To evaluate ozone generator system for all purpose cleaning
Date Run:
10/25/2013
Experiment Procedure:
Water and ozone generated water were used at full concentration (100%). Coupons were coated with wax three times for test. Before the cleaning, prepared VCT coupons were weighed. After then, the VCT coupons were soiled with Hucker's Soil Formulation (Jif Creamy Peanut Butter 9.2%, Salted Butter 9.2%, Arrowhead Mills stone ground wheat flour 9.2%, Egg Yolk 9.2%, Evaporated milk 13.8%, Distilled water 45.8%, Printer's ink with boiled linseed oil 0.9%, Shaws saline solution 2.7%) using a hand held swab and allowed to dry for 24 hours at room temperature. The contaminated coupons were weighed again to determine the amount of soil added. Each VCT coupon was placed into a Gardner Straight Line Washability unit. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with 5 sprays of cleaning solutions;10 ml of same cleaning solution were poured on each coupon. The cleaning unit was run for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a widow squeeze to remove residual cleaning solution. Final weights and gloss were recorded, efficiencies were calculated and recorded.
