OXY PRO is an advanced multi-surface cleaner that uses the power of hydrogen peroxide to lift away tough stains and soils from virtually any surface. It is specially formulated with a stable form of hydrogen peroxide at a high pH level so it remains in an active state for a longer period of time than other "oxygen-based" cleaners. On carpet it dries tack-free and the remaining residues are easily vacuumed away without leaving a noticeable difference in feel and appearance. Directions: Just spray on spot or stain and let dry on material then vacuum away. On other surfaces just spray and wipe away stain. USDA Authorized .
