For over 50 years Klenztone has been an industry leader in the development of masonry restoration products. Klenztone products do not contain corrosive acids or hydroxides, which means that they will not erode or “eat away” at the surface of the stone. This fact alone has made us the choice of thousands of restoration professionals worldwide. Along with restoration cleaners our product line offering includes every aspect of the restoration process from degreasers and grout cleaners to high performance sealers and strippers.
SAFER: Klenztone does not contain Hydrofluoric acid, Hydrochloric acid, Muriatic acid or Sodium Hydroxide as some other products do.

  Remember, NONE OF OUR PRODUCTS CONTAIN CORROSIVE ACIDS as many similar products in the restoration business do. The acids used in other products actually eat away the top layer of the surface. Besides destroying property, the surface will be left raw, exposed and damaged. The KLENZTONE approach is different. It works by penetrating the pores and releasing the trapped dirt inside. That way, after rinsing with water, the loosened grime washes off, leaving the original masonry surface clean, hard and intact.
