Greg,
You piqued my interest with the Chargon. While I am more than happy with my Tool Wizard Toolwiz grille brush I would like to clean all-around my SS grates.
I have looked at the Billy Bar, Martin Grill Gadget, GrillFloss, as well as several others.
What caught my attention was that you have the same grates as I do, the SS rcplanebuyer 9mm which are fantastic.
Do have have enough room between the bars to get a good cleaning with the Chargon? What exactly makes it better cleaner than the others you have tried?
Jeff
