Seven cleaners were selected from the previous trial. All were aqueous based and were diluted to 5% using DI water in 600 ml beakers. All seven products were heated to 120 F on a hot plate.
Twenty-one preweighed titanium coupons were coated with client supplied tapping fluid, Master Chemical Corp Trim C270 (102-71-6, 63231-48-1, 141-43-5), 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.
All seven products removed over 85% of the cutting fluid within five minutes. One product removed under 90%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
