CITRUS EXTRA is based on natural orange oils which have a strong cleaning action and a pleasant fragrance. CITRUS EXTRA¢s excellent cleaning power provides great economy of use and does away with the need for detergent or additives in the solution tank or the feed lines of truck-mounted units. CITRUS EXTRA is a free rinsing cleaner, so after pre-spraying, one pass with water in the wand is all it takes to clean and revive the carpet. A fast-acting, biodegradable, pre-spray detergent, CITRUS EXTRA is designed for use on all types of carpet. CITRUS EXTRA is diluted and then sprayed directly onto the carpet. It is then extracted with clean water.
