Trial Number 1
Trial Purpose:
The purpose of this experiment was to repeat previous testing on ceramic substrates.
Date Run:
10/14/2020
Experiment Procedure:
Three ceramic coupons were obtained and weighed for each of the two cleaners being tested. Coupons were then soiled with Hucker's Soil, and the soil was allowed to dry for 2 hours. A dirty weight was obtained after the 2 hours had passed. Coupons were then placed into the Straight Line Wash (SLW) unit. The cleaner block and each coupon were sprayed with two pumps of their respective cleaners, 409 All Purpose Cleaner and Skrubbr both ready-to-use. The SLW unit was then run for 20 cycles to mimic 30 seconds of manual wiping. Coupons were then dried in air for 24 hours and a clean weight was obtained. Effectiveness of the cleaners was then determined.
