If you live in a climate where exterior stone walls get dirty quickly, there are a few things you can do to clean them more quickly.

  1. Use a pressure washer. This will quickly remove dirt, dust, and debris from the surface.
  2. Use a garden hose with a high-pressure nozzle. This will blast the surface with water to loosen dirt and grime.
  3. Use a broom and bucket to scrub the surface clean. Be sure to use plenty of water to help wash away any residue left behind by cleaning agents. ..
