Cleaning and Care
ATTENTION
Scratches on the panes due to improper cleaning
Rubbing the panes causes scratches.
f Dirt and dust particles must first be thoroughly rinsed
off with water. If necessary, only wash with water, a
pH-neutral household detergent and a soft, clean
cloth.
Clear water is sufficient for cleaning and care . Use
warm water together with a neutral, non-abrasive cleaning
agent (household detergent, pH value 7) if more heavily
soiled. To preserve the surface characteristics, regular
cleaning must be carried out at least every 3 months
(outside of door, seals). The slide area behind the side
seals must be kept permanently clean and able to slide.
A variety of environmental influences (e.g. maritime
climate, acids, road salt, air pollutants, paint damage) may
make additional protective coating necessary (see Paint
treatment on page 12).
