What works best on brake dust?

your subject is about treating your dashboard but then you ask about brake dust?
well i use the interior protectant from BMW which i get from the dealer.
for brake dust, i needed to use PoorBoys Spray & Rinse to get the stains and nasty brake dust off, and then i polished and sealed my rims with Klasse All-In-One and sealed with Klasse Sealant Glaze, now i can clean my filthy rims with just a rag.

Good advice... i do the same with my wheel details... Any further info on the interior protectant from BMW? How much is it?

Clearkote Quik Shine

im not sure how much the interior spray costs individually, because it came in my bmw convertible top care kit. You can find it in the parts department at your dealer tho. Its really nice stuff, puts a nice natural shine on my dash and doors. I can look at the price for you tomarrow when i go to work.
