Re: Can't clean off baked on brake dust
Between three XFs and two Audis (one with two sets of rims), I self-limit myself to a once a summer thorough cleaning of all the rims. They are removed, sprayed with Hot Rims All-wheel cleaner, then washed off with a good dishwasher detergent to cut any grease. I have used a polishing compound on the inside to get them good and clean.. and smooth them out so dirt is less likely to stick. Final activity is to apply 2-3 coats of car wax to the inside and 1-2 to the outside. I find this allows future brake dust and dirt to wash off easily and lasts for about a year.
