Trial Purpose:
To evaluate supplied products for glass cleaning using manual cleaning
Date Run:
04/17/2015Experiment Procedure:
Supplied products were diluted with room temperature water to the requested dilution.
Preweighed 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 contaminated coupons were weighed again to determine the amount of soil added.
Three coupons were placed into a Gardner Straight Line Washability (SLW) unit. A Wypall L20 reinforced wipe was attached to the cleaning sled and soaked with 1 spray of cleaning solution. Each coupon was sprayed 1-3 times with the same cleaning solution. The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 5 cycles (~10 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were measured and efficiencies 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
1 = high filming 1 = high streaking (poor performance)
7 = no visible filming 7 = no visible streaking (excellent performance)

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Each of the cleaners exhibited the same level of soil removal for each surface, requiring a visual analysis to determine the optimal cleaner. Based on the filming and streaking table, we can see that Great Value was the highest performing mirror cleaner, followed by Windex and the WC formulations. For glass, Windex was the highest performing cleaner, followed by Great Value and the WC formulations.
