CARPET CLEANING. EXTRACTION METHOD <br /> <br />Spot clean, vacuum, operate the extraction equipment, and re-vacuum all carpet in the <br />specified area. All vacuuming, both before and after cleaning shall be repeated until <br />there is no longer evidence of dry soil or cleaner residue in the carpet pile as <br />determined by examining the filter bag. All stained areas shall be. treated with spot <br />cleaning solution, following the directions of the manufacturer. Spot cleaning shall be <br />continued until as much of the stain as possible has been removed. Areas, such as <br />comers, which are inaccessible to the equipment, shall be cleaned with manual scrubbing <br />devices. After cleaning and allowing sufficient drying time, vacuum the carpet <br />following a pattern which will give the carpet pile a uniform appearance. <br /> <br />HOT WATER EXTRACTION <br /> <br />Hot water extraction provides rapid soil emulsification since most of the cleaners used for <br />extraction are low foaming and non-corrosive. They penetrate into the carpeting and <br />loosen the soil for easy removal while extracting. The pH of the detergent used should <br />never exceed 10.5. <br /> <br />A. Extractor Soecifications: <br />Use a self-contained hot water extractor with a minimum' of 100 psi water <br />pressure through the injection nozzles, a reel-type soft bristled agitation brush and <br />a water lift of 130 inches. <br /> <br />B. Equipment performance characteristics are critical to ensure effective and <br />complete extraction. <br /> <br />CARPET CLEANING CHEI\UCALS <br /> <br />Only pre-approved carpet cleaning chemicals will be used. Be sure that the chemical <br />manufacturer's recommendations and safety procedures are followed. Do not exceed the <br />recommended dilution ratios for any cleaning product. Chemicals used should conform <br />to all regulatory guidelines. <br />
