It’s applied generously on a dry surface and allowed to weather away with wind and rain. Ideal for porch steps, planters, and canvas or upholstery surfaces that tolerate outdoor exposure.

Best for larger exterior areas like driveways, decks, and roofs where a concentrate is practical. Mix 1 part Wet & Forget with 5 parts water in a garden sprayer, spray dry surfaces, and let wind and rain do the work.

Buying Guide: Key Purchase Considerations
- Surface compatibility: Choose products labeled for decks, driveways, roofs, or siding based on your target areas.

- Stain type and severity: Green, algae, and moss stains often fade quickly; black or older stains may require longer exposure.
- Safety and surface care: Test on a small area if you’re unsure about delicate or newly painted surfaces; follow directions for temperature ranges.
- Coverage area: Check sq ft coverage per bottle or per bottle-dilution to estimate total purchases for larger projects.
