I've used four methods: - melt with a soldering iron - burn off with a small butane torch - scrape off with some very fine grit sandpaper - scrape off with a single edge razor blade
All work, but I typically use the sandpaper or the razor blade. With sandpaper, I just double over the sandpaper over the end of the wire, squeeze, and pull the wire out. Sometimes takes 2-3 times to get it clean. With the razor method, I hold the wire down on the workbench and carefully scrape off the insulation, scraping toward the end of the wire. I find this gives me the best control of exactly how much insulation I remove. I just reposition the wire a couple times to get it all off. takes seconds, and is not hard on the wire (provided you have a light touch). Have wound many toroids successfully with all methods.
