I use a Weber gas grill. I have a smoker box and preheat to the point of smoke coming out of the box. Then however, when I turn down the heat to a lower temperature, the smoke generally disappears until I turn the grill on high afterwards to clean the grate. Tonight we were treated to the great smell of smoke while we ate and the grill was sitting empty with the setting on high...
Also, I have the cast iron grates which are nice, but I've never found a brush which fits between them to clean them as well as I'd like.
Any ideas on that?
