This Bissell Pet Stain & Odour Remover uses enzyme action to target and eliminate tough stains and odours. It permanently removes urine stains and is an important first step when it comes to spot cleaning and carpet cleaning. It is specifically designed to provide thorough cleaning for organic stains like pet accidents or spilled food, and can be used on carpet, upholstery and other water-safe surfaces. Stubborn pet stains and unpleasant odours such as urine, faeces, blood and vomit are removed by the enzyme action, leaving a clean surface and fresh scent. For the best cleaning results remove as much of the stain matter as possible before applying Bissell Pet Stain & Odour Remover, and after applying leave it covered with a moist towel for up to 12 hours.
