Trial Number 4

Client Number 286

Project Number 2

Trial Purpose:

To evaluate products on ink removal from galvanized steel using manual wiping.

Date Run:

01/15/2009

Experiment Procedure:

Seven products that were previously tested for client were based on performance. Each product was used at full strength and room temperature. Twenty-one preweighed galvanized steel coupons were coated with the supplied blue ink and allowed to dry. A second weighing was performed to determine the amount of ink added. Three coupons were placed into a Gardner Straight Line Washability unit. A 2-3 mL was applied to the coupons using a squeeze bulb. A Kimberly Clark Wypall X60 reinforced wiper was placed into the cleaning sled and also soaked with the cleaning solution. The machine was run for 30 seconds (~20 cycles), blotted dry with a fresh towel and weighed a final time to determine the effectiveness after 30 seconds. A second 30 second cleaning process was performed on the coupons to determine effectives after one minute of cleaning.

Trial Results:

Cleaning after 30 seconds had limited to moderate success for the seven products tested.

The additional 30 seconds improved efficiencies by 5-30% for the various products. The overall efficiencies were calculated for the full one minute of cleaning. The final removal rates were based on the data in the next table.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

The effective products will be evaluated on the supplied galvanized steel wire housing with ink markings.
