Few of us have been using a water based technique. I scrape the part into a lightly heated ultrasonic cleaner with Yellow Magic. On fragile parts or parts that are thin and susceptible to warping I will post cure in the solution with a uv lamp to remove the tacky. Unfortunately my UV lamp is not all that great so it takes a while. Beefier less critical parts I rinse the YM off the part dry it with a small compressor then give it a quick scrub in IPA then dry immediately.
JD first researched and found YM as one of the solutions to try and it really well. Prior to that my retired Uncle who was a chemist had modified a detergent base solution for this purpose but it is too costly to bring to market and YM actually works better because it is reclaimable.
