If you have pets, you know accidents happen. Unfortunately, some pets are more prone to accidents than others. Enzyme stain removal solutions are effective, but they can get expensive if you have a pet who has regular accidents. Instead of purchasing pricey brand-name cleaners, try a homemade enzyme cleaner to remove urine stains from your carpet. Chances are, the ingredient is already in your kitchen cupboard and it won't cost you a dime.
