So I know a lot of you know I am new to the grill/smoker experience...which is good. I like to stay green so I can grow. Well, I would say I have smoked maybe 3 times since my gift in mid-January, and grilled a dozen. Here is my process...which yes, leads to a question. Just skip down if you want to cut through all this: When I smoke, I put a little bit of charcoal briquettes in the side stack, soak them in lighter fluid and after they are all nice and hot, put on my wood. I then put back on the two racks that fit above the wood, but beneath the lid (like cooking grills). When I grill, I stack a nice triangular shape of wood charcoal, saturate with lighter fluid, let sit 3 minutes or so, light...let stand for about 15-20 minutes to get the fluid off, even out, put the grill racks over, and grill. Today I noticed when grilling that the black surface underneath my grill was crumbling away. Just the black...leaving the nice metal surface underneath unprotected. And btw, it happened just tonight, but about 8" in diameter. I have a feeling it is from saturating the charcoal, and then it burning off directly on the bottom of the grill (and yes, i have a drip pan thing underneath where the charcoal goes...I guess it just runs out). Have I ruined my grill for long term keep? Is this normal? Does my grill just really suck that much? Is my process wrong? I swear, I want to know EVERYTHING!
