Back in the days of the gas grill if I wanted to clean the grill off I would simply forget to turn the gas off and the grill would burn the "leftovers" off. Then I would not grill again until the propane tank was filled. Obviously, if I can get the BGE to 700 degrees I should be able to do the same faster. Unfortunately, I noticed from a previous post that they had sierred their grill permanently closed by running the temp up for prolonged times.[p]So any suggestions?
