Nothing kills smells like ozone does. Back when i owned my dealership, i had bought a few suicide cars from police auctions. Still have a bit of parts in them, all the blood and stuff. Pull the interiors out, pressure wash them, put the ozone generator in it for a while. Had that new car smell back in no time…lol
People who say they can not get rid of an odor, have never been introduced to Ozone
