How to Clean Decorative Concrete
For routine cleaning of decorative concrete, simply use a hose and apply water to remove light dirt and debris. If you need to remove more set in dirt and staining, use mild detergent such as dish soap or even mild laundry detergent mixed with water.
In addition, you can use a smooth sponge or a mop to lightly scrub any stained areas. Never use any abrasive sponges or brushes as they can damage the concrete and deteriorate the patio sealer.
