Trial Purpose:
To evaluate top six products on third supplied contaminant using immersion cleaning.
Date Run:
10/09/2008Experiment Procedure:
The top six products based on past testing results were again diluted to 5% using DI water in 400 ml beakers. All six products were heated to 130 F on a hot plate. Peweighed aluminum coupons were coated with the Hagsterfer's Crystal Brite EDM oil using a handheld swab. The contaminant was allowed to dry for about 10 minutes. Once dry, the coupons were weighed a second time to determine the amount of oil applied.
Three coupons were immersed into each solution and cleaned for 5 minutes using stir-bar agitation. Rinsing was performed for 15 seconds using tap water heated to 120 F and followed by 30 seconds of air blow off with dry compressed air at room temperature. Final weights were recorded, and efficiencies were calculated for each coupon cleaned.
Trial Results:
All six products were effective at removing the EDM oil from the aluminum coupons within 5 minutes of immersion cleaning. Five of the six removed over 99% of the EDM fluid. The sixth removed over 97%. 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 top products will be evaluated on the fourth supplied contaminant under the same cleaning conditions.
