The other day I noticed that my SUV is a bit smelly - a combination of mare pee from a blanket that was in there, a faint whiff of cat pee (how?) and the mustiness of turning on heaters that haven’t been used in 9 months. Hmm.
Then a quart of vetrolin fell over and spilled in the back and wow! My car smells great! No need to clean it now
Other horsey smells I love: fly spray, Venice turpentine, fresh hay, good quality leather.
