Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
~
Wash the whee ls with a sponge or hose
brush every other week.
~
For deep cleaning afterwards, use only a
dedicated acid-free cast alloy wheel cleaner.
~
Rub a coat of
liquid
wax onto the rims every
t hree month. Be sure to reach and treat a ll
parts of the rim.
To preserve the decorat ive appearance of the
cast alloy whee ls, some special care is neces-
sary. In add it ion t o road d irt and sa lt, brake
dust is a lso cor ros ive. If left on for too long,
brake dus t ca n cause pitting.
Use only specia l acid-free cleaners formu lated
fo r a lloy rims. Safe products are available at
your author ized Audi dealer. Never leave the
cleane r on the rims longer than specif ied on
the label. If not rinsed off promptly, the acid
contained in some cleaners can attack the
threads on the whee l bolts.
Never use abras ive or metal polishing clean-
ing agents. If the protective coating has been
chipped, e .g. by kicked up road dirt, touch it
up as soon as possib le.
