After 25 years of Poly guitars I've got my first guitar which is nitro. A very nice Made in Japan Strat. I have a polish for the finish which is suitable for nitro, it's by a company called Music Nomad. So I'm OK with that. What I do from time to time is put a little Dunlop 65 Lemon Oil on a rosewood fretboard then wipe it off with a cloth. I done that to this guitar for the first time but I'm a little worried now. If I got a little lemon oil on the nitro would it damage it? I wiped the finish down with a different cloth after doing the fretboard. Should it be OK? Will this be OK to do in future or should I avoid the lemon oil getting anywhere near the finish?
