[Amps] Removing enamel insulation?

[Mike Sawyer]

Back when I worked for EIT, I had to build detonators by hand. Essentially 
they were nothing more than a dc-dc amp with a boost. Anyhow, I used to use 
a chemical substance that was fairly high pH. I would dip the wire in it, 
wait about 10 seconds and wipe it off. It would make the enamel look like a 
gel. The one thing I do remember about it that if I got it on my skin, it 
would burn like the dickens. I think G-C made it. But this is going back 
about 25 years.

Does anyone have a good way to remove enamel (Formvar?) from thin wires?
Scraping/sanding works fine for large wires but doesn't work too well
for thin wires.

Is there a chemical that will do the job (dip/wipe)?

I'm looking to wind some small toroid transformers (receive/low power)
and need to strip the wires close to the core after I have would the
transformer.
