I've seen a few solutions on Google. One says put it in a microwave for
5-10 sec. I have my doubts. No one confirmed it. Another was to put it
in very hot water, apparently in about 3-4" or so, but nothing more was
offered.

Anyone got a tried and true method?

(I just tried 10 min in hot water w/o any luck. Probably a real goner.)
