Trial Number 2

Supplied products were diluted with room temperature water to the requested dilution. Preweighed glass, chrome 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 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 2-3 sprays of cleaning solutions.  Each coupon was sprayed 1-2 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. 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)

All three products removed over 92% of the glass soap scum using manual cleaning.One product had filming and spotting levels below the acceptable level from Green Seal.The other two products had better results than the conventional product for filming and streaking. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Visual Observations

The three products had an overall average removal efficiency greater than 85%. Filming and streaking observations for the supplied product were comparable to the conventional non-green product and the on-the-market green product.
