Wet & Forget Outdoor Moss, Mold, Mildew, & Algae Stain Remover is a liquid moss killer designed for easy application via a hose-end sprayer, which can reach up to 30 feet. This makes it well suited for treating roofs, siding, driveways, patios, and decks without the need for scrubbing or rinsing. Its active ingredients are bleach-free and non-acidic, which reduces risk to plants and pets if used carefully, though it still advises keeping the spray away from water bodies and rinsing plants before and after use. One bottle covers up to 2,000 square feet, but heavy or porous surfaces may absorb more product.

The cleaning process is gradual: green stains typically fade within 1-2 weeks, but tougher black or old stains may take several months, even up to a year in some cases. The product’s effect can last a year or longer, offering lasting protection against regrowth. However, it requires specific weather conditions for application—spray only on dry surfaces, with temperatures above 55°F, and avoid rain for 4-5 hours after to ensure effectiveness. This slow-acting approach may not be ideal if you need quick results.

Wet & Forget provides a convenient and gentle option for homeowners who prefer a no-scrub, low-effort solution for moss and similar stains across various outdoor surfaces. Its long-lasting effect and plant-safe formula are strengths, but patience is needed to see full results, and careful application is important to protect surrounding plants and water sources.
