Colder Weather’s Here! Can You Still Use Wet & Forget Outdoor?

There’s a chill in the air, and you’re busy with plans for the holidays. It seems like summer was over in a flash, and you didn’t get around to finishing all of your outdoor plans.

Was one of those plans to get rid of moss, algae, lichen, or mold and mildew on your deck, driveway, or other outdoor surfaces? It’s not too late!

Fall can be the perfect time to apply Wet & Forget Outdoor. Let Wet & Forget do the work for you, and get your home ready for next year’s barbecues while you eat this year’s turkey and pumpkin pie. Read on to find out how!

Why Fall is the Perfect Time to Apply Wet & Forget Outdoor

It’s normal to move your life more indoors this time of year, but that doesn’t mean that Wet & Forget can’t still clean up outdoors. That’s because Wet & Forget Outdoor works with autumn’s wind and rain to get rid of moss, green algae, black algae, lichen, mold and mildew on outdoor surfaces.

Even if you live in an area that experiences snow and sub-freezing temperatures during the winter, the Wet & Forget Outdoor that you apply now will still be there beneath the snow, ready to keep working during periodic thaws.

Better yet: Applying Wet & Forget now will give it lots of time to defeat ugly stains and get your home ready for next summer’s outdoor fun.


The Right Conditions for Applying Wet & Forget Outdoor

Wet & Forget Outdoor isn’t one of those high-maintenance cleaners that require you to scrub, rinse, and jump through other hoops to get rid of ugly outdoor growths. To apply Wet & Forget Outdoor, all you need are a pump-up garden sprayer, a dry, snow-free surface, and 4 to 5 hours for the Wet & Forget to dry thoroughly before the threat of rain, snow, or freezing temperatures.

Even chillier parts of the country such as the Midwest still see plenty of days this time of year when temperatures spend a few hours above the freezing mark. When the conditions are right, just spray and walk away, and let Wet & Forget Outdoor do the work for you!

To Defeat Ugly Stains, Just Spray and Forget!

Applying Wet & Forget Outdoor couldn’t be easier. To defeat outdoor mold and mildew, black or green algae, lichen, or moss, simply:

  1. Mix 1 part Wet & Forget Outdoor with 5 parts water in a pump-up garden sprayer.
  2. Spray the affected surface with the diluted Wet & Forget Outdoor at a time when the surface is dry and free of snow, and the temperature is above 32 degrees Fahrenheit. Allow 4 to 5 hours’ drying time before the threat of rain, snow or temperatures below freezing.
  3. Get back to spending time with family and friends, and let Wet & Forget Outdoor do all the work for you!

To kill moss, saturate the moss thoroughly in order to allow Wet & Forget Outdoor to reach the moss’s root-like structures. To remove lichen, follow these special instructions.

    Does Costco still sell this product? That was where I first saw it a couple of years ago and it seemed to still be in the store this summer but the “store locater” no longer lists Costco.

      Hi Al,

      Costco does sell Wet & Forget, though in most locations we’re a seasonal product. You’ll be able to find Wet & Forget back at most Costco stores in January.
