The 30 Seconds Outdoor Cleaner is a liquid spray designed to quickly remove moss, algae, mold, and mildew stains from various outdoor surfaces like decks, vinyl siding, and patios. Its cleaning power is solid for organic stains, making it effective for outdoor grime buildup. The product is safe for lawns, trees, and shrubs when used as directed, which indicates it is gentle enough for surrounding vegetation and suitable for those concerned about chemical runoff near plants.

The application is straightforward: you attach a hose-end sprayer to the bottle, spray the surface, then rinse with water, eliminating the need for additional tools like pressure washers. This easy method is convenient, especially for homeowners without specialized equipment. Coverage is about 900 square feet per bottle, so having three bottles is helpful for larger cleaning jobs.

This cleaner is a good choice for those looking to remove organic stains from a variety of outdoor surfaces with an easy spray-and-rinse application. If your primary goal is shingle roof cleaning, it is advisable to ensure it’s suitable for your roofing type or explore products made specifically for shingles.

Wet & Forget Outdoor Stain Remover is designed to clean roofs and other outdoor surfaces gently over time, making it a good fit for those looking to remove moss, mold, mildew, and algae without harsh scrubbing. Its hose-end spray nozzle offers easy application from a distance, reaching up to 30 feet, which can make treating large areas less physically demanding. The product is bleach-free and non-acidic, which helps protect shingles from damage, making it relatively safe for shingle roofs compared to stronger chemical cleaners.

This product works slowly, relying on rain and wind to clear stains over weeks or even months, so it may not be suitable if immediate results are needed. It does not require rinsing, reducing the risk of residue buildup that can sometimes harm surfaces or plants. It is somewhat environmentally friendly, given the instructions to avoid spraying near water bodies and to flush plants after use, though it is not explicitly labeled as fully biodegradable.

Each bottle covers a large area, but heavily stained or porous surfaces will require more product, possibly necessitating multiple treatments. This cleaner is ideal for homeowners who prefer a low-effort, gradual cleaning solution and prioritize safety for their roofing materials over rapid stain removal.

Wet & Forget Moss, Mold, Mildew, & Algae Stain Remover is designed to clean roofs and other outdoor surfaces without scrubbing or pressure washing, making it gentle and safe for shingle roofs. Its cleaning power is gradual—green stains typically fade within a couple of weeks, but tougher black stains or heavy buildup may take several months, so patience is needed.

The product is applied by mixing it with water in a sprayer and simply coating the dry surface; it works with wind and rain to clean naturally over time. This no-rinse method helps prevent damage to shingles that aggressive cleaning can cause. Wet & Forget is fragrance-free and biodegradable, which means it is environmentally friendly and won’t leave harmful residues on your roof or surrounding areas. Users should apply it during cooler conditions and avoid rain for a few hours after spraying to ensure effectiveness.

While it doesn’t provide immediate results like some cleaners, this product offers a low-maintenance choice for those wanting to keep shingles clean and protected without harsh chemicals or heavy labor. It is best suited for homeowners looking for an easy, long-term solution rather than a quick fix.
