Trial Purpose:

To test the effectiveness of Podsy in the removal of Hucker's Soil from various substrates.

Date Run:

09/08/2021

Experiment Procedure:

A Podsy solution was created by placing a solution pod into a spray bottle and filling it with cold water (~50^oF). This solution was allowed to sit for 2 minutes and then shaken to mix the solution parts together. Then, 3 coupons of each substrate (ceramic, plastic, painted metal) were collected and initial weights were taken. Hucker's Soil (Creamy Peanut Butter, Salted Butter, Wheat gluten, Egg Yolk, Evaporated milk, DI water, Printer's ink with boiled linseed oil, India Ink, Saline Solution) was applied to each coupon and allowed to air dry for 2 hours. After the 2 hour dry time, the weights of the newly contaminated coupons were measured. All coupons were placed into a Gardner-scrub Abrasion Tester machine. Wypall cleaning cloths were attached to each of the 3 cleaning blocks used for the test. Each Wypall cloth and all coupons received 2 sprays of the Podsy solution and the Gardner-scrub Abrasion Tester 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.

Podsy had an average effectiveness of 97% for ceramic, 95% for plastic and 97% for painted metal. Formula 409 had an average effectiveness of 94% for ceramic, 94% for plastic and 95% for painted metal. Posdy had a higher removal effectiveness for all three substrates.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

Podsy was more effective in the removal of Hucker's Soil from ceramic, plastic, and painted metal substrates than the comparison product Formula 409.
