For new construction clean-up, you can't beat new Brick Clean! Formerly called Pro BRC, this STRONG acid-based cleaner is fast on mortar and concrete splashes and is perfect for tool clean-up. Works better and faster than acid alone on any masonry surface.
Using plain acids like muriatic will attack the surface without loosening the dirt. This cleaner has a surfactant that provides the advantage of "lifting" the soil or concrete splash from the surface with little scrubbing or blasting. Extremely fast when applied through a pressure washer.
For rust stains on driveways, do the general driveway cleaning first with Concrete Cleaner. Then apply Brick Clean to the rusty areas and begin scrubbing or washing within minutes.
Powerful cleaner saves time and effort on any brick cleaning project. Works well for masonry building restoration. Attacks all minerals such as rust, calcium, lime, efflouresence, and red clay stains. Great for cleaning off the red clay "splash-up" found on buildings all over the southeast. Works with hot or cold water to renew masonry surfaces effectively and quickly. Concentrated, so it can be down-streamed through your pressure washer. One gallon makes 5, so it costs only about a penny per square foot to use.
