I was about to put 3 racks of ribs out on the smoker for dinner and I found a rat nest and a single, big, fat rat in there. I pulled the racks from the smoker and put them on my propane grill and have it going full blast. I removed the nest and the droppings and then sprayed the inside of the smoker with oven cleaner. Is there anything else i should do to clean this up? It's a natural gas smoker, so it doesn't get much over 250°F.
