Thanks for the kind words, gents.
Fallguy: I soak the blades overnight, clean them off, and then repeat about three or four times. However, sometimes I speed up the process by hooking the blade up to the positive terminal of a 6V or 12V lantern battery with an alligator clip, and then hooking the negative end up to a piece of scrap steel slightly submerged in the vinegar. With this method I let it go for a few hours, clean it off, then repeat three or four times. Hope that helps.
