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.
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.
