Didn’t get around to cleaning the grill at the end of last summer (I usually try to do it once every year or two), and we were treated to a conflagration last night. Actually the fire was relatively small, but thick black smoke was just billowing out — enough to result in neighbors running over to see if everything was OK. Which got me wondering: How often do most people deep-clean their grills? I don’t mean “wire brush the surface” — I mean remove all the pieces and get down and dirty, scraping the Flavorizer bars, catch basin, etc. Or do you just let it burn off from time to time? If you answer, please also leave a comment guesstimating how often your grill gets used.
