Well, the palms of my hands seem to produce quite a lot of grease. Not so much that people try to avoid shaking hands with me, but the typical greenish goo is building up quickly on the wenge fretboard of my Thumb n/t. Cleaning this from a high gloss varnished fretboard is a quick and straitforward process, but I have found that the open poored wenge can make it slow and difficult. The grease-oxide-mix gets stuck in the poores and is virtually impossible to get out. I am rather affraid that the use of any solvents/cleaning products might damage the wood. So, someone knows any solvents or cleaning techniques that will make my life easier? Thanks, Marijn PS: no other complaints about the wenge though, it's an awesome neck wood!
