Trim strips
Metal trim needs special care.
For environmenta l reasons, Audi fabricates
the bright trim strips and trim pieces from
pure chromium-free aluminum.
Dirt and marks on the trim strips should be
removed with a
pH-balanced
cleaning agent
(do not use a chrome cleaner). Authorized Au-
di dealers carry clean ing products which have
been tested for use on your vehicle and are
not harmful to the environment .
To avoid corros ion on the exterior trim str ips,
only a pH-balanced solution should be used
for the windshield washer .
