Trial Purpose:

To evaluate past effective products on second set of supplied parts contaminated with cutting and lubricants.

Date Run:

06/26/2008

Experiment Procedure:

The top five products were selected from the previous lab trial. Products were diluted to 5% using DI water in 300 ml glass beakers. Water also was used. Solutions were heated to 130 F. The beakers, were immersed in a water bath in a Branson 40 kHz ultrasonic tank. Products were degassed for five minutes.

A set of three soiled steel parts (coated with cutting fluids and lubricants) were immersed into each product and cleaned for 5 minutes using ultrasonic agitation. Following cleaning, coupons were observed for cleanliness.

Trial Results:

The Daraclean 282 GF cleaned parts at both 5 and 10% dilutions at 130 F were visually the cleanest. At 5%, Micro 90 was the next cleanest followed by Polyspray Jet 790 XS. At 10%, Polyspray Jet 790xs was the second most effective product followed by M Aero.
