Trial Purpose:

To evaluate performance of possible aqueous based cleaning products for various oil removal.

Date Run:

10/09/2008

Experiment Procedure:

Eight products were selected from the lab's on-line database, www.cleanersolutions.org, based on past testing results matching client supplied information. A ninth product was requested by the client. All of these products were diluted to 5% using DI water in 400 ml beakers. All nine products were heated to 130 F on a hot plate.

Peweighed aluminum coupons were coated with the Houghton Houghto Draw 7007 (64742-52-5) metal working fluid using a handheld swab. The contaminant was allowed to dry for about an hour. 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 nine products removed over 97% of the drawing fluid from the aluminum coupons within five minutes of immersion cleaning. Seven of the products removed more than 99%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
