Well I usually just leave it and let the grease build up but I have some little things I want to do to the cooker before winter. I hate working on anything that is greasy and this thing is so gunked up I dont take it apart anymore.....seriously I had to really whack it to get it apart for cleaning. I used a preasure washer.....big mistake, Now i am greasy and ashy instead of the cooker. Anyone else have a better way to do this? In case you are wondering I caved and got some technology to help me maintain good temps in these sub zero freezing days again....Yes I swore I would never buy a pit minder but I have to get uninterupted sleep. 10 lashes for me for saying i would never get one then doing it anyway. Whats your technique for cleaning? Mine really wasnt a good idea, head to toe in ash, grease, and gunk.....yummy!
