Cleaning fitting mats?

[Steerjock4009]

Tried cleaning my fitting mats to all the glue and paint off, but a can't get it off. I've used Hair Savor and Hocus Pocus. Doesn't cut it. Any help is appreciated.

Have you tried greased lightning?  Letting it soak and power washing it off?

EZ All scrub in with a brush. Rinse and scruff again with soap and water.
