To clean brick pavers, use a pressure washer or a hose with a nozzle to remove dirt, moss and mildew. For tougher stains, apply a solution of bleach and water, and scrub the bricks with a bristle brush.
- Clean the bricks regularly
On a regular basis, sweep the patio, or hose off any dirt and debris. For light cleaning, use a basic dish detergent with a bristle brush to remove minor stains.
- Power wash the pavers
For mildew, mold or moss stains, use a pressure washer. If you do not have a pressure washer, use a hose with a nozzle to clean the brick pavers. Since brick is easily damaged, do not use a tightly-focused hose nozzle or exceed a pressure of 3,000 PSI with a pressure washer.
- Remove stubborn stains
If moss or mold stains remain after cleaning with a pressure washer or hose, apply a 10 percent solution of bleach in water. When cleaning with bleach, protect yourself, and wear gloves and goggles. Scrub the stains with a synthetic or natural bristle brush, and rinse with water. Before cleaning the entire patio, test a small area to see if the bleach changes the color of the bricks. Check the test area after a week before proceeding.
