To evaluate client requested products on the first soil
Date Run:
07/08/2004
Experiment Procedure:
Three cleaners were requested from the client. Six aqueous based cleaners were diluted to 5% using DI water in 600 ml beakers. All three products were heated to 120 F on a hot plate.
Nine preweighed titanium coupons were coated with client supplied tapping fluid, Castrol Industries Moly Dee Tapping fluid (63449-39-8, 64741-96-4), 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:
Two of the three products removed over 85%. The third product removed just under the 85%. The table below lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
