Trial Purpose:
To evaluate supplied product for glass soil removal from glass and chrome surfaces.
Date Run:
06/06/2017Experiment Procedure:
The following experimental procedure follows TURI’s cleaning standard for SCL 2 glass soap scum.
Soiling Process:
Pre-weighed chrome and glass coupons were soiled with SSL Soil 2 glass soap scum using a hand held swab. The glass soap scum is made from a blend of water 51.5%, hair gel 25.6%, Toothpaste 10.4%, shaving cream 5.3%, hair spray 3.7% and spray deodorant 3.5%. The coupons were allowed to dry for 24 hours at room temperature before re-weighing for the amount of contaminated added onto the coupons.
Cleaning Process:
Three of the same type of coupons were placed into a Gardner Straight Line Washability unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with 1 spray of cleaning solutions. Each coupon was sprayed once with the same cleaning solution. Each cleaning solutions were diluted to the suggested dilution provided by the vendor. The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 5 cycles (~10 seconds).
Efficacy Rating Process:
The coupons were left to sit at room temperature in time intervals of: 1 hour, 1 day after the cleaning process before re-weighing the coupons for the amount of contaminants removed. Three testers were used to do a visual ranking to measure the efficacy of the cleaning agents. The visual ranking of the cleaned substrates was in accordance to the following ratings:
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" meaning;
Filming Streaking
7 = high filming 7 = high streaking poor (performance)
1 = no visible filming 1 = no visible streaking (excellent performance)
Trial Results:
Comparative Analysis
All efficacy rating mentioned in the following comparative analysis is from the overnight sit drying time, because there was no significant increase in glass soap scum removal between the 1 hour drying time and from the overnight sit.
The sample cleaner: SWR One had a similar efficacy rating as the comparative cleaner: Suma Break-Up HD Degreaser when removing glass soap scum from glass coupon; with respective efficacy ratings of: 96.84% and 95.04%. Similarly, the filming on the glass coupons were observed to not be significantly greater than the comparative cleaner; with respective filming ratings of 4.0 in comparison to 3.7. However, the sampled was observed to be slightly more effective than the comparative cleaner in terms of the visual streaking rating; with respective streaking ratings of 4.6 as opposed to 5.5.
Furthermore, the sample cleaner was just as effective as the comparative cleaner in cleaning glass soap scum from chrome plated aluminum coupons; with respective efficacy ratings of 95.19% and 95.04%. Whereas, the sampled cleaner had a similar rating as the comparative cleaner; with respective film ratings of 2.6 and 2.9. Similarly, the visual streaking for the sampled cleaner was observed to be slightly better than the comparative cleaner; with respective streak ratings of 2.9 and 3.3.
