Trial #3
To retest experiment done on 6/3/2021 to evaluate the effectiveness of Kitchen Cleaner for the removal of DCC-17 from ceramic, plastic, and stainless steel substrates.
Two cleaning products were retested and then compared: SIMS daily kitchen cleaner and Lysol kitchen cleaner. The same three ceramic, three plastic, and three stainless steel coupons were obtained and weighed for both of the products being tested. Coupons were then soiled with DCC-17 and allowed to air dry for 24 hours. After 24 hours of aging, a dirty weight was recorded. Coupons were then loaded onto a Gardner-scrub Straight Line Wash unit set to 10 cycles per minute for 20 cycles. Three pumps of cleaner were applied to each of the respective coupons and four pumps of cleaner were applied to the scrubbing blocks. The cleaner was allowed to sit for 30 seconds. Following the 30 seconds of resting, the SLW unit was run to simulate scrub cleaning. Coupons were then removed from the machine and allowed to dry in air for 24 hours. After the drying period, coupons were weighed, and a final clean weight was recorded. Effectiveness of the cleaners was determined.
SIMS Kitchen Cleaner was most effective in removing DCC-17 from plastic substrates by an average of 97.18% while Lysol Kitchen Spray removed an average of 5.49% off of plastic substrates. Lysol Kitchen Spray Cleaner was most effect in the removal of DCC-17 on ceramic substrates by an average of 99.37%, while SIMS kitchen cleaner removed an average of 70.89% of DCC-17 off of ceramic substrates.
