I built a 40x40x48 cedar smoker last year and it was awesome all summer. It did remain outside all winter and it does look like a red squirrel may have found a way in for a little while. Probably found a small crack in a block near the fire box? I am hoping someone on here can help me out in how to clean it and make it safe for smoking meat. I'm thinking just scrub it down good with a vinegar and water mixture and then smoke it out for a few times prior to placing meat back in there. Anyone have experience with this? or Suggestions are highly welcomed. I added a couple of pictures here. Thanks All for any help you can provide!
