A damp cloth? just the neck and the area where the sound hole thing is, just to get fingerprints and stuff off can't take pictures with a dirty uke! So I was just wondering if a damp cloth would be fine, then wipe off the water with a dry cloth.
If you wouldn't clean your instrument with a 2x4, don't clean it with tissues, paper towels, etc. It's all just mashed wood fibers. Microfiber cloths are about a buck each in bulk and won't scratch.
honestly - buy some decent guitar polish - if you love your Uke dearly, the bottles dont cost a great deal, and a little goes a long way.
That said - I am either lazy, or a lover of the "lived in look". I have never polished any of my 5 guitars or 5 Ukuleles (or my banjo, or my mando) - I like the idea of patina and wear and tear building up - every nick scratch or ding on my instruments has a story behind it!
