Not sure about this Tim but I have heard that denture cleaning tablets work great for things like this. At least I know it would not cause any damage on the glass bowl.
We don't have one close to me either but I wish we did. I have been to the one in Tucson several times when I have been visiting Roger there. Mike, I'm with you, Two Buck Chuck can't be beat.LOL
