Al,
I was using Turtle Wax 2001 wheel cleaner, an auto product for awhile. it removes the brake dust and most of the grime.
But none of the "spray and rinse" products get all the dirt and gunk off, that includes the S100, and other miracle cleaners.... you still have to dry them off after use and you will find a lot of grime on your rag/towel when you do that.
I've been using those products for "between washes" duty, but when it comes time to spend some time, I use the Meguiar's Quik Detailer and old tube socks.
I put the bike up on the lift, slip a tube sock over my arm, and spray the detailer on the sock. I can then get between the spokes with my fingers and as the sock gets grungy I just pull it down a bit and start with a clean surface.
If you really want those wheels to shine you gotta get up close and personal....
