I googled "What dissolves polyester enamel" and found this interesting advi= ce: "One more secret from good old Dr. Wavebourn: aspirin.

Subject: [EE] Magnet wire insulation stripping Back in August 2013, I enquired on the list as to what people use to strip = enamel from magnet wire. None of the suggestions back then worked out for m= e & happily for me the problem went away at the time. Sadly however, like a= ll problems that don't get definitively solved, this one has come back. I h= ave 2 cryogenic looms of 100um wire to strip & solder with 48 wires in tota= l. This wire is quite brittle (Niobium-Titanium). Mechanical scraping has n= ot proved a good option so far, nor has burning of the insulation (solder p= ot). Ideally I need a chemical stripper that is available in Europe. Chemical stripping is what I have used many years ago (Eccostrip from Emers= on & Cuming). That's no longer available here. Nor are any strippers contai= ning methylene chloride. I was looking at something called dip strip (https= ://www.eraser.com/products/replacement-parts/dip-strip/) which seems to req= uire a hot pot to use. However even this appears unavailable apart from the= US & Asia. In desperation I'm asking again in case anyone has since found a solution. = I have to admit that when my original requirement for this went away, I did= not follow up at the time.
