Trial Number 0

(Client Number 323, Project Number 1)

Trial Purpose: To evaluate supplied cleaning process with an traditional glass cleaning product.

Date Run: 09/21/09

Experiment Procedure:
All three products were used at the supplied concentration (100%) at room temperature.

Preweighed chrome and glass 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 Texturizing 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 microfiber cloth 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. Final weights were recorded and efficiencies were calculated and recorded. In addition, a panel of three staff members reviewed the cleaned coupons to determine the level of streaking and filming following CSPA DCC 09A. They ranked the two sets of cleaners based on which product had less streaking and filming.

Streaking and Filming Performance
Streaking is best identified as dried droplets or "spotting", usually found strung together into thin white line while filming is best recognized as "haziness" or overall "milkiness" Each mirror panel is evaluated separately for filming and streaking, (i.e., product residues without added soil), according to a scale of "1" to "7".

Streaking
7 = high streaking (poor performance)
1 = no visible streaking (excellent performance)

Filming
7 = high filming (poor performance)
1 = no visible filming (excellent performance)

Trial Results
The supplied cleaning process was effective in removing the glass soap scum from the three surface materials. Even though water was able to remove
over 85% of the soap scum, it left behind substantial amounts of filming on the surfaces. The first table lists the amount of soil added, the amount
remaining and the efficiency for each coupon cleaned. The second table lists the visual observations made by the testing staff for streaking and
smearing following the CSPA DCC09A methodology.
