Anyone have any tips for the best way to clean the chimney and chute for the Masterbuilt Cold Smoking Kit? I use mine for everything now since it gives me better smoke and allows longer burn times, but it's pretty badly clogged up and the pellets and chips get stuck in the chute. I have to go out once in a while and use the BBQ spit to lightly poke through the suspended wood so it falls the rest of the way down. I tried using a screw driver and managed to get some to peel away, but there are enough rough edges that when the moisture kicks up, the pellets and/or chips stick to the sides. I thought about putting the chimney on the gas grill and cooking the crap out of it at high heat, but I'm not sure if that's a good idea. Anyone have any other suggestions? Is there some kind of cleaning solution I should try?
