FAQ: Can I Clean my Awning with Wet & Forget Outdoor?

Wet & Forget Outdoor wipes out moss, algae, lichen, mold, and mildew on surfaces all around your home with no scrubbing, bleaching or pressure washing needed. Maybe you’ve enjoyed amazing results using Wet & Forget Outdoor to eliminate damaging moss on your roof, or disgusting algae on your deck.

But what about messes on your awning? Read on to find out about keeping your awning clean with Wet & Forget Outdoor.

You Love your Awning. You Don’t Love the Mold and Mildew.

Installing an awning is a wonderful way to enjoy some shade during the summer, and create a comfortable spot to relax. But whether your awning is aluminum, canvas, rigid, or retractable, it can fall victim to disgusting growths such as green algae, black algae, moss, lichen, or mold and mildew.

Cloth awnings can be particularly vulnerable to mold and mildew because the cloth can hold on to that little bit of moisture that creates the perfect environment for mold and mildew growth.

Pretty soon, you can find yourself spending less time relaxing beneath your awning, and more time up on a ladder with a scrub brush and bleach, or fighting with a pressure washer.

The Problem with Bleaching and Pressure Washing

Bleaching and pressure washing are two of the common methods that people turn to when they’re faced with outdoor growths such as moss, lichen, algae, or mold and mildew. But if you use bleach on your awning, you will either have to take it down to scrub it or climb around on a ladder and scrub the awning.

The caustic bleach runoff can kill patches of your lawn, and it can also damage or discolor cloth awnings or speed up wear and tear on the surface of some other types of awnings. A pressure washer makes a muddy mess, and pressure washing risks tearing cloth awnings and can add wear and tear to other awning types.

Neither of these methods does anything to prevent the growths from coming right back again, trapping you in an endless cycle of cleaning and re-cleaning. Worst of all, both bleaching and pressure washing leave your awning wet afterwards, which is like rolling out the welcome mat for mold and mildew to start re-growing.

How to Clean your Awning with Wet & Forget Outdoor

Cleaning your awning with Wet & Forget Outdoor couldn’t be easier.


  1. Mix 1 part Wet & Forget Outdoor with 5 parts water in a pump-up style garden sprayer.
  2. Spray your awning with the diluted Wet & Forget solution at a time that allows 4 to 5 hours’ drying time before the threat of rain. If your awning is retractable, leave it open for at least 4 to 5 hours to allow the Wet & Forget Outdoor to dry thoroughly.
  3. Get back to enjoying your awning, and let Wet & Forget Outdoor do all the work for you!

If your awning is retractable, leave it open as much as possible to allow Wet & Forget Outdoor to work with the wind and rain to eliminate the stains. Once the stains have disappeared, you can return to your normal routine.

When treating moss, be sure to saturate the moss thoroughly so that the Wet & Forget solution can penetrate the moss’s root-like structures. To treat lichen, follow these special instructions.

    We are about to store our Canvas awning in storage for the winter. Should I apply the wet and forget, let it dry, then store? Or should I keep it outside for a period of time after spraying and before storing?

    1. Wet And Forget

      Hi Susan,
      Great question! Your awning will need the action of the wind and the rain for all the dead growth and stains to be removed after applying Wet & Forget. If you put your awning right in storage, when you take it out it’s still going to have all the stains that weren’t removed. Keep your awning out and possibly periodically rinse the surface with water from a hose on a jet setting if you would like to speed up the process. Each time you do this it will act as the rain and help clean up the stains.
