A pet accident on the carpet creates an unhealthy environment in your home. The urine soaks into the carpet, the underlay and even the flooring so the mark visible on the carpet surface is a lot smaller than the actual area affected. As it dries the odour intensifies, especially in humid environments. General cleaning cannot remove this odour. Chem- Dry’s PURT (Pet Urine Removal Treatment) breaks apart the odour molecules and can assist with urine discoloration.
