Ok, followed the directions, did the dry burn thing, and got the big chunks of gunk off of the coil (well, most of it anyways, didn't want to break the col scraping too much), but even after rinsing in warm water several times, using an ultrasonic toothbrush to clean, I am still getting a nasty taste in the coil. tastes just like the stuff on the coil smelled during dry burn to remove. nasty. is soaking it in vodka the way to go here? also, is there anything besides a dry burn to remove the burned on gunk from the coil? does anything out there "de-gunk" it by soaking? thanks in advance.
