I'm the proud owner of a KoAloha Concert ukulele. Over the past year, the satin/matte finish on the soundboard, particularly the area next to soundhole where I usually rest my little finger when fingerpicking, has started to go glossy/shiny. I understand this is due to a combination of finger oils and friction (I do tend to have oily skin). My question is can this finish be restored to its original satin finish? It looks weird having this gloss area on an otherwise matte finish. Should I just chalk it up to normal wear and learn to live with it?
