How To Remove Mold Stains
Mold is a common term given to fungi in almost all parts of the world. Mold consists of a white substance called mycelium. Mold looks like velvet. It grows in area where moisture is present. Once mold has conditions for growth, it grows rapidly and spreads. When the conditions for growth do not exist, the mold becomes powdery and can be easily airborne and spread through air. Where it finds conditions encouraging growth, it starts growing again without difficulty.
