The finish on the top on my Martin has lost its gloss where my arm comes over when I play. I suspect it's sweat and chemicals reacting with the lacquer that's caused it, so please don't explain that to me - it's not easy to wipe it with a warm damp cloth every time you play in a pub packed to the rafters with drunken folkies!

But can anyone tell me if it's possible to restore it and, if so, how do I go about it. Come on you axe-tecs, help me here!
