I have an electric guitar, and its fingerboard in is rough shape after years of barely touching it and being lent to my younger brother (big mistake). I unfortunately don’t have an instrument shop close, so I would have to order oil for it, and even the closest one only carries like 1 or 2 kinds of string kits and a few arranger keyboards, not cleaning products.

While I probably could get mineral oil (not at the moment of writing this, due to weekends), I’m wondering how well cooking oil would work. Tried some grapeseed oil on some other piece of wood, where it wouldn’t be a problem.

NOTE: Likely will go with the mineral oil, so I also have something to clean strings with.
