To evaluate supplied cleaners on second soil mixture on chrome coupons.
Date Run:
02/20/2003
Experiment Procedure:
Four supplied cleaning products were diluted to vendor recommended concentrations for glass cleaning. Each product was diluted with DI water. Twelve preweighed chrome 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. Photographs were taken.
Three coupons were placed into a Gardner Straight Line Washability unit. A Professional Painter's Rag 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 and a second set of photographs were taken. Efficiencies were calculated and recorded.
Trial Results:
All four products were successful in removing SSL Soil 2 from chrome coupons. The table below lists the amount of soil added and removed. Table 1. Soil Application and Removal
