Using improper cleaners can lead to the death of the surrounding vegetation. Oxygen bleach will kill the algae without harming the brick, mortar or plant life.
Things You Will Need
-
Fill a 5-gallon bucket with warm water. Add powdered oxygen bleach at the rate directed on the package. Stir with a wooden stick or paint stirrer until the bleach dissolves.
-
Pour the bleach solution onto the brick. If you are cleaning a brick wall, dip a sponge into the solution and wipe down the brick until it is soaked. Let the bleach sit for 10 minutes.
-
Scrub the brick with a street broom or a stiff-bristle scrub brush until the algae is gone. Rinse the brick with a garden hose and let it air-dry.
The Drip Cap
- Algae and mildew can build up on brick over a winter season, or if the brick is exposed to moisture and shade.
- Algae discolors the brick and can make the surface look prematurely old.
- Stir with a wooden stick or paint stirrer until the bleach dissolves.
