Trial #2
To evaluate the effectiveness of Sims Glass cleaner for the removal of glass soil from chrome and glass substrates.
Three coupons for each substrate were weighted for initial weights. Using the Janitorial Standard Glass-GS 37 and Glass - DCC, the coupons were soiled with glass soil #2 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.
Sims Glass cleaner averaged about 96% effectiveness for both chrome and glass, performing better than Windex. Windex averaged 87% for chrome and 95% for glass. Both cleaners were effective for the removal of glass soil on both substrates. Visually the coupons were all clean with minimal streaking after completely dry.
