Clothing stains are common, but you don't always know what they are or how they got there. That's why OxiClean® Max Force® Laundry Stain Remover is designed to include four types of stain-fighters to tackle more dried-in stains than other sprays: * Amylase Enzyme - lifts food stains from fabric * Solvents/Surfactants - dissolve and trap grease and oil * Polymers - bind to dirt and soils to suspend and rinse them away * Protease Enzyme - targets protein stains like grass and blood
