The Simonis X-1 tool will definitely help you out. It was designed for that cloth, and will pick up the chalk dust from your table. That's one of the main things I've heard about it is that you don't have the problem with your hands turning blue every time you play. Of course good habits like not chalking directly over the playing surface/rails will help as well.
If you're interested in an X-1, PM me. I have some in stock and ready to ship.
Edit...Oops! I just read your last reply again and saw that you already bought one...what do you think so far?
