To evaluate four supplied products for all purpose cleaning following GS 37 requirements
Date Run:
09/23/2013
Experiment Procedure:
Preweighed Ceramic, Plastic, painted steel coupons were coated with Hucker Soil using a handheld swab and allowed to dry for 24 hours at room temperature. The contaminated coupons were weighed again to determine the amount of soil added.
Three coupons were placed into a Gardner Straight Line Washability unit. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with 2-3 sprays of cleaning solutions. Each coupon was sprayed 1-2 times with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded, efficiencies were calculated and recorded.
Trial Results:
All four products were effective at removing the DCC-17 from the three surfaces using manual wiping. The Green works resulted in the lowest efficiency, removing just over 87% of the Hucker Soil on ceramic coupon. The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for each coupon cleaned.
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Conclusion:
All of the four products were found to remove more than 85% of the Hucker Soil from various surfaces using manual wiping. The supplied product worked as well as the conventional cleaner and the on-the-market green cleaning product.
