For the cast iron grate of a Weber Q gas grill brush is a bad design. The stem springs, because you can not build up pressure, the bristles are too short and therefore not really come into the gaps of the grate and they are too soft and bend, the brush looks "ragged" from. In addition to the bristles of the whole lubricating freezes, it looks disgusting and does not go easily back out. The brush with a wooden handle is much better and cheaper!
