    Hi,

    I just picked up a 1940's National Guitar lap steel. With the exception of the tuner buttons, it's in great shape.

    The issue that I am trying to deal with is some sticker residue on the MOTS finish. I was thinking of using rubbing alcohol, but I was hoping that there might somebody with more experience than myself who could help me.

    Thanks,

    edg

    Don't know perzactly what you've got, but I ruined an old celluloid tort guard off an epi archtop bass with denatured alcohol. That said, I've got a newish MIM J bass with an aftermarket MOTS guard on it and I wipe it down with denatured from time to time for cleaning so there is definitely a big difference in what they are made of today versus way back when.

    Rubbing alcohol is not near as strong but unless you can get a replacement for the MOTS you are talking about, I'd proceed with much caution with any kind of alcohol.

    In Dan Erlewine's repair book he recommends naptha for cleaning old instruments. Might be worth googling his name to see if there's an article available online.

    And +1 to being cautious.

    Hi.

    If in doubt about what the finish/material may be, I always try cooking oil first.

    And I also always test any liquid on an invisible spot.

    Any solvent will most likely destroy any finish made before the 60's.

    IME anyway.

    Regards

    What do you use to get the oil off of it once it's clean?
