Buyer of my gas grills Outdoorchef Perth me has pointed my "BBQ coach," that the best cleanses these cooking grates with a brass brush (steel brushes are not suitable here). First I looked at the brush Silvy bought with interchangeable brush heads (short and sweet:. The brass parts of a letdown seemed to melt like plastic). So buy 2nd chance for Outdoorchef and this Triangle brush. And with this, I am completely satisfied. Prior to cooking brush the rust and after grilling again (while the grill for 5 minutes while heated still "full speed" after removal of the food and then cleaned with this brush the hot grill grate). Fits comfortably in your hand and the bristle arrangement ensures a perfect result. In addition, this triangle design facilitates cleaning at all points of the grill. I do not know why: both from the same house, but the Triangle brush delivers by far the better result and moreover at a lower price. Therefore, full 5 stars. Supplement regarding steel / brass brush:'m not a physicist, chemist, etc. - only: brass is much softer than steel and therefore material gentler on the grill.
