Allow the solution to remain for 15 minutes before rinsing, and examine the area for color changes. If no changes occur, water the plants nearby plants thoroughly, and dampen the deck with plain water.

While the deck is still damp, use a broom or mop to apply the bleach solution. After 15 minutes, rinse the deck using a garden hose. Direct the runoff into a sanitary sewer to prevent the cleaning solution from damaging plants or entering nearby water systems.
