GRIFFWERK recommends the "GRIFFWERK Care Spray", which is specially designed for our products, to care for and maintain the value of your stainless steel door handles and fittings. It cleans intensively, has a dirt-repellent effect and thus maintains the value of your stainless steel room door set, door handles and door fittings. Please do not use any aggressive cleaning agents or 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 under extraordinary stress, for example by building dirt, grinding dust, aggressive vapors or salt water. For this reason, clean the handle set with GRIFFWERK Care Spray immediately after soiling. Our GRIFFWERK care spray is available from all our trade partners.
