when you talked about blowing all that out with an air hose, I could almost smell the mouse urine, I took nearly a small trash bags worth of Mouse fluff from a blower housing on a VW Bug engine once...you never forget that smell.
Definitely a smell that is never forgotten. My worst experience with mice was cleaning my great-grandparents house and sheds after they sat empty for 10+ years. Their nests were so big I could've lived in them!
I am more careful than I used to be. I blew everything out good and left the dusty mess till it settled overnight. I have heard a lot of bad stories about breathing that fluff and worse yet is coon feces.
