I just bought my truck and started cleaning it. Pulled the back seats down and found a ton of dog hair with urine stains on the back seats. needless to say it smells and I don't know what will work best to get rid of the stink. Thanks.
take it to someone who has a carpet extractor/shampooer, you are going to need a deep clean to get those urine stains and smells out, i use steam for my detailing business, it kills bacteria that causes the smell and sanitizes the area.
if it was the summer time i would just say leave the windows open as much as you could...i often get fish smell in my truck because of the amount of fishing i do...but leaving the windows open usually does the trick..that and an air freshener!
