How to Use Bleach As Algaecide

Algae is a common concern for many homeowners, as it grows steadily on a variety of exterior surfaces. When the conditions are damp and shady, algae can quickly pop up and spread steadily You do not need a commercial algaecide to remove the algae effectively, though. In fact, with a household bleach solution, you can quickly spray the covered surface and prevent the algae's return in under 30 minutes of work.

Household bleach will fix your algae troubles.

Step 1

Spray surrounding shrubs and plants with water to protect them against the bleach application. You can further protect them by covering them with drop cloths.

Step 2

Mix one part household bleach with two parts water in a bucket. Incorporate thoroughly with a wood paint stir.

Step 3

Protect your hands with rubber gloves and then carefully pour the bleach and water mixture into the top of the pump sprayer.

Step 4

Prime the sprayer as directed in the user instructions and then hold the wand 4 to 6 inches away from the surface and coat it with the bleach solution.

Step 5

Wait 12 to 15 minutes for the bleach to break apart the algae. Scrub it thoroughly with a stiff nylon-bristle brush to remove.

Step 6

Rinse the surface free of the bleach and algae with a garden hose. You can also employ a power washer with a 40-degree fanned tip attachment.
