Guys, great ideas for wheels, but are you also taking about your solutions working on the discs behind them, and your ability to reach the discs with various cloths and fluids as the OP first said was the second part of the problem he was trying to solve? IMHO, MS wheels are fairly simple with a number of products and methods. What those fluids and methods then do temporarily to the discs behind the wheels and how easy or not it is to remove those stains before your next drive is the next part of the question I believe the OP was also trying to solve.
I'd personally appreciate any solutions you folks may have found that eliminates 100% of the temporary rust stains on the discs when you clean the wheels. I've not yet found any products or methods after a number of attempts. Thx in advance.
