I just purchased a used WSM 18.5" off of craigslist here for 75 bucks.This is my first ever smoker. It looks in really good condition except for the door, but ill get to that later. What should I do now that i have this thing. The original owner hasnt anything to it, as far as modifications go. It has been seasoned. Should i clean this thing before i use it? if so then how do you recommend cleaning it? What should i do to it modification wise to make it as optimal as possible? I already know that i need to do something to the door because it looks warped, when latched there is a substantial gap around it. Anyways sorry for rambling, any help will be appreciated.
