I've heard sodium hydroxide concentrated to the extent of being a paste works exceptionally well, although I've never tried it and it sounds like an awful procedure

brazing cleaning paste should work nicely, you'd be amazed what this kind of paste or liquid could remove (some things plumber see around or inside pipes can be really worse than wire lacker, having 2 plumbers in my family I can say )

I would be careful with NaOH, it has a tendency to spit and fume if it gets in contact with some metals. If you decide to try this WEAR GOGGLES ideally a full face mask and gloves.

it's easier with the new 'lead-free' solder (mainly tin) with soldering iron at about 400C, than with the old 60:40 lead/tin solder. Hold/clamp the wire about 30mm from the end, make a nice straight cut at the end, unwrap about 1cm of outer insulation, gently twist the wire bunch a little tight, apply the iron to the end of the bunch with a little solder, as the wire heats you apply more solder. The fumes aren't good for you. some of the insulation 'caramelises', when cool scrape it off and I like a short length of heatshrink to hide the messy bit. don't hold the wire in your fingers as a lot of heat is required.. Ideally you would have flux and a solder pot
a simple candle flame is what I did. Only if you hold it too long, it gets too hot to hold or gets black. I noticed that solder also melts/burns it off. maybe acetone can remove it. if you have nail polish remover in your house, try it... I am not sure though... with steel wool or cotton it may come off...

Hey guys,
I need some help with litz wire once again because I'm using it for my high current primary tank circuit in my SGTC for the high frequencies. I've tried using a lighter and candle, both highly unsuccessful with the solder only adhering to the parts that aren't soot covered.me
I tried using some acetone but to no avail. I need to make my TC rather soon (in the next few weeks) and more importantly the litz wire connections have to be done within a couple of days.
I might get a solder bath for future use, but for now do you guys have any recommendations for an effective easy method at the moment?

you can splay out the end like a fan and lay it on a hard flat surface, use the sharp edge of a knife vertically to scrape one side of enamel, turn the fan over and scrape again, no need to completely strip the insulation off each strand, twist the end back into a round shape, the solder will now 'wet' the copper, have good thermal contact and the rest of the insulation should melt off.
