What is Wet & Forget?

Wet & Forget Outdoor takes the hard work out of cleaning. It safely removes algae, moss, lichen, mould and mildew from outdoor surfaces. Are you tired of the never-ending job of keeping mould and mildew at bay? Do you fight mould on concrete or brick? Moss on your roof? Do you fear the slippery algae on walkways? Or battle mould and mildew on your composite deck? We’ve got an easy solution for eliminating these issues without the use of elbow grease or harsh chemicals—Wet & Forget! Simply spray and walk away!

There’s no scrubbing, no rinsing and no pressure washing! Wet & Forget remove moss, algae, lichen, mould or mildew gently over time, without damaging the surface being cleaned. Wet & Forget is ideal for roof cleaning, deck cleaning, the siding on the north side of the house that attracts mould and mildew and even mildew prone boats that need cleaning! While bleach and most commercial moss, mould and mildew removal products are caustic and can corrode and discolour many surfaces, Wet & Forget’s gentle, nearly pH-neutral formula is non-caustic and safe to use on any outdoor surface.

Because Wet & Forget’s gentle cleaning action uses the wind and rain to continue working overtime, it keeps ugly stains at bay for a year or more on most surfaces. So, while your neighbours get out the bleach or pressure washer, again and again, you can relax and enjoy your outdoor areas. All you need to remove algae, moss, lichen, mould and mildew is a garden sprayer and a bottle of Wet & Forget. No more dreading tough outdoor cleaning jobs—just spray and walk away, and let Wet & Forget do the work for you!
