Trial Purpose:
To evaluate successful products on supplied oil using manual wiping.
Date Run:
12/22/2008Experiment Procedure:
Ten products were selected from the previous two trials based on success on the supplied ink. All of the products were used at full strength at room temperature.
Peweighed steel coupons were coated with the US Oil Company US Penetrant (8052-41-3, 64742-52-5, 111-76-2) contaminant using a handheld swab. The contaminant was allowed to dry for at least a day and then were weighed a second time to determine the amount of oil applied.
Three coupons were placed into a Gardner Straight Line washability unit (designed for manual cleaning testing). The cleaning solutions were applied to the three coupons and allowed to sit for one minute. Simulated manual cleaning was run for 40 cycles or about one minute. Following cleaning, the coupons were dried 30 seconds using air blow off with dry compressed air at room temperature. Final weights were measured, and efficiencies were calculated for each coupon cleaned.
Trial Results:
Seven of the ten removed over 85% of the oil using manually wiping. Three of the seven resulted in greater than 90% removal. The table lists the initial weight of the oil, the final weight and the cleaning efficiency for each coupon cleaned.

Success Rating:
A follow up test, usually based on company input.Conclusion:
Even though a couple of products were not as successful as the others, all ten products will be evaluated on the supplied grease following the same cleaning process. This decision was based on the success of the products on the supplied ink.
