Trial #1
To evaluate aqueous cleaners for wax removal using ultrasonic cleaning.
There are no related objects.
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.
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.

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.
