Can CanyonRock™ be stained if used on a fireplace or another area prone to smoke rain damage?
Potentially, yes (just like natural stone or brick). To decrease staining, you can use a sealant on the area subject to the most smoke. To help remove stains, clean with mild detergent and nylon or plastic bristled brush. DO NOT use a metal-bristled brush or acid cleaners as they may damage the surface.
