Hi,
I tested cleaning FormLabs white resin with mr. Proper (or Mr. Clean) detergent in ultrasonic cleaner (frequency 40KHz @ 100W, , 48 deg. Celsius) and the result is dreadful - even if some part of the resin is cleaned what remained is very sticky (like tart) and it needs the IP and brushing.
It’s possible that for some other resins Mr. Proper (Mr. Clean) detergent works but not for FormLabs ones.
