Clark,

Years ago when I produced resin kits, I recommended that the parts be scrubbed using a toothbrush and Ajax or Comet. The powdered cleaners seem to do a great job of removing mold release and/or oils left from your hands. Just be careful around the small details but don't be afraid to scrub fairly aggressively. Many of the liquid soaps have ingredients in them to soften your skin - not good for models.
