Hi Lee, I really should do a video on this. I can't recall your fingerboard. If it's maple it has a finish on it and only needs to be cleaned with a good quality guitar polish when you change your strings or if it gets dirt buildup on it. A few years back we developed a satin urethane finish for the back of the neck that only requires wiping down with a dry towel after playing and the occasional cleaning with guitar polish. The body doesn't require protection, just de-smudging to keep it looking nice. Guitar polish and a microfiber cloth is all you need. We've tested most of the polish brands out there. We prefer Martin polish.

Oops! Sorry, Sheldon. She's Z2 #4909 with a wenge fingerboard. The reason I'm asking is I downloaded a maintenance manual by Jerzy Drozd. He recommends tung oil for rosewood and ebony boards every six months as well as spirit of turpentine for deep cleaning. I love Jerzy's basses, but I thought it best to consult with you as wenge feels a bit more porous. Any thoughts? Thanks for the Martin guitar polish recommendation; Stuart Spector also recommended it for my departed NS-5 and I was pleased with the results. Peace, Lee

I recommend lemon oil for cleaning. Tung oil would be good once the board is clean but in my opinion not really necessary unless the board looks overly dried out. It's sticky and bleeds back from the pours for hours so is a bit of a pain to apply. Read up on fire safety before using any finishing oils.
