Trial Number 1

Trial Purpose:

To evaluate selected cleaners using manual cleaning

Date Run:

05/04/2004

Experiment Procedure:

Seven products were selected based on results from the first trial. Each product was used at full strength. Twenty-one preweighed steel copper coupons were coated with the buffing material, Henkel Loctite Clover Silicone Carbide Grease Mix grit size (64742-52-5, 1592-21-2, 1333-86-4), using a hand held swab. Coupons were weighed a second time to determine the amount of soil added to each coupon. Three coupons were placed into a Gardner Straight Line Washability unit. A Professional Painter's Rag was soaked with a cleaning solution and then attached to the cleaning sled. The cleaning unit was run for 10 cycles (~15 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded and efficiencies were calculated and recorded.

Trial Results:

All seven products removed over 95% of the buffing compound mix in less than 15 seconds using manual wiping. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
