soft cloth or brush. Do not leave the soapy water on the surface for more than 5 minutes.
 Clean the surface very thoroughly and make sure that no soap residue remains on the surface.
 Then dry by wiping off the surface with a soft cloth.
DO NOT USE:
 Any cleaning device that might cause mechanical damage to the surface such as hard
brushes, high-pressure washers, etc.

Any cleaning agents (scouring agents or scrubbing powder), which will damage the surface;

Strong alkaline cleaning agents.
 Acid cleaning agents.
 Solvent based cleaning agents (e. g. based on ester, ketone, ether, furan or benzol).
