They're an integral part of your landscape, so not cleaning them up will affect the overall look of your landscaped outdoor space. Several cleaning methods can be used to clean rocks from the landscape, so select the one that best suits your situation.
Cleaning rock from a river requires a little more time than cleaning other types of garden rocks or stone covers.

A common reason for clearing landscape rocks is the belief that lichens should be removed from garden rocks.
Pressure washing is a less labor-intensive method for cleaning landscape rocks; however, you should be careful not to chip rocks in the process. If you need to clean your vertical rock work, you should first consult the contractor who applied the rock work or the manufacturer of your particular stone. Then simply sweep the leaves and give the decorative rocks a good look to see if you need to do more cleaning. If you take care of your things routinely, then it's easier to do the actual cleaning twice a year and have a happy, smiling landscape.
If you have masonry on the outside of your house, retaining walls, or pillars made of manufactured stone, it may be a little more difficult to clean. To effectively clean a dripping edge like this and returning it to its original state, the best option may be to simply start over. So, some areas may need a bit of cleaning and other new bags mixed in or on top to get that fresh brushed feeling. If your rocked area has been flooded with weeds, dirt, and silt, it is possible to deep clean the river rock.
