To clean the surfaces of interior revolving glass doors, warm water is sufficient. Please use a sponge or a soft, lint-free cloth for this purpose. Clean over a large area and not selectively.
If any remaining dirt such as fingerprints is still visible on the revolving door, you can also use commercially available glass cleaners (foam cleaners). Please do not use any abrasive, corrosive, acidic or alkaline cleaning agents. They attack the glass surface and can thus be the cause of scratches. You can wipe excess water dry with a microfibre cloth. If glass is in contact with water for a longer period of time, stubborn limescale residues can form.
With laminated glass doors, make sure that the edge seal does not come into contact with water, otherwise moisture and the cleaning agent can penetrate the laminate.
Please do not use any scratching tools, razor blades or scrapers. They can leave visible and irreparable scratch marks on the surface.
