Mouse piss smell coming out of the air and heat vents.
Bought a car that sat for 2 years. When you turn on the heat or air mouse piss
smell coming out of vents, any ideas how to get rid of smell.
That is one of the worst smells other than a dead rat smell. I've had some fair amount of luck using some Nature's Miracle in a misting spray bottle and spray it into the fresh air intake with the blower on high and running through all the modes, keep spraying until you see come out the vents and defroster. I usually do it three times letting it soak at least an hour between applications. Now it's not an immediate cure cause it takes time for the enzymes to start working but usually in a week it's got it provided the urine isn't way deep in the system. When I had my shop and this was a common problem where I lived I only had 2 rigs that this didn't work. Note that when the enzymes start working the smell might get stronger for a day or two but then it's gone after that. Good Luck
