will not have mold growing on them in future as long as moisture levels are maintained at their minimum.
Painted wood is far much better than unpainted wood as mold will only attack its surface without penetrating.

Cleaning Mold off Wooden surfaces

A simple wiping or scrubbing using a soft cloth or an abrasive, along with clean water and detergent is enough to remove mold from wood.

A mold killer is ideal but would be optional at this point as the aim of this process is to get rid of mold from wooden surface. Again, you never miss mold spores in your home so you may want to focus on removing mold rather than killing mold. Killing mold is a good idea but we will not fail to mention that dead mold spores also cause allergic reactions.
You can use this same mold removal process on any wooden surface.

Cleaning Mold Stain from Wood

Cleaning off mold and getting rid of mold stains are two different tasks altogether. While the former will address the main issue, the latter takes care of the aesthetic value of your surface. Mold removal doesn’t necessarily mean that you are done with your surface. Sometimes there’s stain left by the mold. However, there is no cause for worry if you have removed the mold and reduce moisture content in the room to prevent mold from reappearing.

One way of removing stain from wood is by sanding it. The only challenge is that this method is not suitable for surfaces that mold had deeply penetrated. The other option is rub some bleach on the surface to fade the stain away. This method too is not given, as there is a possibility of bleach discoloring your surface. Better to perform a spot test to confirm that bleach is the best option you have for mold stain removal.

Get rid of the moldy Wood

Where cleaning mold off your wooden surface and removing its stain is not an option, you may want to consider replacing the moldy wood. This method is best applicable where it is easier and cheaper to replace the wood rather than remediate the mold on it. Otherwise, sometimes replacement is not worthwhile.

What Next after Remediating Mold on Wood

The importance of HEPA Vacuuming the room after mold remediation should never be overlooked. This takes care of the tiny mold spores left floating in the air to prevent further allergic reactions.
To keep your wood safe, you may consider coating it with paint or a fungicidal sealant to make in non-porous and to keep mold off the surface.

3. Mold on Carpet

Wall to wall carpets are easily attacked by mold compared to other carpets. If you notice constant mold growth on your wall to wall, you might be forced to remove it completely. This is because there is no guarantee of removing all molds off the carpet and leaving it on the floor only aggravates the problem.

Mold in carpet

Mold in carpet

Mold on Wet Carpet

A carpet that has been soaked in liquid takes time to dry. To make it worse, the padding at the bottom of the carpet takes an even longer time, sometimes beyond 48hrs, to dry. This makes it susceptible to mold.

Replacing Part of Carpet

Replacing a smaller moldy part of the wall to wall can be the better option provided you don’t mind the difference that the new section will bring. Ensure that as you are cutting this section out, you include a 12-inch allowance on each side.

To prevent the growth of mold on the new section you are going to fit in, allow the floor to dry completely before you do the fitting. The importance HEPA Vacuum after every mold remediation process can never be overemphasized.

Mold on Rugs and Non-Fixed Carpets

Unlike the permanent wall to wall carpets, rugs and non-fixed carpets are a lot easier to handle. It takes simple cleaning rather than replacement, to remove mold. For best mold remediation results, let a professional carpet cleaning company or mold remediation specialist, do the job.

For the DIY enthusiasts, all you need to do is take out the carpet, spread it on a flat surface, and sluice both sides. Thereafter, use a cleaning solution or mold killer to scrub out the mold. Finish off with a thorough rinse. Once this is done, you can achieve a quick dry with the help of a wet vacuum, otherwise give it ample time to dry well under the sun. Be sure to dry both sides of the carpet to prevent mold from growing back.

HEPA Vacuum the carpet or beat it up while on the line to get rid of any mold spores and other particles left after the entire process.

4. Mold on Tiles and Grout

As far as mold is concerned, tiles are not an exception. Tiles found in wet areas like in the bathroom and kitchen sink are more prone to mold compared to the others. However, tiles are non-porous therefore cleaning mold off them shouldn’t be a difficult task.

Removing Mold from Tiles and Grout

Using a brush along with detergent or mold killing solution, scrub off the mold from your tiles or grout. In addition, commercial grout and tile cleaners are available in the market today.
Mold stains are common on grout after mold has been removed. Bleach is a good solution you can use in fading the stain but take care to perform a spot test to be sure that it is suitable for this purpose. Wear gloves to protect your hands when using bleach.

Hydrogen peroxide also does a good job so you can use it as an alternative to chlorine bleach. Another option is Oxiclean containing oxygen bleach and this is good particularly if you have a septic system. Once you have applied bleach, allow some ten minutes.

Baking soda also works pretty well with stains on tiles and is a cheaper option too. Mix a little baking soda in water then scrub it on the grout using toothbrush. Repeat the process over and over until the stain is cleared.

Once the stain is cleared, rinse off the bleach with plenty of water to leave your surface clean and stain-free.

Sometimes, stubborn stains won’t clear as fast as you expect them to. In this case try soaking paper towels in bleach and placing them on the stained section of your grout. With time, the stain should fade away.

Grout Treatment

Applying grout sealer on your grout is a good way of clearing any mold spores left after remediation and better still prevent mold from reappearing.

Replacing moldy grout is yet another alternative. Simply scrap off moldy grout using the flathead screwdriver then apply a new layer o grout mixture. Just so that you achieve maximum protection from mold, apply a top coat of grout sealer.


Mold Remediation – How to remove and cleanup mold

Mold Remediation – Removal and Cleanup

The recommended and most effective way of addressing wide spread, toxic mold in your home is to employ the professional mold removal and remediation services. On the other hand, small (covering an area less than 10sq.ft.) non-toxic molds can easily be removed through the simple DIY remediation process.

Mold Remediation in Summary

Below is a summary of the basic process of remedying and minimizing mold.

  1. Put on protective gear
  2. Have the mold spores under control
  3. Employ negative pressure
  4. Take out the mold
  5. Prevent mold from returning
  6. Clean your items
  7. HEPA vacuum
  8. Get rid of the mold

Put on Protective Gear

Mold remediation will certainly unsettle mold spores, leaving them floating randomly in the air. This is why mold protective gear are vital when remediating mold.

You can at least have the following before beginning a mold remediation process.

  • Goggles
  • Protective easy-to-clean or easy-to-dispose clothes covering your entire body
  • Dust filter mask or respirator
  • Gloves

The above represent the basic protective gear one should have. However, the protective equipment to be used depends on how grave the mold problem is and how far it has spread.

Contain the Mold Spores from spreading

Containing widespread mold might mean sealing off the affected room to ensure that no mold spores will spread to the rest of the rooms. This will require clean nylon sheets fixed firmly with a duct tape on all openings such as doors.

It is important to note that as you contain mold spores, you also need to reduce dust. This is because dust particles always travel together with mold spores and this may result in mold spreading to other areas.

Use Negative Pressure

Naturally, air flows from areas with higher pressure to those with lower pressure. By creating negative pressure in the mold-affected room, you will run an exhaust fan and direct the flow of air out of a window.

This way you will create high pressure inside the room and this automatically causes air, mold spores included, to flow out through the window. Make sure your air conditioning is turned off as it may affect the remediation process.

Take Out the Mold

This process usually causes a stir up of mold spores back into the air, especially when the mold is dry. What you can do to prevent this is to dampen the mold by spraying water on it using a spray bottle.

Once this is done, use the recommended solution for your type of surface to take out the mold. Examples of some commonly used solutions are

  • Ammonia for hard impermeable surfaces
  • Bleach for hard impermeable surfaces like glass and tiles
  • Borax for all types of surfaces
  • Vinegar also good for spraying on most surfaces

Prevent Mold from Returning

If the mold remediation process is to be rated successful, this stage must not be overlooked. Cleaning all surfaces, both those that had and those that didn’t have mold, with a mold cleaning solution will prevent mold from growing again in future.

Clean Moldy Items and Protective Gear

Cleaning moldy items depends on the material they are made of. Impermeable items are often easier to clean and reuse after being affected by mold because mold does not penetrate them.
On the other hand, permeable items like books and carpet may not be as easy to clean off all mould on them. At this point, you might be forced to make a decision of whether to retain or dispose of them. For some, disposing may be a great idea because it will prevent re-growth of mold in future.

HEPA Vacuuming

HEPA Vacuuming is the process of clearing any remaining mold spores from the atmosphere. It is an out of the ordinary vacuuming process that clears very fine particles and so is suitable for removing mold spores.

It is recommended that this be done after removing mold, sanitizing all surfaces, and giving them time to dry out all form of liquid.

Dispose of the mold

This is the final step after clean-up, taking-out mold, sanitizing, and HEPA vacuuming has been done. Moldy items set for disposal as well as the contents of the HEPA vacuum must be carefully kept away in sealed plastic bags. To avoid recontamination with mold, these bags should not be dragged through the home while cleaning the rest of the rooms but be thrown out through the window and discarded.
Again, the entire mold remediation process is best done one room at a time, if the process is to be a success.

Mold removal guide – Removing mold with common household cleaners

Mold Removal Products

There are several common household cleaning items that can be used to remove mold from your house. Some of these cleaning agents are quite strong while others are moderate. Depending on the mold quantity and the underlying surface on which the mold has grown, you need to select the right cleaning solution.

Here is a list –

  • Vinegar
  • Hydrogen peroxide
  • Bleach
  • Ammonia
  • Detergent
  • Baking soda
  • Borax
  • Tea tree oil
  • Grapefruit seed extract

1. Mold Removal with Vinegar

Vinegar contains acetic acid which is a mild acid, but is capable of killing most mold species that are commonly found in bathrooms and kitchens. Vinegar has the advantage of being a natural cleaner that is non-toxic and safe for any kind of use.

Vinegar works quite well on tiles, vinyl and porcelain surfaces. If there is mold on the tiles or on the vinyl door in the bathroom then you can clean it with just vinegar.

Fill a spray bottle with plain white vinegar and spray vinegar on the mold affected area. Leave for a few minutes and then wipe using a sponge. The mold would easily come off along with the dirt and water stains. Its as simple as that.

Keep cleaning till all the mold is gone and the whole surface is looking bright and clean. Vinegar also acts as a disinfectant which kills other kinds of germs and microbes as well. It should be your first choice when cleaning mild and regular molds in kitchen and bathroom.

To make the cleaning even better, try adding lime or lemon juice to the vinegar.

If you are using it in the kitchen then make sure not to spill it on granite or marble floor or countertops. The acid in vinegar can corrode stone surfaces.

Vinegar can also be used to clean mildew from clothes. Clothes left wet for many days often develop a musty smell and mildew growth. Simply wash the clothes with warm to hot water with laundry detergent and a cup or two of plain white vinegar.

2. Mold Removal with Detergent and Water

Usual laundry detergent can also be used to clean up mold from a variety of surfaces. Prepare a solution detergent and water and use it to scrub the mold. This will work on wooden surfaces, ceramic tiles, porcelain and vinyl surfaces.

If you are cleaning mold on walls, then prepare a stronger detergent solution with more detergent and less water. Walls will also need more time and effort to completely clean away the mold.

3. Mold Removal with Baking Soda

Baking soda is a very common household cleaner that is natural and non-toxic. Though it is not a very strong cleaner, it can still be used to clean small amounts of mold in the house. Baking soda in solution is alkaline (pH 8.1) in nature so it can be used on surfaces that need an alkaline cleaner. Moreover its safe for humans and pets.

Add about 1 tablespoon of baking soda in 1 spray bottle and fill it with water. Add 1 teaspoon of liquid dishsoap. This will enhance the cleaning power of baking soda. Shake and mix the solution well.

Now spray this solution whatever mold surface and scrub and wipe with a sponge or scrubber. Repeat the process till all the mold is gone. Baking soda solutions are good for use on stone surfaces like marble and granite and also polished wooden surfaces.

For tiles and vinyl doors, vinegar and lime juice will always be more effective.

4. Mold Removal with Borax

The next mold cleaner we are talking about is Borax. Borax is a natural cleaning agent, but is toxic if consumed. However borax is still safer as it does not emit toxic fumes like bleach or ammonia. In water solution borax is alkaline with a pH level of 9 (higher than baking soda). So it has a similar cleaning effect like baking soda.

Borax is quite useful for cleaning toilets and drains. It has disinfectant properties and acts as a insecticide, herbicide and fungicide. This makes it a good cleaner for mold as well. It is cheap as well.

Using borax to clean mold

Prepare a solution of about 1 cup borax in 1 gallon of water. Add 2 tablespoon of liquid dishsoap to the solution.

It is advisable to vacuum the area before cleaning with borax solution. Use a HEPA filtered vacuum cleaner to pull out all loose mold and mold spores in the air. This will make cleaning easier and better.

Now apply this solution on the mold area in plenty and then rub with a scrubber. The mold should start falling off.

After cleaning, let the surface dry completely. Vacuum once more to make sure that no particles or mold spores are left behind. If it is indoors, then ventilate the place well with open windows and fans.

5. Mold Removal with Hydrogen Peroxide

Hydrogen peroxide is yet another effective cleaner that can be used to remove mold. It has anti-fungal, anti-viral and anti-bacterial properties which make it a good disinfectant. Hydrogen peroxide acts as a mild bleach but is a lot safer that chlorine bleach. It does not give out any toxic fumes and is much safer on humans and pets. It can be used to remove mold from floors, walls, tiles, fixtures etc.

You can purchase hydrogen peroxide from your local drugstore. Most of the commercially available hydrogen peroxide has 3% concentration, which is safe for household usage.

Fill a spray bottle with 3% hydrogen peroxide. You can also use 5% hydrogen peroxide.
Spray it on the moldy surface in plenty to make sure that all the mold is covered by the hydrogen peroxide. Leave it for around 10 minutes so that the peroxide can do its job of killing the mold. Then scrub away the entire surface with a sponge or scrubber.

Repeat the process till all the mold is wiped away. After cleaning you can vacuum the surface to ensure that all the mold spores have been eliminated away and there is none left.

6. Mold Removal with Bleach

Bleach is perhaps the strongest chemical that you can use to kill and remove mold. It completely eliminates mold from whatever surface it is applied to.

However, bleach is a toxic and strong chemical that needs to be handled with great caution. Bleach should be used only as the last resort when all other cleaners fail to do the job. If you are cleaning mold from some outdoor wooden structure that is large in size and does not clean well with vinegar or detergent, you may have to use bleach.

Bleach comes in two different variants, namely chlorine bleach and oxygen bleach. For indoor usage like bathrooms, oxygen bleach is a safer options. Oxygen bleach is less powerful than chlorine bleach but is effective in cleaning mold.

Precautions when using bleach

When using bleach, make sure that you use hand gloves and face masks to protect yourself from the fumes. Also keep in mind that never mix anything with bleach without proper knowledge. A number of chemicals like vinegar or ammonia react with bleach and produce highly poisonous gases which can be fatal if inhaled even in small quantities.

How to Kill Mold with Bleach

First prepare a solution of 1 part water with 10 parts water, or about a cup of bleach in 1 gallon of water. Preferably use a medium sized tub or bucket that can be carried safely without spilling.

Now use a large sized sponge to soak the solution and then apply it on the moldy surface. Rub as much as you like till the mold is completely gone. Repeat the process as necessary.

For outdoor structures, do not rinse with fresh water. Let the bleach remain on the surface so that it has effect for as long as possible.

7. Mold Removal with Ammonia

Like bleach, ammonia is also a very strong chemical agent that can up mold. It can be used on glass, tiles, countertops etc. Ammonia is strongly alkaline in nature.

Ammonia is a harsh, toxic chemical that should be handled with great caution. Also make sure to never mix anything else with ammonia like bleach or vinegar. This will result in highly toxic gases to be released that can be fatal if inhaled.

Additionally, although ammonia can kill surface mold, dead mold and dead mold spores are still allergenic so you will need to make sure to remove them afterwards.

How to Kill Mold with Ammonia

To kill mold using ammonia, create a solution of 50% clear ammonia and 50% water in a spray bottle and spray it on moldy areas.

Make sure the ammonia you use says “clear ammonia” on the label.

Leave the area for a few hours before wiping and rinsing.

Often detergents or mold cleaning products will contain ammonia. In that case just follow the directions on the label and be sure never to mix it with bleach.

Mold Control with Tea Tree Oil

So far we have discussed some of the most effective way of cleaning the mold away. Now its time to apply something that will hold the mold back from growing again.

Tea tree oil is a natural and effective solution to hold the mold from coming back for some time. It may not be the best solution to clean large amounts of mold, but after you are done cleaning using bleach or vinegar, try applying tea tree oil to prevent mold growth for some time.

Tea tree oil is an essential oil that is mostly safe on the skins of humans and pets. However it is toxic if consumed. When used sparingly in diluted form it has strong antimicrobial and antifungal properties.

The best quality tea tree oils are derived from a plant called Melaleuca Alternifolia which is very commonly founds in Australia.

Applying Tea Tree Oil

First of all you should clean away as much mold as you can using vinegar or lime juice. Use a little baking soda if necessary.

Now prepare a solution of 1 teaspoon tea tree oil with 1 cup of water. Fill it in your spray bottle.

Spray the solution on the moldy surface very generously. Saturate the whole area with oil solution. Do not rinse or wipe the area, let the solution sit over the mold surface so that it can keep doing its work and hold the mold from returning.

However, bear in mind that natural remedies like these will work only on small places that are otherwise well ventilated. For outdoor structures that are more exposed to water and moisture you better call in professional service.

Mold Control Grapefruit Seed Extract

Grapefruit seed extract is another oil extract similar to tea tree oil that has anti-fungal properties. It is inexpensive and safe on humans and pets. Unlike tea tree oil, it does not have any

The citric acid in the grapefruit seed extract acts as a strong disinfectant that kills microscopic molds and spores. It also deodorizes the whole surface.

Again, just like tea tree oil, grapefruit seed extract is also not a cleaner. First you should clean the mold with cleaning solutions of vinegar or bleach and then apply grapefruit seed oil.

Also this technique is useful only for indoor areas that are small in size. For a large scale mold treatment you would need to use commercial mold inhibitor solutions or call professionals.

Applying Grapefruit Seed Extract

Prepare a solution of 10 dropts grapefruit seed extract in 1 cup of water. Fill your spray bottle with it.

Shake the bottle well and then spray the solution onto the mold area. Spray in plenty to fully cover the whole mold ridden area.

No need to wipe or rinse. Let the solution stay on the surface like that. It will do its work and hold the mold from coming back for several weeks. Depending on how soon the mold reappears, you can spray the solution again after a few weeks to keep it in effect continuously.


Tackling mold can be a grueling task. If you are doing it for the first time then you need to first cleanup the mold completely using all possible measures.

Next you have to take necessary steps to control the mold from reappearing soon. Although this is not easy and there is probably no solution that will hold the mold forever. Most mold control solutions stay in effect from few days to few weeks, after which you have to treat the surface again.

Using the above mentioned methods you can get rid of mold pretty easily using common household cleaning supplies that are not very expensive.
