I've also tried the bucket of hot water, but w/out dawn. You can see the oil creep up to the top of the bucket. Works like magic. After about 10 minutes, I remove the ball and take a sponge pad with a little dawn and clean the ball off. Tried this a couple of months ago as an experiment with most of my equipment. Pretty neat stuff.
I haven't tried Clean N' Dull in a bucket of water yet. As an experiment, why not put a couple of capfulls in the bucket of water and tell us how it goes? Good luck!
