There is a solvent. A local company uses it to remove the enamel from wires in a transformer ( lead out wires).
It doesn't say what the chemical is. It however has a warning on it about being dangerous if it enters the eyes.The bottle is locally made and I couldn't find out what it is made up of.
I will try to find out from the chemicals market one of these days.
My contact in the company has moved away and so I can't access the place again. It's great for thin wires.

I think it might be Methylene Chloride.

Safety: EP7771 vapors are heavier than air and will collect in low or unventilated areas. Use respiratory protection in those situations. Use face shield for eye protection and do not wear contact lenses.
Skin contact sometimes results in a stinging sensation; use solvent resistant gloves. EP7771 should be handled with respect, where adequate ventilation, personal protective gear is used and personal hygiene is practiced. See MSDS.
It boils at just under 40 deg C .

From the safety blurb it is obvious that it is a dangerous chemical to handle. If you have kids and family around you it is safer not to use such things.

Try to burn away the enamel with a small molten solder pot ------- a far safer way of doing it. It may not be too difficult to make one with some heating element from an electric iron and a small thin steel tube. You can work out the details.
Cheers.

Methylene Chloride is available in the US as "Zip-Strip" -- it's nasty, but not terribly so -- I can guarantee this, however, it will remove the color from Corian -- learned this the hard way when some dripped onto a bathroom sink.

I always just melted it off with the iron. Heat the cut end and apply liberal amounts of solder, the heat and flux work their magic and you don't lose any copper. Smells a bit though and is a bit tough on the tip.
