The manual states:
"Aluminum is susceptible to deterioration caused by salt and other road contaminants. Use a sponge and mild detergent to wipe away promptly. Be careful not to use harsh chemicals (including some commercial wheel cleaners) or a stiff brush. They can damage the clear coat of the aluminum alloy wheels that helps keep the aluminum from corroding and tarnishing."
I like to use Sonax on my wheels (once or twice a year) to really clean them up - I wonder if they consider that a "harsh chemical" ??
