Mike! How are you? I think this would be a great thread for you to discuss meg's wheel brightener. Being that I detail many neglected wheels, I feel that I have yet to truly maximize the potential of this product. My partner has used it more than me and he always tells me that cleaning the wheel first with regular cleaner, and then spraying on the wheel brightener and letting it dwell for some time will greatly improve cleaning ability on severely caked-on brake dust (besides clay barring, which would take an unreasonable amount of time for most clients). Do you have any tips to fully maximize the potential of this product?
