    Acetone vs. WD40

    O.k., I could just try it out, but I guess somebody else has already done that: I usually use acetone to clean my surfaces before gluing/epoxying or applying a finish (in most cases a mix of tung oil and shellac). Can I also use WD40 for that? Will it affecy epoxy or oil-based finishes?

    Thanks,

    Stefan

    WD40 is evil stuff. The layers of build up over the years leaves a shelac like coating that is yellow and dingy. Granted I don't have input on your needs but after cleaning tools and equipment over the years treated with this gunk... I'll never touch the stuff again...

    I dunno. WD-40 comes in a handy can, whereas acetone is kind of aggressive and harder to apply. Depends on what you're using it for. I doubt it's "evil".

    Ingredients can be found here

    It's mostly mineral oil and alkanes so may impact any oil finish you apply

    WD-40 is good for removing glue residue from glass -- nothing else. It will bond close-fitting metal parts, remove many finishes and dissolve some plastics.
    If you reach the age of 60 without becoming a curmudgeon, you haven't been paying attention.

    WD-40 will leave a thin layer of oil on the pieces you are working on, preventing epoxy for sticking. Acetone is definitely the winner here. Acetone will dissolve the oils on some of the oilier hardwoods, where as WD will leave a film on top of it.

    Acetone and wd40 will leave a residue. I use acetone first then denatured alcohol to clean my stuff.

    +1 . Lately I've resorted to using WD40 to dissolve adhesives and to help remove rust. Like RR, I use acetone followed by denatured alcohol for 99% of cleaning applications.
