Cleaning the panel
Always clean the whole surface of the glass or ceramic, not partially.
Cleaning must be performed while the glass is wet.
After the application of cleaning agent, use a soft, clean, non-fraying
cotton cloth.
Do not apply any great pressure when carrying out the cleaning itself, as
this could cause scratches or smudges to appear on the surface of the
glass.
Wipe the glass in this way until the cleaning agent dries up evenly. The
more even the wet surface is, the lower the risk of smudging.
Never use pressure to wipe the glass dry. If smudges appear on the glass
anyway, please repeat the procedure.
The glass panel must be protected against aggressive substances such
as lime, soda, cement, etc., and must not come into contact with any
kind of paint or varnish.
All products containing hydrofluoric acids or fluoride derivatives are
prohibited as they may damage the coating and surface of the glass.
Do not use abrasive or aggressive cleaning agents for any cleaning work.
Always use pH-neutral cleaners, as strongly acidic or alkaline cleaners
can attack the surface coatings.
The metal version with the structured surface can be cleaned with a soft
brush.
