Step-by-step instructions: - Protect surrounding plants. Thoroughly saturate any nearby plants, shrubs, and grass with water before, during, and after cleaning to prevent damage. - Dilute the concentrate. Mix the cleaner with water according to the severity of the stains. - For light soils, mix 6 ounces of concentrate per 1 gallon of water. - For heavy soils, mix 12 ounces of concentrate per 1 gallon of water. -Apply the solution. Spray the diluted cleaner onto the surface with a pump sprayer. For tough stains, you can also use a mop or brush for application. - Scrub the surface. Use a deck brush or floor scrubbing machine to scrub the surface, helping the cleaner penetrate deep into the concrete's pores. - Let it sit. Allow the solution to work for no more than 10 minutes. Do not let the product dry on the surface, as this can cause staining. - Rinse thoroughly. Rinse the area completely with a garden hose or pressure washer. For older or larger stains, you may need to repeat the application.
