We have dealt with this on occasion with our cars. We use this product in our house to help with pet odor and after cooking with garlic, onions and such. My mother in law had a sewer backup happen at her house, We cleaned up removed the carpet, ventilated and ran this for a few cycles and you would never know it happened. Works like a champ!
