Date Run:
05/29/2014
Experiment Procedure:
Three coupons were placed in a Gardner Straight Line Washability unit. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with 4-6 sprays of cleaning solutions. Each coupon was sprayed 3-5 times with the same cleaning solution. The cleaning unit was run for 20 cycles (~33seconds). At the end of the cleaning, bottom parts of the coupons were wiped once with a dry paper towel. Final weights were recorded, efficiencies were calculated and recorded.
