Removing the coating on magnetic copper wire

Has anyone had any experience removing the clear coating that is used on copper wire used in relay coils and or transformers or electric motors?

 

I would like to do this without using any abrasives and also the wire I am hoping to do this with is .005" or 36 gauge.

Michael,

 

I believe they still use lacquer on those, Michael.   Is there a manufacturer's name available to you and/or the part number?  Might be able to get a spec sheet off the web.

Hi Mark,

This is what I have, it is old and I have no idea where I got it. I do know that i have had it for at least 40 years.

Paint stripper may work, also I have heard of burning it off. You'd have to be careful not to burn up that small a wire, though.

I would try soaking it in lacquer thinner and then clean with fine steelwool.  If this does not do the job repeat with acetone.

I've successfully used burning on copper wire - followed by a wiped with a rag to remove the residue - but you'd need to be careful of the heat on such fine wire.
