Supplied products were diluted used at the recommended/provided concentration for glass cleaning. Preweighed glass, 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 unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with 5-7 sprays of cleaning solutions. Each coupon was sprayed 7-10 times with the same cleaning solution. Then 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
dried with 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
7 = high filming 7 = high streaking poor (performance)
1 = no visible filming 1 = no visible streaking (excellent performance)
Chemistries Evaluated: PUREti Clean & Fresh; Conventional Glass Cleaner
Soil removal for the provided product and comparison product had very similar results. Both products removed more than 85% of the soil from glass and mirrored surfaces. The conventional product had a slight edge in removal 93 to 89%. When using a visual comparison, the filming assessment resulted in the PUREti having an average of 3.0 and the conventional product coming in at 2.7. Streaking/spotting were very close, with PUREti at 2.3 and the conventional product 2.0. The tables below list the cleaning results for removal, filming and streaking.
