    Never bought any , I get so much of it free from many sources , problem is I do not know its properties .
    Scrapping and or very fine emery cloth , in that order has worked for me .

    I have a curved ceramic finishing tool that works wonderfully for scraping magnet wire.

    I just scrape it with an x-acto. Just don't press down very hard, and keep the knife moving. Holding it still on the wire is what causes nicks.

    Just installed three small cores using both 100W iron and scrapping with x-acto knife.
    Had better luck with scrapping, solder get the wire too stiff to mount and harder to control how close to the core it should be tinned. Works for me on #26.
    I'll try nail polish remover on next set.

    GC used to sell a stripper solvent you stuck the wire in and wiped it off. Acid based I assume.

    #10-2602 & 10-2616, "Strip-X", aka methylene chloride. IOW, paint stripper.

    I had a good luck removing paint from metal surface using household oven cleaner.
    But it took a while.

    The active ingredient in oven cleaner, also drain cleaner is sodium hydroxide, caustic soda, or lye (link). It also eats skin... it's nasty stuff.

    Methylene chloride is pretty nasty too... be careful if you use stuff like this. At least with lye, you can rinse it off and be fine.
