To evaluate the effectiveness of the removal of glass soil from chrome, mirror, and glass using Honest cleaner.
Date Run:
11/10/2021
Experiment Procedure:
Three coupons of each substrate (chrome, glass, and mirror) were collected and initial weights were taken. Glass soil was applied to each coupon and allowed to air dry for 24 hours. After the 24 hour dry time, the weights of the newly contaminated coupons were measured. All coupons were placed into a Straight-Line Washability (SLW) machine. A KC Wypall cleaning cloth was attached to the cleaning block used for the test. The Wypall cloth and all coupons received 2 sprays of the Honest Cleaner and the SLW machine was run for 20 repetitions, simulating 20 manual wipes. Once cleaning concluded, the cleaned coupons were allowed to air dry for 24 hours. After 24 hours, the weights of the cleaned coupons were measured.
Trial Results:
Glass had the highest percentage removal with an effectiveness of 95%. Chrome had an average of 92% and mirror had an effectiveness of 85%. All coupons visually looked like the soil was completely removed from the substrate.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Conclusion:
Honest cleaner was effective for the removal of glass soil from all three substrates.
