Rules for furniture surfaces
• Clean wooden furniture finishes with a moist
cloth or sponge.
• Rub dry with a soft, dust-free cloth.
• Use mild furniture polish.
Do not use scouring solvents or inten-
sive cleaners since these can scratch
the surface!
Rules for cleaning the toilet area
• Clean with neutral liquid soap and a non-
scouring cloth.
• Do not use a vinegar concentrate to clean the
toilet and the water system or to decalcify the
water system. Vinegar concentrate can dam-
age gaskets or parts of the system.
• The rubber seals of the toilet should be cleaned
regularly with plain water and a lubricant for
seals (not Vaseline or any other vegetable
fats) should be applied. Applying this regularly
to the washer of the valve and other seals in
the toilet will ensure that they stay flexible and
function longer.
Do not use scouring cleaners in the
toilet area either!
Do not pour corrosive cleaners down
the drain. Do not pour boiling water
down the drain. Corrosive cleaners
and boiling water will damage the
drainpipes and siphon traps.
Rules for cleaning the sink
• Only clean the sink with typical household
cleaners or special stainless steel cleaners.
The following applies for built-in equipment:
• Heating: remove all of the dust that has coll-
ected on the heat exchanger, base plate and
fan wheel of the hot-air system at least once a
year before the camper season begins. Clean
the fan wheel carefully with a brush or small
scrubber.
• The glycol mixture in the hot-water heating
system should be replaced every two years,
because certain properties such as protection
against corrosion deteriorate.
