I know this sounds a bit silly but if you have a steam cleaner - you could try using that. Although saying that, I have a Labradorite wand that I once took in the bathroom and the steam/condensation weakened it and it snapped in half. However I glued it back together with super-strength glue and it's still quite strong but I suppose the glue negates some of the crystal's energy...I don't really know
