What's this stain on rims? - ZR-1 Net Registry Forums

George Maz · 12-07-2017

Last week scored a nice set of OZ Racing Futura 18" wheels off a ZR-1, so I removed the '90 Saladshooter wheels and prepared them for storage. Removed pressure sensors and washed rims with 1/3 diluted wheel cleaner and gentle brush. Then a second wash with Green Soap Tincture and warm water, which is a fantastic degreaser. The fronts have a few stains, rears cleaned up nicely.
Any idea what caused this? Something leaking on to the rim? How best to gently clean?
