Yes, I found Frets.Com for the first time today on my Internet travels, spaw - it's a brilliant site. I think I'd make a point of checking Mudcat suggestions there before trying them out.

But there's a fair amount of know-how out of the cat I've always found.   It's just a matter of identifying it.

For cleaning a guitar I've found a damp teeshirt is better than a paper towel or a bog roll. I've been using an old one from the Cambridge Folk Festival years back that is no longer up for wearing. An honourable and relevant retirement for it. And an old toothbrush is handy too. I don't plan to use toothpaste though.
