copper wire insulation remover chemical

[tubetvr]

For DIY purpose this method works very well, it was used long time ago by professionals but I think there are better methods available now.

Pour a little denaturated alcohl in a cup. Heat the end of the wires in an open flame until the enamel burns off and then dip the end of the wires in the cup with alcohol. The result is completely clean copper ends tha are very easy to solder on.

This method works very well for all size of wires, even for as thin as 0.1mm but then you have to be quick when you dip the wires otherwise they cool too much.

There is one risk with this method and that is that the alcohol catch fire but it is not very dangerous and easy to put out by covering the cup or even use water. There are no nasty chemicals involved and there is no risk of damaging the wire as it is if you use a knife.
