Trial Purpose:
To evaluate successful cleaners using ultrasonic energy
Date Run:
11/27/2001Experiment Procedure:
The three cleaners were used at the same strength (20%) and temperature (140 F). Solutions were degassed in the Crest 40 kHz ultrasonic tank for 5 minutes prior to submersing parts. One part from the previous trial was cleaned in each of the solutions for 3 minutes. Parts were rinsed in a tap water spray for 1 minute at 120 F and dried with a heat gun at 500 F to decrease rusting. Observations were made after parts were dry.
Contaminant: White powders (SiO2, NHCl, (NH4)2SiF6, or NH4HF2)
Trial Results:
The additional 3 minutes of ultrasonic energy was enough to remove nearly all of the white powders from the steel parts. The Amberclean 527 L was the most successful cleaner used. The other two products were equally to each other in their cleaning results.

| Cleaner | Observations |
| Shopmaster | Good/excellent cleaning |
| Amberclean | Excellent Cleaning |
| Beyond 2001 | Good/excellent cleaning |
Success Rating:
A follow up test, usually based on company input.Conclusion:
A longer ultrasonic cleaning time would improve the results of removing the different white powders from the parts. Little of the green paint was removed during the immersion and ultrasonic cleaning.
