Black mold on a white wall

If you’re looking to get rid of mold in your home, getting the right DIY mold remediation product is necessary.

When it comes to mold remediation, it’s not all about eliminating the mold; correct cleanup involves containing the spore, stopping the mold’s return, and disposing of the mold efficiently.

Note: proper remediation demands the right products.

The United States Environmental Protection Agency (EPA) recommends that you have to be extremely careful when picking a mold remediation product.

Here are a few effective DIY products to consider.

  1. Bleach

Bleach is a go-to product when dealing with indoor mold. Bleach is even effective in getting rid of spores, ensuring surface sanitation, and preventing future mold growth.

Note that bleach is only recommended for non-porous materials like countertops, glass, bathtubs, and tiles.

Bleach is incapable of penetrating porous materials like drywall or wood. It merely attacks the surface, and the mold would likely resurface after a while.

Chlorine bleach emits harsh fumes so before using it to kill mold, wear a protective mask and gloves, and ensure the space is well ventilated.

To form your cleaning solution, mix one cup of bleach with one gallon of water.

Use a soaked cloth or sponge or a spray bottle to apply the bleach to a non-porous surface.

Rinsing the surface afterward is not necessary unless kids may touch it, or the area is for food. Sadly, as effective as bleach is, it is quite corrosive and emits toxic gas when combined with ammonia. 

  1. Borax

Unlike chlorine, borax—a white mineral powder—is a mold-remediating product that does not emit toxic fumes. While poisonous when eaten, borax is effective in getting rid of mold.

While borax is traditionally used to clean drains and toilets as well as a deodorizer, it can eliminate mold growth when mixed with water.

A mold-killing, borax-water solution is created with a cup of borax in one gallon of water. And unlike bleach, you do not have to rinse off the surface after applying the borax solution.

3. Vinegar

Vinegar has mildly acidic qualities, so it’s a proper mold remediation product.

While natural and safe, vinegar does not emit harsh fumes. 

A non-diluted white distilled vinegar can be used.

Pour it into a spray bottle, and don’t add water.

After spraying on the contaminated area, let it sit for an hour, clean the surface with water.

For good results, keep applying some vinegar every few days. 

4. Ammonia

Ammonia is useful for removing mold on non-porous surfaces like tiles or glass.

Many mold-cleaning products on the market contain ammonia. However, it is a toxic chemical, and must not be mixed with bleach. The reaction gives a dangerous gas.

While ammonia can eliminate surface mold, you should clean the surface afterward to reduce the risk of allergies.

To create an ammonia cleaning solution, mix clear ammonia and water (50:50) in a spray bottle. Ensure that the ammonia container says “clear ammonia.” After applying, let it sit for two hours or more. 

5. Hydrogen Peroxide

Hydrogen peroxide’s antifungal property makes it great for mold removal. While Hydrogen peroxide is a bleaching agent, it does not emit toxic fumes like chlorine, and you can purchase it in the store at 3% concentration.

Hydrogen peroxide is effective for porous and non-porous surfaces and attacks mold spores effectively.

Use a spray bottle to apply undiluted 3% concentration hydrogen peroxide to the affected surface and leave for 10 to 15 minutes. After the chemical saturates, scrub the area and wipe down mold residue.

A solution of hydrogen peroxide and vinegar is quite useful too. Just store the spray bottle somewhere dark as sunlight tends to weaken the effectiveness of hydrogen peroxide.

6. Detergent and Water

A solution of warm water and detergent works for non-porous surfaces when trying to get rid of mold. While this solution won’t kill the mold, it can wash it off thoroughly.

7. Baking Soda

Baking soda’s absorbing and deodorizing properties make it great for eliminating mold. It is harmless and takes out that moldy smell. A solution of vinegar and baking soda is more effective.

Mix ¼ tablespoon of baking soda with water in a spray bottle, shake until the baking soda dissolves, and you’re ready to go.

After spraying the baking soda solution on the affected area, a scrubbing brush or a sponge can then be used to remove mold from the space.

After scrubbing, rinse the area with water to get off residual mold, then re-spray the surface with more baking soda solution, and let it dry. 

  1. Tea Tree Oil

Tea tree oil is an organic solution to remediating mold. While this is an expensive DIY product, tea tree oil is quite effective in killing mold.

Harmless to humans but capable of killing mold, tea tree oil’s antifungal property is something you can bank on.

Mix a teaspoon of tea tree oil with water in a spray bottle. After spraying the solution on the surface, don’t rinse it with water. Just use a cloth or rag to wipe off the mold.

Note that tea tree oil has a strong odor, but it will dissipate over time. Fortunately, tea tree oil has a long shelf life so that you won’t lose effectiveness so soon.

Final Note

Before choosing a DIY product, be mindful of the kind of the contaminated area. Wood, cement, or brick may demand a different type of mold remediation product.

  1. I like the bleach and baking soda method the best. These are both items we have at home. Ever since I was a child, I’ve always used bleach to clean. My family thinks it’s weird I use so much bleach, but now everyone is happy about it.

    We have some mold build up in our washroom, I have never thought about using bleach on that. Can I combine both bleach and baking soda to get an effective clean?

    • Yes, bleach and baking soda can be combined safely and together they are an improved cleaning formula. Thanks for your question and your comments. All the best, Bob

  2. Great post. I’ve just moved into an old house and have noticed a bit of mould here and there. I love that you’ve included things like vinegar and baking soda. I never would have thought to try these but they may just be the perfect solution as I have a baby and didn’t want to use anything toxic.
    Can vinegar be used on a porous surface like wood do you think?

    • Hi, Vinegar is an acidic solution that can cause porous surfaces like wood, stone, and grout damage. It can be mitigated if it is heavily diluted with water. Thanks for the compliment and your question. All the best, Bob

  3. Molds overgrow during the rainy seasons after the winters here in Japan. And that’s my major problem during these seasons. I’ve tried so many solutions that are in the market but couldn’t find one to help me with my cleaning.

    I’m so glad to come across this article, this could be the solution to my problem, I’ll try to test the bleach one or I prefer your recommendation if there is something better.

    Thank you,
    Lyn

    • Hi Lyn, Bleach is very good at getting rid of both mold and mold spores. Note that bleach is only recommended for non-porous materials like countertops, glass, bathtubs, and tiles. Hydrogen peroxide is effective for porous and non-porous surfaces and attacks mold spores effectively. All the best, Bob
