Fiber-Tec (previously known as Fiber-Tec 1:4) is a concentrated water-based carpet and upholstery protector formulated for ease of use. Fiber-Tec protects against both oil and water-based stains and repels dry soil, leaving a protected surface that resists reoccurring soils and stains. With no fluorocarbons or solvents, Fiber-Tec is safe to use in all indoor environments and can be applied without fear of damage to the carpet or upholstery one is working with.
