Safely removing tough spots and stains from colorfast carpet, rugs, upholstery and clothing. Folex is a water based non-ionic surfactant. It uses water to wash the stain away for virtually residue-free cleaning. Folex has a neutral charge so it will not attract or repel dust and dirt – the cleaned area will soil uniformly with the surrounding area. An emulsifying agent reduces surface tension, breaks up the stain and surrounds it. 32oz.
