Is it safe to use a sandblaster to clean my driveway?

It depends on the type of material you are using. Sandblasting is generally considered an acceptable method for cleaning hard surfaces such as concrete, brick, and stone. However, some materials may be more delicate and could be damaged by the abrasive action of the blaster. Before using a sandblaster, consult with your local building code authority to ensure that it is permitted in your area. Additionally, make sure to wear protective eyewear and clothing when using the sandblaster.
