Trial Purpose:
To evaluate three supplied cleaning products for Hucker’s soil removal from various surfaces.
Date Run:
10/17/2016Experiment Procedure:
Three cleaners (Catholyte NaOH, Anolyte Hypochlorous, and 409 All Purpose Cleaner) were received “Ready to Use” (RTU). Pre-weighed coupons (three ceramic, three painted steel, three stainless steel, three plastic) were coated with one gram of Hucker’s soil, at room temperature, using a hand held swab. The contaminated coupons were air dried for 2 hours at room temperature and weighed again to determine the amount of soil added.
Three coupons of each substrate were placed in the SLW unit and a KC Wypal reinforced paper towel was attached to the cleaning sled and treated with two sprays of cleaning solution. Each coupon was sprayed twice with the same cleaning solution. The cleaning unit was run for 20 cycles (equivalent of 30 seconds of cleaning). Coupons were dried and final weights were recorded. Efficiencies were calculated and recorded.
Trial Results:
The three supplied products on average removed over 93% of the Hucker’s soil on each substrate using the manual wipe unit.
