To clean outdoor waste receptacles, use powerful jets of water and soap along with a brush to remove any debris on the garbage can. To deodorize, use baking soda, bleach, borax, charcoal or a dryer sheet. After deodorizing, rinse the can with clean water.
Begin cleaning the waste receptacle by emptying it. Using a broom, remove any debris sticking to the garbage can. Then, wash the receptacle with soap or detergent, and hose water into it. Scrub the can with a brush with a long handle.
Baking soda, borax and bleach are antimicrobial agents that kill odor-causing microbes such as bacteria and fungi. To use baking soda, scrub it on the walls and floor of the waste receptacle.
When using bleach, dilute it in water, and pour the mixture in the receptacle. Similarly, if using borax, mix 1/4 to 1/8 cup of sodium borate with 1/2 gallon to 1 quart of hot water, and pour the mixture in the can. Allow these solutions to sit in the can for some time, and then drain them out in a plastic receptacle. Secure the lid on the container, and dispose of the solutions.
After rinsing the can, let it dry in the open air. Finally, sprinkle baking soda, layer charcoal or place new or used dryer sheets on its floor to absorb unpleasant odors when the waste receptacle is in use.
