When you clean your interior glass, it is enough to clean the surface with warm water. For this, use a sponge or a soft, lint-free cloth. Clean a large area, rather than pointedly.
In case of residues such as fingerprints on the glass door, you can additionally 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 cause scratches. You can wipe excess water dry with a microfibre cloth. If water acts on the glass door for a longer period of time, stubborn limescale residues may form.
For LSG doors, observe that the edge composite must not get into contact with water, since this may cause moisture and cleaning agent to enter the laminate.
