Stripping magnet wire? You mean like after making coils and wanting to
solder them to something? Why bother? Just put a blob of solder on
your iron's tip and put the end of the magnet wire into the solder blob.
After several seconds, the insulation will melt off and the wire end
will be tinned with solder and ready for install!

This is only true for some types- like Belden Soldereze. Many others will


not be touched by heat- formvar for example.

I usually just take a piece of 120-400 grit sandpaper, fold it in half
and pull the wire through it. Several passes usually is enough.


Thanks for the comment on the old, tried-and-true chemical-less
way. Finishing sandpaper (dark grey abrasive surface) will work
on 36 gauge old-style enamel covered wire, also on 25 gauge
(rare, surplus from transformer winder) Teflon covered. Takes a
bit of practice and "feel" to keep from abrading too much of the
copper on the very small gauges. :-)

I use the little squares of finishing grit paper cut into four smaller
pieces, each of those folded in two. Lightly holding the fold-over,
a couple passes over the wire end is all that is needed.

On the suggestions by others -

"Soldereze" and "Thermaleze" wire would strip just by soldering
iron heating of the copper right at the cut...but still needs some
abrading after starting the melt sometimes. I've used that, but
ran out. In winding toroids by hand, that kind tends to expose
the copper in places unseen except by high magnification. For
that former the old enamel type seems to be the sturdiest (with
exception of rare and way-over-expensive Teflon-covered). In my
experience that includes Kynar covered wire-wrap type...others'
mileage may vary.

"Zip Strip" (methylene chloride) is an unknown here, including the
supplier. [no supplier source posted]

The old GC "Strip-X" was the best for quick one-of-a-kind coil
winding. It was definitely acidic by odor and reaction to some
other materials...would have some enamel "lifting" action within
ten seconds of application. Alas, my father-in-law, a polymer
chemist, passed on a quarter century ago and cannot help with
expert advice on this. :-(

The search for a quick stripper (of wire) goes on...perhaps aided
by "inductive reasoning?" :-) Thanks again to all for replying.
