Don't use wheel cleaning spray.
Over time, it will fade out the clearcoat,
and might even damage the paint.
I highly suggest getting a wheel brush with
soft brissles to wash your wheels when you
wash your car.
The wheel cleaners don't work on dust that's
been on for more than 4 days. I've tried all
of them, and the caked on dust will NOT come
off with just a wheel cleaner.
If you still want to get the cleaner, I
suggest Castrol Super Clean wheel cleaner,
and Westley's Wheel cleaner (cheap, and works
good on fresh dust).
