Just cleaned some white Gottlieb flippers with Goof Off, the stuff that strips paint and melts plastics. Came out great. Had the flipper bats out of the machine, and used small pieces of cloth dampened with the solvent. Got all the black gunk out of the ridges on the top of the flipper, and took off the rubber residue from the sides. EDIT: Test it on an inconspicuous spot. Would not try Goof Off on any flippers with painted accents or decals & would hesitate to use it on translucent flippers.
All the while I'm thinking that I should just buy new flippers, since cleaning them is tedious and time consuming.
Has anyone used an ultrasonic cleaner for the flippers?
