We think this video shows you a great home remedy for removing pet stains from carpet. Remember before trying any home remedies test your carpet for color fastness to ensure you don't harm your carpet. Baking soda and vinegar are a powerful combination that works well on a lot of minor stains. If you find the stain quickly before it dries you have good chance of removing the stain before it sets in. However, larger or older stains might require a professional carpet cleaner to remove the stain and lingering odors. At Chem-Dry of Tampa FL we have a Pet stain removal system called Pet Urine Removal Treatment (P.U.R.T) and it does wonders on large set in pet stains that have offensive odors.
