The natural appearance of NextStone products are maintained with little effort. 
Although NextStone products will get dirty, like anything exposed to the atmosphere, a 
heavy rain or a simple washing with a garden hose will do wonders. If additional 
cleaning is required the following steps outline the recommended cleaning procedure. 
Step 1 
Any liquid soap or a light spray of simple green or the equivalent, followed by light 
brushing with a soft bristle brush will work with our product. NextStone recommends 
using whatever product you choose on a small area first, to check for color 
fastness. You can either use a soft bristle brush with a garden hose or a 
pressure washer. If you use a pressure washer, be SURE not to get closer 
than 12 inches and not more than 1500 PSI.  
Step 2 
For mildew we recommend the cleaning solution X-90.  It is very effective in removing 
mildew from vinyl siding, and will work on our product. It would be prudent to test a 
small area first with any new product.
