How to Clean White Landscape Rocks

White rocks gleam in the landscape, providing a clean, bright contrast to fresh greens and rich browns. White goes with anything -- but it also gets dirty easily, and this is as true in the garden as it for your clothes. And although you can't toss your white landscape rocks into the washing machine to brighten them up, you can reach for something else that might be on your laundry shelf, or in your kitchen, to help you clean them.

White rocks may grow moss in damp climates.

Large Rocks

Step 1

Sweep away any loose dirt with an outdoor broom.

Step 2

Pour full-strength household vinegar over moss and other small plants, if you want to remove them from the rock. Let it sit for at least five minutes.

Step 3

Scrub the dead moss and other small plants off of the rock with a stiff wire brush.

Step 4

Rinse the rock with a hose. Use a high-pressure nozzle for best results, or use a pressure washer, if you have one.

Step 5

Mix 3/4 cup of bleach with 1 gallon of water in a bucket, and use that solution to saturate any remaining moss or stains on the rock.

Step 6

Let the mixture sit for 10 minutes, and then use the scrub brush again. Rinse with the hose or pressure washer and let dry.

Small Landscape Rocks

Step 1

Hose the rocks down to get rid of as much loose dirt and debris as possible.

Step 2

Scoop the rocks up with a shovel and dump them onto a gravel screen laid over a wheelbarrow or bucket.

Step 3

Hose the rocks down while they are on the screen, and then replace them in the flower bed.
