[Amps] Removing enamel insulation?

[Bob Maser]

On the flip side of the coin,  I have some Formvar coated wire that is at 
least 15-20 years old and I find that if I try to wind it into a diameter 
smaller than 1" it cracks the formvar coating.  Is there any thing that I 
can do to this wire to recondition or soften it up?  I don't really think 
that it hurts unless I am trying to wind a tightly spaced coil but it still 
looks like s--t.
