What Household Products Claim to Kill Mold on Surfaces?

Bleach is a common household product that many people use against mold on hard, non-porous surfaces like tile, glass, and countertops. It can kill surface mold in these areas, but it does not penetrate porous materials such as drywall, wood, or carpet. As a result, mold roots can remain and regrow.

Using bleach on porous surfaces can actually feed the mold, because the water in the bleach solution soaks into the material. For mold on drywall or wood, the affected section usually needs to be removed and replaced. If you are unsure about the surface type, test a small area first or consult a professional.

• Effective on non-porous surfaces only
• Can damage certain materials like metal
• Fumes can be strong, so ventilate the area
• Never mix bleach with ammonia or other cleaners
• Wear gloves and eye protection when using

White vinegar is a mild acid that some people use to kill mold on hard surfaces. It is less toxic than bleach and can be sprayed directly on mold. Vinegar may work on small patches, but it is not a strong disinfectant and may not kill all mold types.

Baking soda is often used with vinegar or water to scrub mold off surfaces. It can absorb moisture and help with odors. While these products are safe for many surfaces, they are not a complete solution for mold that has penetrated into materials or spread over a large area.

Before cleaning mold, protect yourself with gloves, goggles, and an N95 mask. Open windows and doors for ventilation. Never mix cleaning products, as this can create toxic fumes. If you feel unwell during cleaning, stop and see a doctor.

Also, remember that mold is a health concern, especially for people with allergies or asthma. If you are unsure about handling mold yourself, or if the affected area is large, it is safer to call in a professional. They have the training and equipment to handle the job properly.
