I am new to the forum but have been detailing my vehicles with a PC random orbital and other polishes and waxes for 10+ years. I have tried some of the Adam's products and they seem to be top notch compared to many of the other products available. I have a 2018 Sierra Denali with the 22in wheels that have chrome plastic inserts. Unfortunately it seems that the insert side that faces the direction of rotation is getting brake dust build up. I have tried car wash soap and simple green at 1:2 ratio but the brake dust remains. Any suggestions for an appropriate cleaner? The inserts are ridiculously expensive so I want to be conservative with the cleaner and I think if I can take care of it now before it gets too much build up I should be good. Thank you-
