Wet & Forget Outdoor Moss, Mold, Mildew, & Algae Stain Remover 64 Ounce

The Wet & Forget Outdoor Moss, Mold, Mildew, and Algae Stain Remover is a multi-surface cleaner that comes in a 64-ounce ready-to-use bottle with a high-capacity trigger sprayer for convenient application. This solution effectively removes green and black stains caused by moss, mold, mildew, and algae without the need for scrubbing, rinsing, or pressure washing. Simply apply it to a dry surface on a cool day, ensuring no rain is forecasted for at least 4-5 hours and the temperature is above 32°F. The product cleans over time with the help of wind and rain, with results appearing within weeks for green stains and several months for more stubborn black stains. It is bleach-free and non-acidic, making it suitable for various surfaces like porch steps, headstones, fountains, planters, concrete, canvas, and upholstery. Each bottle can treat 60 to 180 square feet, depending on the surface porosity and stain severity.
