These were on internet. I like using baking soda (Fabreze gives me a major headache.) Probably the dryer sheets only cover up the smell, not remove it. Would turning off the fan in the car prevent the odor from getting into that system? And covering up the pile of compost with plastic completely?
"Instead of using pan of baking soda, sprinkle the carpet and the upholstery with a generous amount of baking soda (make sure the material is dry). Gently brush it all over to attain full coverage. Let it stand for a few hours to absorb the offending odor and then vacuum it all up.
Place one or two bowls of white vinegar in the car for a day or two (while it is parked). Vinegar removes odors.
To remove odors from your car, crumble newspaper and leave in the car. Also, put a bag of plain charcoal briquets in the car to absorb orders. Do not use the kind with lighter fluid on the briquets
End car odors
New-car smell gradually turned into that old-car stench? Tuck a new dryer fabric softener sheet under each car seat to counteract musty odors and cigarette smells"
