The natural appearance of NextStone™ products are maintained with little effort. Although NextStone™ products will get dirty as with any product exposed to the elements, a heavy rain or a simple washing with a garden hose will clean the product well. If additional cleaning is required, the following steps outline recommended cleaning procedures.
Step 1
A mild dish soap followed by light brushing with a soft bristle brush will work with the NextStone™ product. NextStone™ recommends using whatever product chosen on a small area first to check for color fastness. Use a soft bristle brush with a garden hose or a pressure washer. If using a pressure washer, be SURE not to get closer than 12 inches and not more than 1500 PSI.
Step 2
Although NextStone™ products are not susceptible to mildew, we recommend using solution X-90. It is very effective in removing mildew from vinyl siding and will work on the NextStone™ products. It would be prudent to test a small area first with any new product.
