Wet & Forget concentrate is the ultimate outdoor moss, mould, lichen and algae remover that is safe to use on any exterior surface. It kills problem spores and helps stop premature regrowth of unwanted biological growth.
Wet & Forget can be used to treat many surfaces including:
Wet & Forget® has a unique combination of biodegradable selective surfactants for moss and mould removal on absolutely any exterior surface. When diluted with water and applied, it immediately attacks that unsightly moss and mould. Then Mother Nature takes over. The weathering process gently removes the decomposing growth away over time without damaging the surface it has infested.
Wet & Forget® is the safest, most effective way of removing moss and mould from ANY exterior surface.
How to apply Wet & Forget
Sweep all leaves, dirt and other debris off the surface before application to allow for maximum penetration of the active ingredients.
Dilute one part Wet & Forget to five parts water (1:5) in a garden or backpack sprayer.
Spray the affected area to the point of saturation. Do not hose off.
Apply during overcast, dry conditions to avoid accelerated evaporation.
Do not apply if rain is expected in the next 12 hours.
Lichen requires a second application within 15 minutes of the first.
Keep children and pets off the treated surface until dry (normally 1-2 hours).
If badly contaminated, apply a second application one month after the first.
When to expect results with Wet & Forget
Algae will disappear within days.
Moss will turn brown within a few days and other light growth will decompose within a few weeks.
Black mould will noticeably improve within 4-6 months, however if the area is heavily contaminated it will take 6-12 months.
Lichen requires two applications within 15 minutes of each other and will take 8-12 months to decompose.
Note: It is normal for some treated surfaces to turn an orange/brown colour after application. This discoloration indicates a good result, however it is not permanent and will soon disappear.
