If your home or yard features a stone retaining wall, you should familiarize yourself with how to go about cleaning it should the need arise. Fortunately, you'll be pleased to learn that this type of stone wall can be easily cleaned in a timely fashion.

Step 1—Spray Your Wall

The first step in cleaning your stone retaining wall is to thoroughly spray it down with a garden hose or pressure washer. If the wall features a normal amount of dirt and debris, a garden hose should serve as a sufficient spraying tool, whereas a pressure washer should be used to spray stone retaining walls that have accumulated an abnormal amount of caked-on filth or have not been cleaned in a very long time.

Step 2—Scrub Your Wall

Now that you've thoroughly sprayed down your stone retaining wall, it's time to remove any set-in stains or dirt deposits. To do this, use a hard-bristled scrub brush to firmly scrub away any stubborn stains that your initial rinsing failed to take care of. Once the wall is completely clean, give it one last vigorous rinsing to remove any remaining bits of filth that you may have missed.
