I have used this product. I have some brake dust deeply embedded in the paint of my white wheels. WheelWax is not as miraculous as the ad copy would have you believe. That area right at the base of the valve stem will NOT get perfectly clean! But, it DOES work better on my wheels than any other cleaner wax I have tried (Mother's, that came with a clay bar; and some Turtle Wax product). I hope, with spring weather and time to apply the elbow grease, I'll be able to bring these wheels back up to Autopia-grade clean.
Usually I don't care about the smell of a product, but this stuff has a strong artificial-coconut odor that I could do without. But I'll hold my nose for a bit, to get good results.
