Trial Purpose:
An all-purpose test to evaluate the removal of huckers soil from ceramic, plastic, and painted metal using microfiber towels.
Date Run:
03/12/2021Experiment Procedure:
Three coupons for each substrate for each cleaner, a total of 18 coupons, were pre-weighed for initial weights. Hucker's soil that was made prior to testing was distributed over the middle of the coupon and was left to air dry for 2 hours. After 2 hours, the coupons were weighed for dirty weights. The microfiber towel that was provided was cut into 6 strips that would fit the SLW machine, 1 strip for each substrate per cleaner. 3 coupons of the same substrate for each cleaner was placed in the SLW machine, the microfiber towel was sprayed 3 times per substate, per cleaner, and was run for 20 cycles/wipes. The coupons were taken out and dried for an hour. After they were dry, the final weights were recorded.
Cleaners Evaluated:
- Pathosans
- Formula 409
Trial Results:
Both cleaners were effective for the removal of hucker soil using a microfiber towel for all substrates. Pathosans averaged 98% for both ceramic and plastic and 97% for painted metal. Visually the coupons had full removal. Formula 409 averaged 96% for ceramic, 2% less than Pathosans, and 97% for painted metal. The plastic substrate averaged 100.9, two of the 3 coupons were under 100, but one was above. This could be due to the coupon having leftover soil on the coupon prior to the initial weights. Visually all coupons were clean with minimal soil left.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
Both cleaners were effective for the removal of hucker's soil from all three substrates.
