<br />JANITORIAL MAINTENANCE SERVICES | Bid No. 19-08-02 29 <br /> <br />Prior to being damp mopped, the floor surface shall be dust mopped. When damp mopping, <br />a wet mop, mop bucket and wringer, and a neutral detergent solution, or cleaner degreaser <br />shall be used to remove all soil and non-permanent stains from the entire area. Mop bucket <br />solution shall be changed frequently so that solution remains clear. All accessible areas <br />shall be damp mopped. Chairs, trash receptacles, etc. shall be moved when necessary to <br />mop underneath. Mop is to be wrung well before damp mopping floors so that there is no <br />water standing on the floor during mopping process. After being wet mopped, floors shall <br />have a uniform appearance with no streaks, swirl marks, detergent residue, or any <br />evidence of soil. There should be no splash marks or mop streaks on furniture, walls, <br />baseboards, etc., or mop strands remaining in the area. All mops are to be changed every <br />two weeks to keep floors and grout clean. <br /> <br />D. Burnishing Finished Surfaces <br /> <br />When burnishing finished resilient tile, sealed concrete, terrazzo, quarry tile, or other <br />finished floor surfaces, prepare the surface by removing any wet spills with a damp mop. <br />Dried residue (gum, etc.) should be removed with a putty knife and/or Freon. Dust mop <br />the entire surface to be burnished with a lightly treated dust mop or a treated disposable <br />pad. Using a 17 inch to 32 inch high speed burnisher (1500 to 2500 RPM) equipped with <br />a gold or yellow burnishing pad, begin by following a straight line to the extent of the <br />machine or the confines of the area. Turn the machine 180 degrees and parallel the original <br />path overlapping up to 4 inches. Continue this procedure until the entire area has been <br />burnished. Check pads frequently for buildup and reverse or replace as needed. <br /> <br />When burnishing has been completed, dust mop the floor area again to pick up any loose <br />soil or dust which may have been dislodged during burnishing. Wipe the base and any low <br />wall areas to remove dust accumulation that may have resulted from the burnishing. When <br />the burnishing has been completed, the floor surface shall have a uniform high gloss with <br />no swirl marks or blemishes. The solution will be applied thinly, uniformly and evenly in <br />such a manner as to avoid skipping of areas. Walls, baseboards, furniture and other <br />surfaces will be free of solution residue and marks from the equipment. <br /> <br />Clean equipment before storing. Damp wipe the machine paying particular attention to the <br />cord. Wash all pads in warm water until clean and hang on peg until dry. Vacuum the dust <br />mop head to remove any dust, dirt, or debris and hang on a suitable tool holder. <br /> <br />E. Wet Mop-Scrub Floors <br /> <br />Prior to being wet cleaned, the entire floor surface involved shall be dust mopped, except <br />in small restrooms where dust mopping is obviously not required. A wet mop, mop bucket <br />and wringer, scrub brush, floor squeegee and neutral detergent or germicidal disinfectant <br />shall be used to remove all soil and non-permanent stains from the entire floor, <br />baseboards, etc. When necessary, a cleaner degreaser must be used. The cleaning solution <br />shall be applied to the entire floor area and allowed to remain for three to five minutes. <br />Then the entire floor area shall be scrubbed with a scrub brush. In areas with floor drains, <br />the floors shall then be squeegeed dry and then rinsed with clear water. In areas without
