Buyer beware. There are so many pet odor removal products on the market and many of them just do not work. However, there are a few that work extremely well. Professional Carpet Cleaners across North America have had amazing results with products like Grease Magic's Pet Stain & Odor Remover. As it states right on the label, it is People Safe, Plant Safe and Pet Safe. The pH of the product is 7 (neutral) so it is safe for use on most carpets and does not damage hard wood floors. It is important to note that urine often soaks below the carpet into and sometimes past the pad into the subfloor. This makes removal more difficult for a home owner to do well themselves. Professional Carpet Cleaning firms often use deep flushing equipment to flush urine salts and residues from the carpet and pad.
