Agar Citrus Extra Carpet Pre-Spray is a fast-acting, biodegradable, pre-spray detergent designed for use on all types of carpet. Agar Citrus Extra is diluted and then sprayed directly onto the carpet. It is then extracted with clean water. 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. Being a low-alkaline pre-spray, it is safe to use on carpets in trains, boats and planes and will not affect aluminium, fibreglass or painted surfaces. It is also less likely to cause skin irritations.
