Stains on REAR wheel.

[crewzzn88]

Good Day! My rear wheel on my 08 R12R are getting " stain " from the brake pad dust. I tried simple green and it just removes the surface dust on the wheels. My front wheels dont seem to have this problem. Can anybody recommend a cleaner ?

A really good cleaner is a WD40. I know it's not primarily a cleaner, but it gets all kinds of stains. I used to use it with my chain driven bike when that chain lube gets on a rim. Of course after you use this "cleaner" you need to use some shampoo to get rid of WD40 but that's easy.
You should also take your rear brake caliper off and stretch it a bit. They get stuck after a while and that's why you get so much brake dust there.

My dirty back rim cleaned up with soap and water, as I recall. There hasn't been a build-up of pad dust since I cleaned up and lubed the caliper bolts 8K ago.
As far as cleanup, I find just about anything that won't yield to dish soap will be dispatched by paint thinner. And you won't have to clean up twice. Just buff with a clean cloth.
