Painted Surfaces
Wash painted surfaces frequently to remove grime and
caustic deposits which may stain the finish. See “Clean-
ing, Protection and Weather–Stripping” on page 225.
Chrome and Aluminum Surfaces
To prevent rust, keep chromed parts clean and protected
with wax at all times, especially in winter conditions where
the roads are salted.
• If necessary, use a commercial chrome cleaner to
remove light rust.
• Chrome surfaces are best cleaned with fresh water.
Wipe dry to preserve their luster. A commercial
chrome cleaner will remove light rust. After cleaning,
wax flat surfaces and apply a thin coat of rust preven-
tive lubricant around bolts or other fasteners.
• Clean aluminum wheels and bumpers with warm
water. Tar remover will get rid of heavy deposits of
road grime. To prevent spotting, wipe aluminum sur-
faces dry after washing.
• Under corrosive conditions, such as driving on salted
roads, clean aluminum parts with steam or high pres-
sure water from a hose. A mild soap solution will help.
Rinse thoroughly.
Stainless Steel
Even high quality stainless steel parts can rust under pro-
longed exposure to salt water, especially when the
salt-laden moisture is held against the metal surface by
road grime. It is, therefore, important to frequently clean
salty moisture and grime from stainless steel surfaces.
• If surface rust is encountered, wash the surface and
use a commercial polishing compound to clean off the
rust, followed by a coating of wax (do not apply wax to
hot parts, such as exhaust pipes).
• Never use steel wool when cleaning stainless steel
because minute particles of the steel wool can embed
in the surface of the stainless steel and cause rust
staining.
