Use of cleaning materials that are not completely 100 % clean, can result in tiny microscopic signs of wear. These marks are more or less noticeable depending on colour and amount of light coming in to the area. These marks in no way reduce the practical value, but are unavoidable over the long term as with all high gloss surfaces on cars, glasses or other furniture surfaces.

Any stains – above all those from strongly coloured substances and liquids - are to be immediately cleaned with water, possibly adding standard household – non-scouring - cleaning agents, if necessary. Stains should not be allowed to begin drying. Stains, as well as spattered grease and grease deposits can be removed with a warm, mild soft soap solution.

When using conventional household cleaning agents, ensure that no undiluted and concentrated coloured cleaners are used, as the dyes contained therein could leave a residue.
