My casting pot is a Lee model and I believe it is not the quality of others but, it needs a good cleaning. I followed directions given by Dragonheart in a sticky and everything seemed to be going well except….I cannot get the pour hole to open up. I let the solution sit in it for an hour but no success. What to do? Will just leaving the solution in it eventually clear it? I wondered if turning the unit on would melt it out? Ideas?
