Trial Number 1

Trial Purpose:

To evaluate supplied products for glass cleaning.

Date Run:


Experiment Procedure:

The supplied cleaning products were used at the recommended concentrations (2% and 1.5%).

Six preweighed chrome and three glass 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 hand held 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. 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 recorded and efficiencies recorded.

Trial Results:

Product #108 and Blue Jay worked well on the glass soap scum. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
