Stain Remover. Proteins in urine work like glue, bonding the yellow pigment to carpet fibers. The Spot Gobbler Stain Remover formula contains advanced surfactants plus powerful enzymes that liquefy and digest these proteins. In turn, the stain is released from the fiber and can easily be cleaned away. Many of our customers swear it's the best they've ever used on urine stains. The Spot Gobbler's formula also works great on stains from coffee, fruit juice, baby formula, tea, food and more. Spot Gobbler Stain Remover is safe for any water-safe surface including carpets, upholstery and home laundry.
