Mud + s150 = ?

[superstator]

Anybody have any bright ideas for getting the mud out of a polar s150? I used mine during the Great Hillsboro Mudfest '07, and now the start button is dead. I took it apart, and the electronics are fine - the little compartment that the big red button sits in must just be full of silt preventing it from depressing completely.

Ideas?

Never mind, problem solved. I dunked it in a bowl of warm water for a few minutes, and then pushed the buttons while holding it underwater. First two pushes I got bubbles, then three or four big spurts of muddy water, and now everything's moving freely again. I'll let it dry out, reassemble, and I should be good as new(ish).
