Every Pet-Owner's Problem: Getting Pet Urine Out of Carpet
There are a few sites online that advise the use of a vinegar and water solution to get pet urine stains out of carpet. While that may work to get the stain out, the Humane Society warns that the strong odor of vinegar may "encourage your pet to reinforce the urine scent mark in that area."
Other sites suggest you rent a steam cleaner to clean the carpet. Wrong again! "The heat will permanently set the stain and the odor by bonding the protein into any man-made fibers," informs the Humane Society.
So what should you do? If the stains are old, your best bet is to call a reputable professional carpet cleaner. If you don't know a good carpet cleaner in St Paul, we suggest St. Paul's Best Carpet Cleaners.
