Mold growth around the home should be eliminated as soon as it is discovered. Living spores in mold are harmful to the respiratory system and lengthy contact without adequate breathing protection should be avoided at all costs. A carpet with slight molding can be cleaned, but must be removed and discarded if heavily infested. Mold grows in warm, damp conditions and thrives in areas like bathrooms and basements. Ventilate rooms susceptible to mold as much as possible and check the areas for water leaks. You can mix a natural cleaning solution to kill mold spores in the carpet with ingredients in your home and they're the best carpet cleaning agents for mold growth, as they will not damage the carpet fibers or cause discoloration.
Brush as much excess mold as possible off the carpet with a soft bristled brush.
Vacuum the mold area thoroughly.
Mix 1/2 cup of borax powder, 1/2 cup white vinegar with 1 cup of water in a cleaning bucket and pour into an empty spray bottle. Borax powder is a natural cleaner that will kill the mold spores on the carpet. Vinegar is also a natural cleaning product. You can purchase both items in general or hardware stores.
Spray the mold-infected areas in equal amounts on the carpet with the vinegar and borax solution and allow to sit for 15 minutes.
Blot up excess moisture with an absorbent cloth and allow the carpet to fully air dry.
