How to kill white mold

Updated March 23, 2017

Mold and mildew can take many forms -- including a fuzzy white fungus that appears on a number of surfaces in the home, such as fabric, paper, wood and tile grout. White mildews and moulds flourish in warm summer months, although they can present themselves at any time. It's best to prevent white mildew and moulds by ensuring proper air circulation in your home, and using a dehumidifier in vulnerable areas, such as basements and bathrooms. However, once you spot white mildew and mould, you can kill and remove it using safe household cleansers.

Place on protective gloves.

Mix a ratio of 2 tbsp of liquid bleach to 1 quart of warm water in the bucket.

Dip one sponge into the bleach-water mixture.

Scrub the white mildew/mould well with the wet sponge.

Allow bleach-water to sit on the white mildew/mould for at least five to 10 minutes.

Wet the second sponge with clean, warm water and rinse area.

Dry well with the rag.

Repeat Steps 1 to 7 for each instance of white mildew/mould.
