Seven products were selected from previous trial based on effectiveness. Three products were diluted to 10% using DI water and four were used at full strength in 600 ml beakers. Each solution was heated to 130 F in a Crest 40 kHz ultrasonic tanked filled with water. The solutions were degassed for 5 minutes.

Twenty-one preweighed coupons were coated with Jackonslea Grey Color 305 A (1344-28-1) by heating the buffing compound to facilitate transfer to the stainless-steel coupons. Once cooled, coupons were weighed again to determine the amount of buffing compound applied. Three coupons were cleaned in each solution for 1 minute using 40 kHz ultrasonic cleaning. Coupons were rinsed for 15 seconds in 120 F tap water and dried using compressed air at room temperature for 30 seconds. Coupons were weighed a third time to determine the amount of soil remaining and efficiencies were calculated for each coupon cleaned.

Five of the seven products removed over 90% of the buffing compound in one minute of ultrasonic cleaning. The SC Supersolve and Soy Gold 2000 removed under 75%. The table lists the amount of buffing compound applied, the amount remaining after cleaning and the efficiency for each coupon cleaned.
