Do not use cleaning solutions that contain hydrofluoric, oxalic and most other acids on chrome wheels (or any wheels).
If the customer is unsure of the chemical make-up of a particular wheel cleaner, it should be avoided.
For wheels showing signs of milky staining from acidic cleaners, refer to Customer Assistance and Instructions below.
Warranty of Stained Chrome Wheels
Stained wheels are not warrantable. Most acid based cleaners will permanently stain chrome wheels. Follow-up with dealers has confirmed that such
cleaners were used on wheels that were returned to the Warranty Parts Center (WPC). Any stained wheels received by the WPC will be charged back to
the dealership. To assist the customer, refer to Customer Assistance and Instructions below.
Pitting or Spotted Appearance of Chrome Wheels
Figure 2
A second type or staining or finish disturbance may result from road chemicals, such as calcium chloride used for dust control of unpaved roads. The
staining will look like small pitting (refer to Figure 2). This staining will usually be on the leading edges of each wheel spoke, but may be uniformly
distributed. If a vehicle must be operated under such conditions, the chrome wheels should be washed with mild soap and water and thoroughly rinsed as
soon as conveniently possible.
Important
Road chemicals, such as calcium chloride used for dust control of unpaved roads, can also stain chrome wheels. The staining will look like small
pitting. This staining will usually be on the leading edges of each wheel spoke. This is explained by the vehicle traveling in the forward direction
while being splashed by the road chemical. If a vehicle must be operated under such conditions, the chrome wheels should be washed with mild
soap and water and thoroughly rinsed as soon as conveniently possible.
Warranty of Pitted or Spotted Chrome Wheels
Wheels returned with pitting or spotting as a result of road chemicals may be replaced one time. Damage resulting from contact with these applied road
chemicals is corrosive to the wheels finish and may cause damage if the wheels are not kept clean.
Important
Notify the customer that this is a one time replacement. Please stress to the customer the vital importance of keeping the wheels clean if they are
operating the vehicle in an area that applies calcium chloride or other dust controlling chemicals! "GM of Canada" dealers require prior
approval by the District Manager - Customer Care and Service Process (DM-CCSP).
"Stardust" Corrosion of Chrome Wheels
Figure 3
A third type of finish disturbance results from prolonged exposure to brake dust and resultant penetration of brake dust through the chrome. As brakes
are applied hot particles of brake material are thrown off and tend to be forced through the leading edge of the wheel spoke windows by airflow. These
