Trial #4
Determining the efficacy of Case Medical's Ink and Adhesive remover on autoclave tape adhesive residue
After input from the client, this experiment was altered to better fit the needs of the company. Coupons were cleaned prior to testing, and 3 of each substrate were used for this test; Anodized Aluminum, Glass, Plastic, and Stainless Steel. Autoclave tape was taped along the middle of each coupon, and then heated in the oven for 30 minutes at 250 degrees Fahrenheit. Following heating, the tape was removed from the coupons in such a way that as much adhesive was left behind on the coupon surface as possible. Pictures were then taken of the "soiled" coupons, and were visually evaluated using the standard cleanliness evaluation scale, with a value from 1 to 5 being assigned. 5 being the most dirty, and 1 being the most clean. 3 lab staff were used for evaluation values, labeled as A, B, and C. Next, the coupons were individually loaded onto the straight line washability unit. Using a microfiber cloth, the case medical product was sprayed 6 times on the surface of the coupon and twice on the microfiber towel, and then run for the standard 20 cycles. Finally, pictures of the coupons after cleaning were taken, and were rated on the same scale as they were prior.
