Mag wire

Ok, so I got another transformer rapped and I don't want to heat up the wire to burn off the Varnish.
I thought ok before I solder the wires to the pins, I can scrape the wires with a razor or sandpaper.
But what about finger nail polish remover or Lacquer thinner?
How do you do it?

Short of mechanical scraping, one of the effective ways is to use Acetylsalicylic Acid (yes an Aspirin tablet). Lay the end of the coated wire on an aspirin tablet and touch it with the sodering iron tip. It will disolve the coating and will be ready for soldering.
Caution; try not to inhale the resulting fumes though.

I have used this method on various wires for some time and other than the smell, it really works.
