But in the ranking of the mindless or bad accessory for Weber grills this brush comes after the aluminum drip bowls (which you can incidentally refolding in 30 seconds of tin foil) in second place.
The bristles suffer just too much and go quite quickly in the knee. Rather buy a real wire brush! If on the one hand effective and the bristles are much harder, accordingly, also the dirt comes off better. A cast-iron grate does not need a soft brush like this one.
