-Remove wheel from car
-Put on gloves and goggles, place wheel in ventilated area on cardboard to protect your floor (did mine on stone driveway)
-With wheel completely dry, spray the oven cleaner on all the rims surfaces (front and back), it will foam. Gently lay tire flat on its backside
-Let it sit for about 5 minutes
-Use a small soft nylon brush (toothbrush soft) to scrub all surfaces, won't take much pressure, just lots of motion to loosen the accumulated gunk. A hard nylon brush will scratch the paint
-Rinse complete wheel with water
A 16 oz can will do all four vibe wheels front and back with one even application. For about $3 did way better than $10 plus products that still left the rust.
Before cleaning, note the inner and back part of the rim:

After Cleaning, the deposits on the back of the rim are significantly reduced:

Now I have to take care of those rusting rotors and drums to prevent stained rims.
