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