To evaluate cleaners on water-based buffing compound using immersion cleaning.
Date Run:
08/22/2006
Experiment Procedure:
The top two products from the previous trial were diluted to 5% in 250 ml beakers using DI water and heated to 130 F.
Six preweighed coupons were coated with the water-based compound using a handheld swab after heating. Coupons were weighed a second time to determine the amount of buffing compound added. Three coupons were cleaned in each solution for five minutes using immersion only. Coupons were rinsed for 15 seconds in a tap water bath at 120 F and dried using a dry compressed air for 30 seconds. Once dry coupons were weighed a final time and product efficiencies were calculated.
Trial Results:
The Polyspray 790 XS removed over 85% of the buffing compound using immersion cleaning. The Daraclean 283 removed about half. 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:
The addition of ultrasonic energy will result in an increase in efficiency for both products. Next steps will be to evaluate top cleaners on supplied parts at or after workshop.
