Trial Number 1
Trial Purpose:
To evaluate the effectiveness of Sims Bathroom cleaner for the removal of bathroom soil from chrome, ceramic, and plastic substrates.
Date Run:
06/02/2021
Experiment Procedure:
Three coupons for each substrate were weighted for initial weights. Using the Janitorial Standard Bathroom-GS 37, the coupons were soiled on one side and were left to dry for 24 hours. After the coupons were dry, they were loaded in the Straight Line Washability Unit (SLW) three at a time by substrate. A Kimberly-Clark Wypall was attached to the cleaning sled and was sprayed twice with the cleaner. Each coupon was also sprayed three times before the SLW unit ran for 20 cycles. After the 20 cycles, the coupons were placed on a tray and were left out to dry overnight. The final weights were taken once dry.
Trial Results:
Both cleaners were successful for the removal of bathroom soil #1 from all three substrates. Sims Bathroom cleaner averaged 98% for chrome and 97% for ceramic. It also averaged 90% for plastic which was 5% over Clorox Bathroom which averaged an effectiveness of about 85%. Both chrome and ceramic averaged about 96% for Clorox Bathroom.
