Most of us have heard of using spit to clean the rim. I myself don't care to much of that practice. I was just now sitting here claeaning a few of my pipe stems with brebbia stem polish and noticed the tube said " pipe and stem polish". I used it on the rim and it did a nice job of cleaning it. You have to rub it in for a bit then wipe clean and buff with a clean towel. It does a much better job than spit in my opinion. Just a little friendly advice.
