Wet & Forget Outdoor: Your Ideal Brick Cleaner

patio cleaner

Brick is a gorgeous, long-lasting material that adds value to your home. Whether your home itself is built of brick, or you have a brickwork patio, walkway or retaining wall, bricks can’t be beat for their beauty and durability.

But if your brickwork is covered in moss, lichen, algae, mold or mildew, it’s not so beautiful anymore. And the problem isn’t only cosmetic: some growths can actually scar your bricks.

While cleaning methods like bleach or a pressure washer are harsh and don’t last as long, Wet & Forget Outdoor‘s gentle action will free your bricks of ugly growths and keep them clean for a year or more in most cases.

Read on to learn about taking good care of your brickwork with Wet & Forget!

For all bricks:

Wet & Forget works on any color of brick, including red bricks. Check out the photo above to see the awesome results one homeowner got using Wet & Forget Outdoor to remove algae from his red brick patio. Thanks for the photo!

Wet & Forget Outdoor is ideal for painted bricks, too.

For algae, mold or mildew:

For large brick surfaces, connect the Wet & Forget Rapid Application to your hose and saturate the surface completely. For medium-sized surfaces, in a pump-up garden sprayer, mix 1 part Wet & Forget Concentrate with 5 parts water.

Thoroughly saturate the affected area at a time when the bricks will have 4 to 5 hours to dry before the chance of rain. Then relax, and let Wet & Forget do the work for you.

For moss:

Mix 1 part Wet & Forget with 5 parts water in a pump-up garden sprayer. For high elevations (such as large brick walls) we recommend using Wet & Forget Hose End to apply.

Spray the moss with Wet & Forget, allowing 4 to 5 hours to dry before the chance of rain. Be sure to soak the moss thoroughly, so the solution penetrates all the way through the moss.

For lichen:

Mix a solution of 1 part Wet & Forget and 5 parts water in a pump-up garden sprayer. Saturate the lichen with the solution, allowing 4 to 5 hours to dry before the chance of rain.

For higher up areas with lichen saturate the brick surface with the Wet & Forget Hose End Product. Wait 15 minutes, and then saturate the lichen a second time.

This second application allows Wet & Forget to penetrate the lichen’s multiple layers. It is best to treat lichen on a day that is not too hot and sunny, to avoid rapid evaporation and allow Wet & Forget the maximum time to penetrate the lichen.

  1. We have brick walk ways and sidewalks that are covered with something (i have no clue exactly what, though). The bricks are not only ugly now but also incredibly slippery when it rains. There have been a few close calls where someone almost got badly hurt from slipping.

    My bricks are held together with sand and not cement so i have never been able to pressure wash them. The task of hand-scrubbing them is daunting.

    How does wet & forget work on brick pavement filled with sand? How will it impact the sand? Will it erode it?

    If your product is safe to use on this type of pavement, which application would you recommend?

    Also, how do you determine how much to purchase?


    1. Hi Helen,
      Wet & Forget will be the perfect easy solution for cleaning up your bricks and removing the slick algae and mold. You’ll want to apply a good heavy amount with a garden pump sprayer when the bricks are dry and just leave it. Wet & Forget will not harm the sand or the surface. Wet & Forget comes in a few different sizes, you would be fine purchasing our smallest size (43oz) or if you buy a larger size, just know that Wet & Forget lasts forever and is good to use on pretty much any exterior surface green and black stuff grows on.

    1. Hey Ray,
      This photo is an application shot from using our product on a brick paver patio. We currently do not have an after photo as we haven’t revisited this area yet. However, if your patio looks similar to this, Wet & Forget will clean up any moss, mold, mildew, or algae growths and stains on the surface.
