A powerful extraction emulsifier that also neutralizes after cleaning and uses encapsulating polymer technology to help prevent resoiling! This is a cutting edge technology that allows you to get carpets cleaner and help them stay cleaner longer, a major benefit to your customers. Powerful surfactants emulsify tough soils including sand and other particulates that pre-sprays just can't remove. End Zone then neutralizes carpet to a slightly acid pH and its polymer technology helps prevent browning, wicking and resoiling. Fibers are left squeaky clean in a neutral or slightly acid state, perfect for the application of carpet protector, without a separate step!
