GM has looked for ways customers may improve the appearance of wheels damaged by acidiccleaners. The following product and procedure has been found to dramatically improvethe appearance of stained wheels. For wheels that have milky stains caused by acidiccleaners try the following:
Notice:THE 3M CHROME AND METAL POLISH REQUIRED FOR THIS PROCEDURE IS AN EXTREMELY AGGRESSIVEPOLISH/CLEANER. THE WHEELS MUST BE CLEANED BEFORE APPLICATION TO AVOID SCRATCHINGTHE WHEEL SURFACE. THIS PRODUCT WILL REDUCE THE THICKNESS OF THE CHROME PLATING ONTHE WHEEL AND IF USED INCORRECTLY OR EXCESSIVELY MAY REMOVE THE CHROME PLATING ALLTOGETHER, EXPOSING A LESS BRIGHT AND BRASSY COLORED SUB-LAYER. FOLLOW INSTRUCTIONSEXACTLY.Wash the wheels with vigorously with soap and water. This step will clean and mayreduce wheel staining. Flood all areas of the wheel with water to rinse.Dry the wheels completely.
Notice:Begin with a small section of the wheel and with light pressure buff off polish andexamine results. ONLY apply and rub with sufficient force and time to remove enoughstaining that you are satisfied with the results. Some wheels may be stained to theextent that you may only achieve a 50% improvement while others may be able to berestored to the original lustre. IN ALL CASES, only apply until the resultsare satisfactory.Apply 3M Chrome and Metal Polish #39527* with a clean terry cloth towel. As you applythe polish, the staining will be diminished.When dry, buff off the polish with a clean portion of the towel.Repeat application of the 3M Chrome and Metal Polish until satisfied with the results.If continued applications fail to improve the appearance further discontinue use.
This procedure will improve the appearance of the wheels and may, with repeated applications,restore the finish dramatically. For wheels that exhibit spotting from road chemicalsthe above procedure may marginally improve the condition but will not restore thefinish or remove the pitting. In this type of staining the wheel finish has actuallybeen removed in spots and no manner of cleaning will restore the finish.
