Brake Dust- do cleaners strip wax?

[Ferguson]

After trying to avoid using brakes and finding dragging my foot out the side was not really a viable option....

When I had a Mercedes, I lived with it by heavy coats of Carnuba wax.

I see a number of products aimed at breaking loose the dust so it rinses off, including of course one from BMW.

Do these products strip the wax?

It's easier to scrub off with just soap than it is to reapply a good coat of wax each time.

By the way -- this new X5 (sport, 19" wheels) seems MUCH worse than my old Mercedes SLK was. Or maybe I do not really remember. Or is it that the brakes are really new (still in first 400 miles). Does it improve any over time?

I avoided the whole warranty/rotors/fade/no-issues debate with the SLK by just living with it. Probably will here (it stops VERY well with stock pads). But it sure is a pain.
