Re: Cleaning the Hookah
I'm not a fan of using soap, only because it's a pain to get it completely rinsed off. I just use a mix of realemon lemon juice from a big bottle and water. This way if I don't get it all rinsed out, all I taste is a little bit of lemon. Plus, if I'm feeling frisky I'll leave a bit of lemon juice in the vase water for some extra tang.
I've never tried beer, and probably won't. Aside form fursaken's advice, it seems to me like a waste of a perfectly good beer.
