Errmm, oops regarding Medium Ceramic Benchstone

Hi guys. I made a goof recently when I was cleaning my medium ceramic benchstone. I used some gunscrubber (1,1,1 tricloroethane) to clean the surface off, then before it was totally dry put it back into the plastic holder it came with. The gunscrubber did a job on the plastic and it seems to have seeped in the stone a little bit, it cuts very slow now and I find I have to wipe the surface off far more often to make it cut at all. I've tried using gunscrubber again to "undo" the effect but it's only resulted in marginal improvements. Any suggestions? I've thought about putting it into the oven at "broil" for a few hours to try to turn the left over plastic in the stone into carbon.

Thanks!!
 
I'm not sure you want to bake it to death. You'll likely end up with charcoal, which will still clog things up and be even harder to remove. Of course, if you somehow have access to an oxygen-rich atmosphere, it would be easy to turn the carbon into carbon dioxide, which would float away. Don't know what effect high temp and oxygen would have on a stone.

Have you tried soaking for a while in a large quantity of trichloroethane, or just wiping? After soaking, I'd try to rinse the stone with fresh solvent to wash away any dissolved plastic.

What kind of plastic is the holder?
 
I've only used the compressed triclor in a can of gunscrubber, aside from some other common solvents, havent tried soaking yet, I guess I'll do that before I try anything really wierd.
 
Could you melt out the plastic by holding the stone over an open flame??
Good luck.
