How do I clean my cedar smoker from being outside in a Michigan Winter?

[Jeremy Klosowski]

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!

Clean meat contact surfaces and Vac out any Squirrel debris, but that's it. Do you sanitize your Oven before each use? Do you scrub out the interior of your outdoor grill before you use it? Same here. The Smoker is an Oven covered in Antibacterial Smoke! You NEVER clean the walls unless they get moldy...JJ
