Hope get pit wheel dust off chemically. Once the wheels are dust free as possible, a nice wax will go on. Snaking the roof drains worked.

I *only* recommend this as an absolute last resort, but if either Sonax or Meguiar's wheel brightener fail (I have both), the last ditch option is literally muriatic acid. You're taking a risk with your wheel finish, but it works. It did NOT damage the finish when I used it, but YMMV. (The risk goes up dramatically if the wheels have been refinished.)
