a couple years ago we left the windows down on our van and a cat peed in it. It was very strong. and our daughter smoked out in her garage and had a love seat out there and a cat got it. she left it for some time after that and when she decided to fix it it was saturated. We bought out spray at wal mart and is both cases soaked the items with the spray ( the love seat took 2 spray bottles.) She was able to put it back in the house andno smell. We still have the van and no smell. I hope wal mart still carries it for you.
