If I remember correcty,  it is also recommended that you do not handle the cleaned parts with your bare hands.  The  oil on your hand can mess up the paint job.

Good luck,

Good thing I don't have arthritis in my feet.

Sylvan Models recommend their own Resin-Prep cleaner, but also mention Diosol as an alternative - I used lacquer thinner (similar to Diosol) and while it worked well, it did distort some smaller parts.
Westerfield, as Dave has mentioned, recommends dish detergent, as does Funaro & Camerlengo, Wright-Trak, and Speedwitch.

Dish soap and water should work on any resin kit.  The Westerfield website says this: "The first and most important thing to do before painting is to take extra time in cleaning the kit resin castings.  You should use a good degreasing detergent (Dawn) and lots of rinsing with water to make sure that all of the mold release agents are removed.  Wash and carefully scrub the castings as needed, then allow to completely dry. "

Alcohol can have odd consequences (I seem to recall some guys who used it to strip paint on Kato business car models ended up making the plastic very brittle) and I would suggest sticking to dish soap, water, and if possible some scrubbing with an old toothbrush.

I have a bottle of Polly S Plastic Prep liquid but I have not tried it on resin kits since the dish soap works OK. It appears to have a solvent mixed with ethanol.

The kit instructions should include information for removing the mould release agents - this often varies from one manufacturer to the next, and what works for one might destroy another.

I have several resin model kits. Will soap and water or rubbing alcohol work to clean the parts prior to painting. Thank you
