Spaw, you're a vewwy bad widdle kiddy.

I used a small amount of lanolin on mine and haven't needed to do it again, I wouldn't us Guiness or any drink as the sugar and stuff might eat away at it, or make it smell funky at the very least!

I pretty much beat the heck out of mine, using it as an native american drum and sound effects for songs. I almost never mute it, which would probably make me unwelcome at a celtic jam. I sometimes pour a small amount of water inside to loosen it, but it's tricky-too much and it only thuds. I like the idea of a spray and will run right out and get one!
