Sorry if this subject has been covered before, but I can't find anything on it. I've had my CG Pro for a couple of years now, and the grease and stuff has built up on the inside of the cooking chamber and it's really a mess. I thought before the season starts, I'd clean it out and de-grease it. Is there a proper way to go about this? I was thinking about using some car engine de-greaser like "Gunk" and then a seasoning smoke afterward. Is that the right way to go?
