To evaluate aqueous cleaners on supplied parts using ultrasonic cleaning
Date Run:
12/08/2004
Experiment Procedure:
The three top products from the previous aqueous cleaning trial were used at the same dilutions (2%). Each beaker was immersed into a Crest 40 kHz ultrasonic tank filled with water heated to 115 F. The products were degassed for 5 minutes.
Parts were received contaminated with Fuch's Lubricants Renocut 6515 NC (mineral oil, vegetable oil) from the client. Two parts were cleaned in each product for 2 minutes with ultrasonics. Coupons were again rinsed in water at 120 F for 15 seconds and dried with air blow off at room temperature for 30 seconds. Once dry, final observations were recorded.
Trial Results:
Observation of the parts prior to cleaning revealed that each part was sufficiently coated with the Fuch's Renocut 6515 NC almost to the point of over coated. After cleaning no visible signs of oil were observable. The parts looked as clean as the parts previously cleaned with the client's current contact cleaner.
