Knockout Rapid Rescue is a powerful pro-biotic stain and odour remover. Its multi-purpose use is ideal for food spills and pet messes. It can be used on all surfaces and is ideal for use around the home, public buildings, hospitals and vehicles where stains and odours appear. Knockout Rapid Rescue utilises pro-biotic microbes for fast-acting stain and odour control, it is nature's cleaning workforce and a green and safe way to clean. Rapid Rescue is intentionally fragrance-free to reinstate “fresh air” and does not temporarily mask unwanted odours with fragrance, unlike many products
