My ukulele has a mahogany body, and its appearance has become a bit dull. I don't want to use any oils or polishers that would harm the wood. Any ideas?
I like Renaissance Wax, myself. It's kind of expensive but seems to protect very well and it doesn't make matte finishes as glossy as some waxes do. If it's shiny it stays shiny, if it's matte it stays matte with just a hint of "glow."
