A tip I got from a member on Tuco's forum worked. It worked even better then I thought it would. He told me to get some hardwood charcoal and crush it down to bean sized and fill the pot. I went to WallyWorld this past Sunday and bought a bag of 100% wood charcoal. Crushed it up and filled the pot. I turned it up to max and let it burn. After I dumped the ash my pot was completly clean. I worked the spout with a dental pick after it got really hot and it cleaned out all of the zinc that was clogging the spout. Worked the valve rod in the cavity and cleaned it. Pot is completly clean and I am again able to cast. This took several hours but it saved my pot. Long story actually but it worked and I have a working pot again.
