Biodegradable degreasers that are safe for landscaping do not contain acids, petroleum distillates, caustics or volatile organic compounds that harm the environment. The degreasers contain only beneficial microbes that break down oil, dust, dirt and debris on concrete surfaces and remove the substances. Biodegradable degreasers also do not leave behind any chemical residue.
Apply the degreaser according to the directions on the chemical’s container. Mix the recommended amount of degreaser with the recommended amount of water. Stir the mixture thoroughly with a long-handled spoon or wooden paint stirrer. Spray the concrete you want to clean with water and pour the mixture on the surface. Scrub the concrete with a long-handled scrub brush or push broom. Rinse the surface thoroughly with water to remove the degreaser and debris.
Biodegradable degreasers will not harm your skin, but the chemicals will burn your eyes. Wear safety goggles, latex gloves and shoes when using the degreaser to keep the chemical and any debris out of your eyes and off your hands and feet. Follow all recommendations on the biodegradable degreaser’s container.
Biodegradable degreasers are available at hardware, home improvement and outdoor equipment supply stores. The chemicals are also available from chemical supply and concrete supply stores as well as online hardware and chemical outlets. The degreasers vary in price and packaging.
