Will Vinegar And Hydrogen Peroxide Kill Mold?

Wearing protective gloves, goggles, and a mask while cleaning mould in your house will help you avoid coming into touch with mould spores.

Here’s how to use hydrogen peroxide to remove mould from solid surfaces:

  • Fill a spray bottle with 3-percent hydrogen peroxide (the typical concentration seen in pharmacies). Spray it on the mouldy area until it fully covers the area.
  • After 10 minutes, or when the hydrogen peroxide stops bubbling, let it sit.
  • Use a soft brush or towel to scrub the mould and hydrogen peroxide away. To prevent hurting the surface below the mould, begin by softly scrubbing, and then gradually scrub harder as necessary.
  • When finished, use a fresh cloth or rag to wipe the area dry.
  • If necessary, repeat.

One of the numerous commonplace chemicals you can use to remove mould is hydrogen peroxide. Another efficient method for removing mould from your home is vinegar.

Peracetic acid is a poisonous chemical that can hurt your eyes, skin, or lungs when hydrogen peroxide and vinegar mix.

Bleach is frequently used to remove mould from dwellings. Despite the fact that bleach can be useful for removing mould from hard surfaces, extended exposure to its fumes can cause irritation in the eyes, lungs, and skin. The likelihood of people with asthma or respiratory conditions being disturbed by these pollutants is very high.

Can mould be removed with hydrogen peroxide?

Cleaning removing mould can be done using a variety of products. Among the things that kill mould well are:

  • Bleach
  • Borax
  • Vinegar
  • Ammonia
  • hydroxyl radicals
  • Detergent
  • bread soda
  • Oil of tea tree
  • juice from grapefruit seeds

Although these solutions have the potential to destroy mould, their effectiveness depends on your ability to spot the earliest signs of mould formation and stop it from spreading. You must get rid of the moisture source that caused the mould to appear in the first place in addition to the visible mould. While doing it yourself to get rid of the mould may be an option for many people, it is frequently done insufficiently and only offers a short-term fix.

If you see mould in your house, it is usually preferable to contact a professional mould remediation business. However, if the mould is not poisonous and the area of growth is limited (less than 10 square feet, or around a 3 by 3 foot patch), you can try to handle the mould remediation on your own.

Mold Removal Using Bleach

Every species of indoor mould that bleach comes into touch with, including mould spores, is killed, leaving a surface that is sterilised and resistant to further mould growth. Bleach, however, is only efficient if the mould is developing on non-porous surfaces like tiles, bathroom fixtures, glass, and counters.

Bleach cannot remove mould developing below the surface of porous materials like wood and drywall because it cannot penetrate these materials. Only the mould on the surface will be eliminated if you use bleach to remove mould from these surfaces. The mould will quickly reappear because it won’t be able to reach the mould inside the material.

Being a strong, caustic chemical, bleach has the potential to harm the materials it is applied to. When combined with ammonia, it releases poisonous gases as well as unpleasant smells. Borax or vinegar are safer substitutes that don’t emit the hazardous vapours or leave behind poisonous residue.

  • Use 1 cup of bleach for every gallon of water (ie about 1 part bleach to 10 parts water)
  • Apply the remedy using a spray bottle or a bucket and sponge to non-porous surfaces that have mould development.

How to Use Borax to Kill Mold

A natural cleaning solution with many benefits is borax. While it is poisonous if swallowed, unlike other mould removers, it does not release chemicals or hazardous gases. Borax needs to be mixed with water in order to eradicate mould. A natural mould inhibitor is borax.

  • Use 1 cup of borax to 1 gallon of water to make a borax-water solution.
  • To reduce the amount of mould spores churned up into the air during the cleaning process, suction loose mould with a HEPA filtered vacuum cleaner.
  • Scrub the mould off the surface using a scrub brush and the borax-water solution.
  • Eliminate excess moisture and mould excretions by wiping them up to stop them from dispersing into the air.
  • After using the borax solution, do not rinse it off.
  • Observe the surface drying.

How to Remove Mold with Vinegar

Vinegar is a moderate, natural acid that may eradicate 82% of all mould species. Additionally, it doesn’t release harmful gases like bleach does. Spray vinegar on the surface and let it sit for a while if you want to use vinegar to stop mould growth on surfaces. Repeat several days in a row to keep the surface clear of mould.

  • Without dilution, pour vinegar into a spray bottle.
  • Vinegar should be sprayed onto the mouldy area.
  • Give it an hour to sit.
  • Clean up the spot, then let the surface air dry.

Removing Mold with Ammonia

Ammonia will, like bleach, kill mould on hard, non-porous surfaces like countertops, glass, or tiles, but it won’t work as well on porous surfaces like wood or drywall. Ammonia is also a poisonous, caustic chemical. Although dead mould and dead mould spores are still allergenic, ammonia can destroy surface mould, therefore it is still important to remove these as well.

  • In a spray bottle, mix 50 percent clear ammonia and 50 percent water.
  • On the mouldy spots, mist the solution.
  • Check the label of the ammonia you use to be sure it reads “clear ammonia.”
  • Before wiping or rinsing, let the area sit for a couple of hours.

Using Hydrogen Peroxide to Kill Mold

Because it is harmless, doesn’t harm the environment, doesn’t leave behind poisonous residue, and doesn’t emit toxic fumes as bleach does, hydrogen peroxide is a wonderful substitute for bleach when trying to get rid of mould. Mold may be effectively removed from surfaces like clothing, floors, bathroom fixtures, walls, and appliances by using hydrogen peroxide.

  • Fill a spray bottle with hydrogen peroxide with a 3% concentration.
  • Completely saturate the mouldy surface with hydrogen peroxide by spraying it there.
  • Give the surface 10 minutes to sit.
  • Make careful to scrub the area thoroughly to get rid of all the mould and mould stains.
  • To get rid of any remaining mould and spores, wipe down the surface.

Killing Mold with Detergent and Water

Surface mould can be removed from non-porous surfaces using detergent and warm water. Mold can be removed with a solution of detergent and water as long as it is on non-porous surfaces.

How to Get Rid of Mold with Baking Soda

Baking soda is a mild, safe, and natural household cleaning that won’t hurt your family or pets. It also eliminates mould. Since both vinegar and baking soda are effective against various types of mould, they are frequently used when dealing with a mould issue.

  • A spray bottle of water should contain one-quarter of a spoonful of baking soda.
  • To get the baking soda to mix with the water, shake the bottle.
  • the mouldy area with spray.
  • All of the mould on the surface should be removed with a sponge or scrub brush.
  • Rinse the area with water to get rid of any remaining mould once the mould has been scraped away.
  • Re-spray the area and allow it to air dry.

Using Tea Tree Oil to Kill Mold

The most effective all-natural method for eliminating mould is tea tree oil. Tea tree oil is a more expensive choice, but a little goes a long way in getting rid of mould. It is an antifungal that can eliminate any kind of mould. Make certain that the tea tree oil you buy to get rid of mould is made from Melaleuca Alternifolia.

  • One teaspoon of water for every cup of water should be added to a spray bottle along with tea tree oil.
  • Onto the mouldy area, mist the solution.
  • Never rinse the solution off.

Getting Rid of Mold with Grapefruit Seed Extract

Natural mould remover made from grapefruit seed extract works well. Most health food stores sell it, and there is hardly any odour about it. The mould is attacked by the grapefruit’s citric acid. Additionally, it deodorises and sanitises the space.

  • Grapefruit seed extract and water should be combined in a spray bottle at a ratio of 10 drops of the extract per cup of water.
  • Spray the solution over the area where mould is forming after thoroughly mixing it in the spray container.
  • After that, rinse the solution off. More mould will be cut through and prevented from growing the longer the grapefruit seed extract is in touch with the mould.
  • Repeat as necessary.

How quickly can hydrogen peroxide remove mould?

Most home medicine cabinets contain hydrogen peroxide since it is an antifungal, antiviral, and antibacterial solution used to prevent infection in wounds. However, it’s also an effective mould remover, particularly when used with solutions that contain more hydrogen peroxide than 3%.

On porous and non-porous surfaces, such as clothing, bathroom accessories, and even kitchen equipment, hydrogen peroxide works best. However, because it’s a bleaching agent, make sure to spot test the area to make sure the fabric won’t fade before cleaning.

Fill a spray bottle with a 3 percent hydrogen peroxide solution and leave it undiluted to destroy mould. Using the spray bottle, completely cover the mouldy area with the solution. Let it sit for 10 minutes. The hydrogen peroxide will kill the mould throughout this process. Make sure the area is completely mold-free by using an abrasive sponge, then let the hydrogen peroxide work its magic on the mould stain. To finish, dry the area with a fresh towel.

Baking soda mixed in water will remove mold.

Sodium bicarbonate, usually referred to as baking soda, is a more natural method of eliminating mould. It is a natural cleaner that can be found in most homes and is safe for both children and dogs. Due to its deodorising properties, baking soda can help eliminate both the mold’s smell and the mould itself. Since both vinegar and baking soda can destroy many types of mould, they are frequently used together to remove mould.

Put 1 teaspoon of baking soda and 2 cups of water in a spray bottle and shake vigorously to combine to destroy mould. Apply the solution to the mould and scrape it away with a sponge or scrub brush. Following a final coating of the baking soda solution and a rinse with water, the surface should be allowed to dry.

What effectively eradicates mould?

Mold does not just develop on the surface of porous walls constructed of cement, concrete, or stone. Additionally, it often spreads internally.

Therefore, the best remedy for mould on a porous (unsealed) wall is a mixture of hydrogen peroxide and distilled white vinegar.


One cup of borax and one gallon of hot water should be combined in a container. Shake vigorously with the lid on to completely dissolve the borax. Apply the solution to the troublesome area using a spray bottle.

Use a brush to scrub the mould from the wall, then clean it up, let it air dry, and repeat. Rinsing the solution off is not required. If you have addressed the mould problem’s root cause, the borax will aid in preventing the mould from coming back.

Vinegar and Baking Soda

Using vinegar to destroy and prevent mould growth on porous or nonporous walls is a very safe and effective method. According to studies, white vinegar kills 82% of mould spores. According to reports, it seeps into porous materials and destroys the mould at its source (4).

Without dilution, pour some white distilled vinegar into a spray container. Vinegar should be sprayed onto the wall, then left for an hour. Next, use a sponge and warm water to thoroughly clean the area.

It could be required to scrub the mould after vinegar has been used to clean the wall. We advise you to prepare a baking soda solution for this.

Mold can be eliminated naturally with the use of baking soda. Additionally, it deodorises and aids in eliminating the musty, wet smell brought on by mould. And finally, it takes up moisture, which effectively prevents mould growth.

One teaspoon of baking soda and two cups of water should be combined in a spray bottle and well-shaken to create a baking soda solution. To get rid of the mould, spray the afflicted area with the solution and scrub the surface with a scrub brush or scouring pad.

After that, give the area a warm water rinse to get rid of any remaining mould on the surface. To guarantee that all of the mould is eliminated, spray the wall once more with either the vinegar or baking soda solution.

Tea Tree Oil

Due to its antifungal and antibacterial qualities, tea tree essential oil is a highly efficient remedy for eliminating mold. To begin, fill a spray bottle with two cups of water and one teaspoon of tea tree oil. Spray the remedy on the mouldy spot, then remove it with a clean towel.

Rinsing is unnecessary because the tea tree oil will kill the mould and keep it from growing again if you leave it on the surface. For eliminating mould and mildew from painted and wallpapered walls, this technique is advised.

Grapefruit Seed Extract

Another highly efficient natural mould remover is grapefruit seed extract. Mold is naturally eliminated by the grapefruit’s citric acid, which fights it. Additionally, it serves as a deodorizer and disinfectant.

Use 10 drops of grapefruit seed extract to 1 cup of water to make a solution that may be sprayed. Spray the solution into the afflicted region after properly combining it in the bottle with a shake. After a few minutes, remove the mould and solution with a clean cloth.

Longer exposure to the grapefruit seed extract will effectively destroy the mould and prevent further growth. To stop it from growing back, you might wish to repeat this procedure every two to three days.


Mold can be killed by bleach on non-porous walls. On porous surfaces, it won’t get through and harm the roots. However, make careful to test some of the bleach solutions on a discrete area of the wall before you start cleaning. This assures that it will not damage the finish.

Apply the solution to the wall after combining one part bleach with three parts water. After waiting 10 minutes, use a brush to scrub the mold. Clean the area by rinsing with water and drying it with a fresh cloth.

Open the windows and doors and put on a safety mask before applying bleach. Inhaling the harmful gases that bleach emits might be just as risky as breathing in the mould itself.

Hydrogen Peroxide and Vinegar

Mold-killing hydrogen peroxide has outstanding antiviral, antifungal, and antibacterial properties. In addition to becoming stronger, hydrogen peroxide and distilled white vinegar also generate a mold-killing solution that is safe to use and, unlike bleach, doesn’t emit hazardous fumes or leave toxic residue behind.

Additionally, its effervescent qualities make it superior to bleach in terms of killing mould on porous surfaces. Both porous and non-porous walls can be cleaned using hydrogen peroxide.

Undiluted hydrogen peroxide at a 3 percent concentration should be poured into a spray bottle and applied to the affected area. After leaving on the surface for 10 to 15 minutes, use a brush to scrape the walls to get rid of the mold.
