wheels)
5-7
The following information is for standard Alcoa forged aluminum wheels without
the Dura-Bright ® surface treatment. See section 5-8, page 37 for specific instructions
on the care and clearing of Alcoa Dura-Bright ® surface treated wheels.
1. Clean frequently with high pressure water from a hose. The use of a mild detergent
will speed the cleaning process. Use no harsh alkaline cleaners.
2 . When tires are removed the entire wheel must be cleaned and inspected. (See Section
2, page 5). With a wire brush, remove any foreign products from the tire side of the rim.
Do not use a wire brush to remove dirt and corrosion products from the appearance
surface of the wheel. Generously coat the entire air chamber surface with an approved
surface protectant and lubricant each time the tire is removed (See 3-1, page 18).
3. To maintain the original appearance of your Alcoa wheels, the following procedures
are recommended:
a. After installing new wheels and prior to operating your vehicle, use a sponge, cloth
or soft fiber brush to wash exposed wheel surfaces with a mild detergent and warm
water solution.
b. Rinse thoroughly with clean water.
c. Wipe dry to avoid water spots.
d. Wax the cleaned surface with Alcoa Advanced Aluminum Care System Polish
or Simonize, Mothers, California Gold paste wax, No. 7 Car Wax or equivalent.
e. Clean your Alcoa truck wheels as frequently as required to maintain their appearance.

1. Clean frequently with high-pressure water from a hose. The use of a mild detergent
will speed the cleaning process. Do not clean with abrasives, abrasive brushes, steel
wool, scouring pads or strong chemicals, such as acids or lye-based products. Never
spray cold water on extremely hot wheels. Always allow time to cool before cleaning.
2. When tires are removed, the entire rim must be cleaned and inspected (see
section 2, page 5). With a brush, remove any foreign products from the tire side of the
rim (portion of the wheel that supports the tire). Do not use an abrasive brush to remove
dirt, corrosion or other foreign products from the Dura-Bright
®
wheel surfaces.
Generously coat the entire air chamber surface with an approved surface protectant
and lubricate each time the tire is removed (see 3-1, page 18 of the Alcoa Wheel
Service Manual, July 2002).
3. To maintain the original appearance of your Alcoa Dura-Bright ® wheels, the following
procedures are recommended:
a. After installing new wheels and prior to operating your vehicle, use a sponge or cloth
to wash exposed wheels surfaces with a mild detergent and warm water. Do not use
abrasives, abrasive brushes, steel wool, scouring pads or strong chemicals (such as
acids or lye-based products). Standard off-the-shelf car wash and wheel detergents
are sufficient. Warm water and a mild detergent will speed the cleaning process.
b. Rinse thoroughly with clean water.
