Add 2 cups of the bleach to two gallons of water. Pour in 1/4 cup of dish detergent and mix well until it suds. Use a broom or another large brush and cover entire deck. Scrub where there is stubborn dirt and grime and then rinse off.
Try a mix of 3 quarts water, 1 cup oxygen bleach and 3/4 cup of liquid dishwasher detergent. Apply to surface, brush with a stiff broom and leave for 10 to 15 minutes. Scrub then rinse.
