Haven’t tried it yet–and I don’t need to in order to post a review, because this is the second one I’ve purchased (this one for our summer home and our little mini grill). The first one, hanging beside our big Weber, is still going strong after four years. The corners are thoroughly covered in bristles so I can get in between the gratings, and the brass slices away soot and buildup but has never damaged the porcelain surface (a stainless steel brush, on the other hand, did…which is why I now only use brass).
