This powerful cleaner contains no bleach or ammonia, making it safe for people, pets, and plants. Application is simple: set the valve to the clean position and spray from top to bottom, allowing the product to work for 5 to 10 minutes. For rinsing, switch the valve to rinse and turn on the hose at full pressure. For heavily soiled areas, scrubbing with a bristle brush and a second application may be necessary. One gallon covers up to 4,000 square feet and can be applied using a pressure washer, pump-up sprayer, brush, or roller, while the 56-ounce bottle features a convenient hose-end attachment for easy use.
