Good tips mate. Might I suggest that a saucer of water will do just as good a job, and is a lot safer. I've seen a mod immersed is liquid (beer) and it didn't end well. I've now started using a coil master coiling jig that has a wire brush on one end, to remove those stubborn bits of gunk, especially on claptons etc.
Nice vid. Didn't know about the water trick (always a bit wary with the batteries etc) but will definitely be giving that a go.
