Prochem Fourguard® Carpet Protector

This advanced chemical formulation is designed to deliver superior protection against water-based and oil-based soils and to reduce the damage caused by abrasion from dry soils on carpet and upholstery. Wear, age, pet damage, and improper cleaning can damage factory-added added acid dye blockers, but Fourguard replenishes these blockers to provide long-lasting stain protection from soft drinks, sports drinks, ink, coffee, tea, wine, urine, and more.
