For eliminating mold stains without replacing entire sections of walls or flooring, mold stain removers can be a great tool. Many mold stain removers get the job done on the first try and can provide protection for years, even in humid environments. Different products are designed for different surfaces, though some may be able to handle anything from concrete to drywall. Most mold stain removers are fairly safe and require little protection, but read the instructions carefully to make sure you are properly and safely using the product. Some mold stain removers come in a spray bottle, while others are a gel or a liquid that can be diluted with water.
