Trial Purpose:
To test the effectiveness of The Pink Stuff on ceramic, stainless steel, and plastic.
Date Run:
09/02/2021Experiment Procedure:
Eighteen pre-weighed coupons, three of each substrate per cleaner, were soiled with 0.5 grams of DCC 17 (33% lard; 33% shortening; 33% vegetable oil and 1% carbon black powder) using a hand-held swab. Dirty weights were recorded after the coupons had dried for 24 hours at room temperature (68° F). Three coupons of the same substrate were aligned into a Single Line Washing Unit (SLW) with Wypall X60 attached to the cleaning sled. The Wypall X60 reinforced wipe along with the coupons were all sprayed two times with water after a small amount of the cleaner was added to each coupon; then the coupons were allowed to soak for 30 seconds. Afterward, the SLW was activated, and the coupons were cleaned for 20 cycles following an additional 20 cycles where a new Wypall was placed on the sled and sprayed again twice with water. Cleaned coupons dried overnight at room temperature before the final weights were recorded.
Trial Results:
Both cleaners were effective for the removal of glass soil from all three substrates. The Pink Stuff was 96% effective for ceramic and 97% effective for stainless steel and plastic. Soft Scrub was 92% effective for ceramic, 93% effective for stainless steel, and 98% effective for plastic.

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 cleaners were effective for the removal of kitchen soil from all three substrates.
