Trial #8
To evaluate cleaners from previous grease trial using ultrasonic energy
Five cleaners from the previous trial were diluted to 10% in 250 ml beakers. A sixth product was used at full strength. All products were suspended in a Branson 3510 ultrasonic tank (40kHz) filled with water at 130 F and degassed for five minutes. Eighteen preweighed coupons were coated with Hibrenia Way Apiezon M1 grease using a hand held swab. Coupons were then reweighed. Three coupons were cleaned in each product for 5 minutes using ultrasonic energy. At the end of cleaning, coupons were rinsed with tap water at 120 F for 15 seconds and dried using air blow off for 30 seconds at 68 F. Once dry, coupons were weighed a final time and efficiencies were calculated.
All six products removed over 98% of the grease within the five minutes of ultrasonic cleaning. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon.
