Trial #3
To evaluate selected products for UV ink removal using heated ultrasonics with various dilutions of SC Supersolv
Sc Supersolv was diluted to a 75% concentration in an unheated ultrasonic bath at a common parts cleaning frequency of 40kHz. Each solution was degassed (removal of any excess bubbles to improve energy transmission) for 10 minutes. A saw blade was immersed into a solution and cleaned for 9-10 minutes. At the end of each cleaning cycle parts were observed for paint removal and wiped once with a wypall paper towel. Testing completed after a total 30 minutes.

The ink on both parts did not have any removal after each cleaning cycle or with the addition of a Wypall wipe step. Vigorous wiping after testing only removed some flakes. A heated immersion and ultrasonics can be explored next to see if the temperature could improve the removal.
Unheated ultrasonics using a 75% concentration of SC Supersolv was not effective.
