To evaluate three supplied products for glass cleaning following GS 37 requirements
Date Run:
07/11/2008
Experiment Procedure:
Two of the three supplied cleaning product were diluted to vendor recommended concentration using DI water (32:1 and 128:1). In addition, the third product was prepared following the specified procedure - oxygenating cold tap water for about 10 minutes.
Preweighed chrome, glass and composite tile coupons were coated with SSL Soil 2 (Glass soap scum: Colgate Regular shaving cream 5.3%, Arid Extra Extra Spray Deodorant 3.5%, Suave Naturals Flexible Hold hair spray 3.7%, Aleeda Texurizing hair gel 25.6% Colgate Total toothpaste 10.4%, Water 51.5%) by pump spraying the mix. The soil was 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 Kimberly-Clark Wypal reinforced paper towel 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. The cleaning unit was run for 5 cycles (~9 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded, efficiencies were calculated and recorded.
Trial Results:
All three products were effective at removing the glass soap scum from the three surfaces using manual wiping. The Lotus Sanitizing System resulted in the highest efficiency, removing more than 90% of the soap film. The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for each coupon cleaned.
