ATTACHMENT E <br />EXTRA CLEANING PERFORMANCE STANDARDS <br />I. CARPENT CLEANING, EXTRACTION METHOD <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 there is <br />no longer evidence of dry soil or cleaner residue in the carpet pile as determined by <br />examining the filter bag. All stained areas shall be treated with spot cleaning, following <br />directions of the manufacturer. Spot cleaning shall be continued until as much of the stain as <br />possible has been removed. Areas, such as corners, which are inaccessible to the equipment, <br />shall be clean with manual scrubbing devises. After cleaning and allowing sufficient drying <br />time, vacuum the carpet following a pattern which will give the carpet pile a uniform <br />appearance. <br />A. HOT WATER EXTRACTION <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 shall <br />never exceed 10.5. <br />1. Extractor Specifications: <br />Use a self-contained hot water extractor with a minimum of one hundred (100) psi <br />water pressure through the injection nozzles, a reel -type soft bristled agitation brush <br />and a water lift of one hundred thirty (130) inches. <br />2. Equipment performance characteristics are critical to ensure effective and complete <br />extraction. <br />B. CARPET CLEANING CHEMICALS <br />Only approved carpet -cleaning chemicals will be used. Be sure that the chemical <br />manufacturers' recommendations and safety procedures are followed. Do not exceed the <br />recommended dilution ratios for any cleaning product. Chemicals used should conform to <br />all regulatory guidelines. <br />1. Spray Spotter (pH 8.5 to 9.5) <br />Spray the area to be cleaned. Allow the spray eight (8) to ten (10) minutes dwell <br />time. Extract the sprayed area with hot water only. Note: Do not spray too large an <br />area. If the spray is allowed to dry prior to extraction, it will not be effective. <br />2. Detergent (pH not to exceed 10.5) <br />Dilute the detergent to half (1/2) the chemical manufacturers specified ratio per <br />gallon of hot water, extract the carpet. If there are any large stains, it is advisable to <br />spray them with the spray prior to extracting. <br />II. NON-SPECIFIC TASK <br />Perform miscellaneous activities as directed by the property manager. The hourly price shall <br />include the price of any tool, item of equipment, chemical or supply if such type of item is <br />used in performing routine services as defined in the Specification. Should any tool, item of <br />equipment, chemical or supply not normally used in performing routine services be required <br />as directed by the City, such term shall be deemed to be not included in this Bid price and <br />shall be reimbursed to the Contractor. <br />III. STRIP AND REFINISH FLOORS <br />All unfixed furnishing such as tables, chairs, desks, trash receptacles, storage containers shall <br />be removed prior to stripping unless exempted by the City. A single disc floor machine, <br />stripping pad, putty knife, abrasive pad, mop, mop bucket and ringer, floor finish remover and <br />
