In general, we recommend use Ethanol (preferred) or IPA and a painter brush (or any brush made of hair) to remove uncured resins. Ultrasonic cleaner is not needed and sometimes not recommended.
We also recommend use 390-405nm UV light for post curing. For hard to cure resins like Blu and Tenacious, submerge in water will speed up curing. For Fast and Simple, submerge is not needed. Prints should be dried before post curing.
