The reason that I ask, is that I cleaned mine out for the first time the other day. I have put nearly 100 pounds of WW's through it and noticed some crud around the edge. After draining the pot, and letting it cool, I added some hot soapy water and it cleaned right up. My boolits are looking a lot nicer now as well. I was starting to notice impurities in my boolits. They look great now.
