The purpose of this test is to check whether the supplied cleaners are effective in removing SSL Soil 2 (Glass soap scum) from the surface of the Glass, Chrome and Mirror coupons.
Date Run:
04/08/2014
Experiment Procedure:
Supplied products were used in full concentration (RTU Product). Pre-weighed Glass, Chrome, and Mirror coupons were coated with SSL Soil 2 (Glass soap scum: Water 51.5%, Hair gel 25.6%, Toothpaste 10.4%, Shaving cream 5.3%, Hair spray 3.7% and Spray deodorant 3.5%) using a handheld swab and allowed to dry for 24 hours at room temperature. The SSL Soil2 was soiled in the surface of the coupons. Coupons were left for 3-4 hours to dry. The contaminated coupons were weighed again to determine the amount of soil added.
Three coupons were placed in a Gardner Straight Line Washability unit. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with 4-6 sprays of cleaning solutions. Each coupon was sprayed 1-2 times with the same cleaning solution. The cleaning unit was run for 5 cycles (~10seconds). At the end of the cleaning, bottom part of the coupons was wiped once with a dry paper towel. After cleaning, cleaned coupons were left for 5 -6 hours to dry; possible residual cleaners on coupons from cleaning process were controlled. Final weights were recorded, efficiencies were calculated and recorded.
Visual observations were made on the coupons for spotting and filming following the general guidelines set forth in the CSPA DCC 09A. Filming is best recognized as "haziness" or overall "milkiness", while streaking is best identified as dried droplets or "spotting", usually found strung together into thin white lines. Each coupon was evaluated separately for filming and streaking, (i.e., product residues without added soil), according to a scale of "1" to "7" where:
Filming Streaking
7 = high filming 7 = high streaking poor (performance) 1 = no visible filming 1 = no visible streaking (excellent performance)
Trial Results:
All four supplied products removed over 85% of the glass soap scum using manual cleaning. Both Replenish glass cleaner reached overall 90% removal efficacy; both products were more effective on mirror and chrome than glass surface. In visual analysis, the filming and spotting levels on glass surface from the Replenish Glass TN-1300-87Dct was below the acceptable level from Green Seal. But the overall visual analysis passed the Green Seal standard. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for soil used.
