Fabrics and fabric coverings
Fabrics and fabric coverings (e.g . seats, door trim pane ls, etc.)
shou ld be cleaned at regular intervals with a vacuum cleaner . This
removes surface dirt partic les which could become embedded in
t he fabric t hrough use. Steam clea ners shou ld not be used, because
the steam tends to push the dirt deeper into the fabric and lock it
there .
No rmal c leaning
Genera lly, we recommend using a soft sponge or a lint-free
microfiber cloth to the clean fabric . Brushes should on ly be used for
carpe t s and floor m ats, since other fabric su rfaces co uld be harmed
by brushes.
Norma l surface stains can be cleaned using a commercially avail -
able foam cleaner. Spread the foam on the surface of the fabric with
a soft sponge and work it in gent ly. Do not saturate the fabric . Then
pat the foam dry us ing absorbent, dry cloths (e.g. microfiber cloth)
and vacuum it after it has dried completely .
C leaning stains
Stains caused by beverages (e.g. coffee, fruit juice, etc.) can be
t reated with a m ild detergent so lution . Apply the detergent so lution
with a sponge. In the case of stubborn stains, a detergent paste can
be applied directly to the stain and worked into the fabric . After-
wards, use copious amounts of clean water to remove the
re m aining dete rgent . Apply the water w ith a damp cloth o r sponge
and pat the fabric dry with an absorbent, dry cloth .
Stains from chocolate or makeup should have detergent paste (e.g .
ox-ga ll soap) rubbed into them. Afterwards, remove the soap with
water (damp sponge) .
A lcoho l can be used to treat st ains from grease, oi l, lipst ick or a ba ll-
point pen . Melted grease or dye must be patted off using absorbent
ma t erial. It may be neces sary to retrea t the areas with det ergent
paste and water. _.,
