Extremely gentle yet intensive care cleaner specially developed for surface-treated, impregnated and difficult-to-wet stone surfaces. Although impregnated and sealed surfaces rarely absorb dirt, stubborn dirt from bird droppings or other environmental influences makes cleaning essential. CleanPrince Terrace tile care cleaner - free of abrasives, chlorine and acids - cleans gently, yet intensively, without attacking the sensitive coatings. CleanPrince Terrace tile care cleaner can be used on Allen surface-treated, impregnated, sealed and difficult-to-wet stone surfaces, terrace areas, courtyards and paving areas, precisely where conventional cleaning products are ineffective due to the difficult-to-wet surface. Also ideal for refined natural stones such as marble or granite. Safety advice:.
