GRIFFWERK recommends using special stainless steel care sprays to care for and maintain the value of your stainless steel door handles and fittings. They clean intensively, have a dirt-repellent effect and thus maintain the value of your stainless steel door set, lever handles and door fittings. Please do not use any aggressive cleaning and scouring agents containing alcohol for cleaning - regardless of whether the stainless steel surface is matt, polished or shiny. Please note that the surface of the lever handle set can be damaged if it is exposed to unusual stresses, such as building dirt, sanding dust, aggressive vapors or salt water. Therefore, clean the lever handle set with a stainless steel care spray immediately after soiling.
