The body should be finished and there are products available for this. Your local music store or online retailers like strings and beyond usually have some choices. As for fretboard I have used regular mineral oil from drug store with success. Just avoid organic oils that you would use for cooking as their residue will go rancid.
Yes my initial thought was olive oil then I realized that wouldn't be a good idea and I also thought about mineral oil. when you say the body can be finished is that will an oil or some sort of polishing wax? I'll do some exploring around this; I'd like to see if I have something already available that would be suitable.
For the fretboard and untreated wood, lemon oil is recommended. Rosewood and ebony and walnut loves it in my experience. For the body, that all depends on what type of finish so you need to exercise some caution there.
Thank you for the recommendations. I'm not sure about the finish on the body, maybe I'll simply take a soft cloth and give it a gentle hand wipe/buffing so I don't damage the finish. When I took the strings off the bridge fell off (one piece no damage) so I'm going to simply put it back in it's position and let the strings hold it in place. That way whomever purchases it can repair the way they want it.
