Car rat protection
Air fresheners won't fix it. This will.
1
Musky = urine and a nest. Sweet and rotten = likely a dead rat.
2
The cabin air-filter housing, behind the glovebox, is the top suspect.
3
Disinfect first, then wipe and bag. Gloves and a mask, always.
4
New cabin filter, AC on fresh-air mode, windows open.
Rats come back to spots that worked. Make the engine bay unwelcoming.
