Trial Purpose:
To evaluate aqueous cleaners for potential replacement of contact cleaner.
Date Run:
11/08/2004Experiment Procedure:
Five products were selected from the lab's database of test results based on the products' past success in removing similar lubricants. Four of the products were diluted to 2% along with the client's current product using DI water in 600 ml beakers. A sixth product was used at full strength as recommended by the manufacturer. All six products were heated to 115 on a hot plate.
Eighteen preweighed 6061 aluminum coupons were coated with Fuch's Lubricants Renocut 6515 NC (mineral oil, vegetable oil) using a hand held swab. Coupons were allowed to sit for over an hour. A second set of weights were recorded to determine the amount of soil added. Three coupons were immersed into each cleaning product and cleaned using minimal agitation provided by a stir bar. Coupons were cleaned for 5 minutes, followed by a 15 second water rinse at 120 F and airblow off for 30 seconds at room temperature. Once dry, final weights were recorded and efficiencies were calculated for each product.
Trial Results:
All of the products out performed one of the client's current aqueous cleaners. Three of the products removed over 87% of the lubricant. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

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 same six products will be retested under similar conditions. Ultrasonic energy will be added to improve efficiency.
