ForceField FireGuard Flame-Retardant Treatment - set of 4 sprays - 22oz each by iDecor [can be safely applied to clothing, fabrics, draperies, furniture, carpets, upholstery, textiles] BEST DEAL form iDecor - set of 4 ForceField FireGuard Sprays Revolutionary, water-based, flame-retardant treatment that can be easily and safely applied to clothing, draperies, furniture, carpets, rugs, and/or numerous other surface treatments. FireGuard should only be used on water-safe fabrics and surfaces. If uncertainty exists, always test for suitability by applying the product to a small inconspicuous area of the item and wiping with a white cloth. For best results, apply to clean, dry surfaces. FireGuard can be applied either by spraying or dipping. The key to FireGuards ability to retard flames is its organic ammonium salt formulation. When exposed to flames or intense heat, an acidic catalysis occurs resulting in the formation of an inert gas that blankets the surface. Because of this blanket, there is no oxygen available at the surface and flames cannot form.
