Cleaning Chrome and Aluminum Parts
Wash chrome and aluminum parts with a mild detergent. Do not
use steel wool, abrasive cleaners, fuel or strong detergents.
Cleaning Plastic Parts
Some of your vehicle's exterior trim parts are plastic. Clean with
a tar and road oil remover if necessary. Use a vinyl cleaner
for routine cleaning.
Do not clean plastic parts with thinners, solvents or
petroleum-based cleaners.
If you have your vehicle rustproofed, remove oversprayed
rustproofing with a tar and road oil remover. If rustproofing is
not removed from plastic and rubber parts, it can cause
deterioration.
Cleaning the Exterior Lamps
Do not use dry paper towel, chemical solvents or abrasive
cleaners to clean the lamps, as these may cause scratches or crack
the lamps.
Cleaning the Wheels
Wash the wheels with the same detergent you use to wash your
vehicle's body. Do not use acid-based wheel cleaners, steel
wool, abrasives, fuel, or strong detergents. These substances will
damage protective coatings. Use tar and road oil remover to
remove grease and tar.
If you have whitewall tires that are difficult to clean with regular
detergent, use whitewall tire cleaner. Follow the directions on
the container and rinse the tires with plenty of clean water.
NOTE: Before going to a car wash, find out if the brushes are
abrasive.
