To evaluate four supplied products for all purpose cleaning following GS 37 requirements
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.
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.
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.
