I am wondering how often and how clean you guys keep your smokers? I have the attached a picture of my model. I place aluminum tins in the bottom of the smoking chamber to collect the drippings, as then it is easier to clean. This is a solid iron smoker...do I need to be worried about the drippings? Do I need to clean it each time after use, or do you let it go for a while? I am mainly curious, cuz I had a simple gas grill, I didnt clean well, and it ended with a short life, and I want to take care of my new baby as best I can. Would be very interested to hear how often you guys cleam em and how intensely.
