I have a propane Somky Mountain Series made by Great Outdoors. Got it at Walmart 2 years ago. Smoked probaly 15 turkeys in it, 50lbs or jerky and this or that here and there. I got reading on someones site the other day about creosote and cleaning regularly. Got me thinking, is there general maintance I should be doing to my unit? Do I need to rub the walls down on a regular basis? To me it has an oily seasoned surface, but I don't even know what creosote would look like? I only use chips from walmart and dunhams. I don't want to be poisioning my friends or family, so I thought I would run these questions by the forums..... Thanks for any help you can give this rookie.........
