Sprayed aftermarket rims with wheel cleaner, got the rims clean but left the hub area where the tire bolts down ( especially in the rear) white looking after I cleaned off with water. Now when I clean the wheels, (no wheel cleaner) it turns rusty color, I can use a cloth to rub some of the rust off, but that's about all , Any ideas on how to get this off or some product out there for this? Need all the help I can get with this.
