My board looks a iittle thirsty and I want to give it a light oiling and then change the strings tomorrow morning. Trouble is I'm all out of linseed oil and I don't have any commercial fingerboard oil either (not that I like fossil oil based lubricants on the board anyhow).
So, all I have is what's in the cooking cupboard; olive oil, sunflower oil and rice bran oil. Is any of this stuff safe or useful on a fretboard? It's a Les Paul and I guess we're talking about rosewood here.
