Trial Purpose:
To evaluate aqueous cleaners for wax removal using ultrasonic cleaning.
Date Run:
09/17/2009Experiment Procedure:
The same ten products were used again at the same temperature and concentrations. Products were degassed for 5 minutes prior to cleaning. The coupons that were used in the immersion cleaning were reused for the ultrasonic testing. (Therefore, coupons were soaked for 5 minutes and then cleaned with ultrasonics for another 5 minutes). Cleaning was followed with a tap water rinse at 120 F for 15 seconds and dried using compressed air at room temperature for 30 seconds. Final weights were measured and efficiencies calculated.
Trial Results:
Several of the aqueous products were effective at removing the wax from the glass coupons using ultrasonic energy. Two products (one being the supplied product) removed more than 98% of the wax in less than the five minutes. The table lists the amount of wax left after the initial 5-minute soak, the amount remaining after the 5 minutes of ultrasonic cleaning and the efficiencies for each coupon cleaned.

Success Rating:
A follow up test, usually based on company input.Conclusion:
The top performing products will be tested at higher temperatures in addition to ultrasonic cleaning. Concentration may be another variable to modify to improve efficiency.
