Fizzion’s 2-tablet refill makes up to 23 oz. (per tablet) of their award-winning Pet Stain and Odor remover (bottle not included). This is the most powerful cleaning solution on the market to spot-treat pet messes on carpets, fabrics and most hard surfaces in your home or business. Unlike enzymatic cleaners that require long waiting periods to activate, Fizzion works instantly. Fizzion's non-toxic, environmentally friendly solution quickly goes to the root of the stain and odor, forming a shield around the stain, immediately reducing odors. There is no waiting time - just spray, wipe and watch your stain disappear permanently. Fizzion is comprised of a proprietary blend of cleaners to create an unmatched detergency that removes the two most stubborn components of urine from most materials or fabrics. To prevent the odor from returning, Fizzion's powerful CO2 action takes normally insoluble uric acid in urine and makes it soluble, so that it can be removed from the surface.
