Hey, I'm wondering how people clean their smokers.. I have a gmg pellet grill and it has a sliding tray. I do not put tin foil over that because I like being able to control the smoke/heat with it. I always scrape the tray best I can and scrape everything else I can but there is still grease that I can either wash off or burn off. I usually will just put the temperature to 500 and burn all the grease and hope it doesn't catch fire. What are your tips/advice??
