I've tried many ways to clean the inside of the wheels, Griot's long reach garage scrubbers have been the best so far. I took that as a "suggestion". When I reordered wheel scrubbers they seemed expensive but I decided to give it a try. I used them yesterday and I really, really liked them. Goes behind the spokes, cleans the rotor hub and even cleans the top of some (smaller) calipers.10 10 recommended
