CocheseUGA- Heh heh, believe me, *I* wish I got the same results as other people... in a whole lot of different situations

Sure would make my life a lot easier!
Funny you don't notice soiling on your tires though, especially with your dusty brake pads. The soft summer-only tires on the S8 are especially bad, can't scrub them too hard or the rubber mars.
But oddly enough the MPV is the worst by far. I put some aftermarket pads on it (Hawks, IIRC) and while they were an *amazing* upgrade over the oe pads (no longer replacing rotors on a regular basis, among other improvements) they make a *ton* of pinkish/brown dust, worse than any of my German sports cars ever did. Using ONR on those wheels is what originally got my attention regarding the subsequent cleanups.
