How to Get Rid of Black Mold The first step is to isolate and remove moisture sources contributing to its growth or spread. Inspect damaged areas for water intrusion and repair any leaks beforehand. This could help prevent future infestations as well. It's also essential to ventilate high-humidity environments such as bathrooms, laundry rooms, basements, etc. Open windows often on sunny days and run dehumidifiers during damp weather when necessary. Fungicides can act quickly but must be applied directly to the affected area only. To ensure this, ensure they don't come into contact with any other items present at home, like furniture. If the fungicide comes into contact with these items, there will need to be extra effort and money put towards cleaning those items off again. If a fungicide isn't readily available, opt for a soap and bleach solution, which also works wonders. Just mix one part bleach with 10 parts warm or hot water before adding detergent until frothy bubbles start forming on top. Scrub all moldy spots using a sponge or rag dipped into this sudsy mixture. Afterward, let dry completely without wiping off the excess liquid residue left behind from the washing process first!
