Trial Purpose:
To evaluate successful cleaners on the third supplied contaminant
Date Run:
07/12/2004Experiment Procedure:
Five cleaners were selected from the previous trial. All products were diluted to 5% using DI water in 600 ml beakers. All nine products were heated to 120 F on a hot plate. Fifteen preweighed aluminum coupons were coated with client supplied cutting fluid, WA Wood Co Maxoline 75 grinding oil (64741-97-5, 63449-39-8), using a hand held swab and then weighed a second time to determine the amount of soil added. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. Coupons were rinsed in tap water for 15 seconds at 120 F, followed by air blow off at room temperature. Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.
Trial Results:
All five products removed over 95% of the cutting fluid. The table below 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 next step will be to test supplied parts using the successful products in immersion and ultrasonic cleaning.
