Bought a electric smoke hollow 7 years ago and used it once due to the fact that I didn't know what I was doing and meat did not turn out . I thought it was the smokers fault so I never used it again. Before storing it away for a long sleep I cleaned it with oven cleaner. I since pulled it out and decided to do a little reading and I found out you should never use oven cleaner inside a electric smoker because of the insulation. So I took it apart to clean it really well and noticed that the bottom of the insulation was saturated with oven spray. should I cut 4 inches up around the bottom of the smoker to remove the bad insulation. Or should I call it a loss and throw the whole thing out.
