Hi,
I have a gaboon ebony fretboard on one of my basses, with gorgeous abalone block inlays. I'm wondering the best way to clean a couple smudges/grease spots off of it. Look like they may be from glue. I don't know. I put Gibson fretboard conditioner on it last night to keep it from drying up but wondering if there is anything I could apply first, to get rid of the smudges, without damaging the wood or inlays. Any suggestions appreciated

Thanks
