Wet & Forget removes moss, mould and mildew stains over time, without damaging the surface being cleaned. Wet & Forget is ideal for roof cleaning, deck cleaning and the north side of the house that attracts mould and mildew. 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 safe to use on any outdoor surface.

Because Wet & Forget's gentle cleaning action uses the wind and rain to continue working over time, 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 moss, 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!

Apply Wet & Forget Outdoor with a garden sprayer. Dilute 1 part Wet & Forget Outdoor to 5 parts water.


Apply Wet & Forget Outdoor to a dry surface in order to penetrate the stain completely. Saturate the surface completely with Wet & Forget Outdoor to remove moss, mould or mildew stains. For best results, apply Wet & Forget Outdoor on a cool dry day with no chance of rain for four to five hours after application. Morning or evening is best. This will ensure that the surface being treated stays wet for an extended period while Wet & Forget Outdoor begins breaking down the growth. Vertical surfaces that don't have good exposure to the elements might require some assistance using either a water hose or a light brushing. If an area is particularly bad, apply Wet & Forget again approximately one month after the first application.

After the stains have disappeared, use Wet & Forget Outdoor as a maintenance tool. Re-apply at the first sign of new growth to keep stains from coming back. No scrubbing necessary--just spray and forget it!

Treating Moss: To get rid of moss, completely saturate the moss making sure the Wet & Forget Outdoor soaks through and comes in contact with the surface the moss has attached itself to. Over the next few days or weeks, you’ll notice the moss turning brown, curling up and detaching from the surface. The wind and rain will help wash away any remaining moss.
