Trial Purpose:
To compare current cleaning alternative with other products.
Date Run:
09/12/2006Experiment Procedure:
Four alternative products were selected from the lab's database of testing results based on supplied client information. Products were selected based on buffing compound removal potential and compatibility with brass metal substrates. Each product was diluted to 5% in 250 ml beakers using DI water and heated to 150 F in a Branson 3510 ultrasonic tank. The client's current cleaning product also was diluted to 5% and heated to 150F.
Fifteen preweighed coupons were coated with the brown buffing compound using a handheld swab. Coupons were weighed a second time to determine the amount of buffing compound added. Three coupons were cleaned in each solution for one minute using 40 kHz ultrasonic energy. Coupons were rinsed for 15 seconds in a tap water bath at 120 F and dried using heated air (300F) for 60 seconds. Once dry coupons were weighed a final time and product efficiencies were calculated.
Trial Results:
All four alternatives removed more than the current cleaning product being used to remove the brown buffing compound with ultrasonic energy. Three of the four removed over 98% of the compound. The following table lists the amount of buffing compound applied, the amount remaining and the efficiency for each coupon cleaned.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
With several of the products successful for the removal of the buffing compound, the next step will be to evaluate these cleaners on supplied parts at or after workshop.
