1) Put on gloves.
2) Full dip in 99% alcohol bath, with agitation (gentle shaking) for 5 minutes or so. Then I leave them sit in the alcohol for 5-10 minutes more.
3) Remove from bath, and dry thoroughly. Use compressed air to get alcohol out of cracks and such.
4) Remove any supports.
5) Fill any holes/defects with a small touch of liquid resin, and cure it instantly with a UV laser pointer.
6) When that's all done, carefully dip the model into a clear jar of water (you don't want bubbles around it) and expose it to intense UV light for 10 minutes. Oxygen keeps the resin from curing fully, so that's why the model needs to be underwater during the UV hardening.
If the resin is still tacky after 10 minutes, hit it again with the UV light. Keep going until it's not tacky.
This is my UV curing system. Cost me all of $20 to build from a paint can and a string of UV LEDs from Amazon. The LEDs are waterproof, so I can fill the can with water directly if I'm curing a larger print, but I prefer to use glass jars when I can.
7) Take off gloves.
