Clean Mouse Droppings in Vent and Furnace

[RV-Newbie-101]

Hi all,

I had a mouse problem a few months ago. Went through the whole "seal the entire side of the trailer" and "black every access point" process, and no signs of mice for a while now. The one thing I forgot about while cleaning up the trailer was the furnace ducting. So I scoped it this weekend, and sadly, I found a few droppings in one of the duct runs and in the furnace. I want to clean and sanitize the ducts and furnace. Opening up the furnace to spray and clean it seems fairly straightforward, but I have no idea how to clean and sanitize the ductwork. The ducts are under the floor, and the underbelly has the thermal package.

Does anyone know the best way to sanitize and clean the furnace ducts?


Thanks in advance!
