I found success. I just had to let it soak a little while in rubbing alcohol and it came off pretty easily. I like them much better this way. They still look about the same, although not shiny. When I first stripped them, they had kind of a dried-out, chalky white look, but after absorbing some oils from my hands, they look about like they did before.
My problem with the original set was that because they were sealed, there was no where for the sweat and oils from my hands to go, so they just got slippery. Now they absorb the sweat and oil and feel much better to me. That may ultimately cause them to rot or warp, but I shoot it with Hogues most of the time anyway.
