Hey fellas I have a custom offset smoker. Had it now for bout seven years. Inside seems to be flaking a little. Looks like a mix of sut, grease, (maybe some high heat paint too?). Was wondering best way to clean the pit out. Was gonna hit it with a pressure washer, try to towel dry it best I could then re-season it by burning some oak for a couple hrs. Good idea? Should I put high heat paint inside? Sounds weird to do so.
