Re the Chargone yes it does do a great job on rod type grates IF you have to patience to stand there scraping each rod. I'm very ADHD drives my wife nuts (probably why I always did so poorly in school and never went to college even though many people think I am very educated)
So the thought of standing over a grill the size of my Wolf scraping it bar by bar is not appealing

I like to crush, wipe and cook. Also it's not a good solution for the Q which is where the issue came up. I think the design and material of Q grates lend themselves to disasters of this type unless extreme care is taken, plus (though I don't have the tool anymore) I don't think it would fit between the wires on the Wolf due to the custom nature of the grates
