Quoted from ForceFlow:No, I would certainly not recommend that.
Remove the board from the game. Hold it over a garbage can withe the compoet side facing down. Clip the legs of the battery holder and let it drop.
Anything else and you're just spreading the leaking material everywhere. The key is not to disturb the material that has leaked.
[Edit] nevermind, guess I was a little late to the party.
you do NOT throw batterys in the garbage can....
