Trial Purpose:
To test the efficacy of the client's glass cleaning product against comparative glass cleaning market products.
Date Run:
10/07/2024Experiment Procedure:
Three coupons for each substrate for each cleaner were weighed for initial weights. About 0.15-0.2 g of Glass soil that was made previously was put onto the coupons and was left to dry overnight (24-hour dry time). The following day, dirty weights were taken and recorded. Three coupons of the same substrate were placed in the SLW Machine; there were w per Wypall (one Wypall per substrate, per cleaner) amounting to about 2.5 ml of each cleaning chemistry per coupon. The SLW Machine was run for 20 cycles (30 seconds of cleaning). The coupons were taken out and left to dry for another 24 hours. After the 24 hours, they were weighed again for final weights.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Both the Seventh Generation Glass Cleaner and the Invisible Glass showed high efficacy across all substrates. The Windex was highly successful in removing the glass soil from mirror and glass, but struggled significantly in removing the glass soil from chrome. While the Green Mountain Amenities Glass cleaner showed to be effective in removing the glass soil from mirror and glass, it did not match the performance of the other three cleaners in removing the soil from mirror. It was able to match the performance of the other three cleaners in removing the soil from glass. The Green Mountain Amenities Glass Cleaner also struggled to remove the glass soil from chrome as the Windex did, however it was able to perform better than the Windex in this scenario.
