I talked with someone at the Sylvan Scale booth at the Amhurst MA show a couple of years ago on the same subject. He recommended a citrus based cleaner at that time as well. I found a citrus cleaning product at Home Depot in a spray bottle. For the small amount of cleaner needed to clean a vehicle casting, this is probably a lifetime supply. It looks and smells just like the small bottle of Resin Prep I got at the show.

You are very close to the actual product by mentioning a citrus based cleaner. Clare Gilbert, the owner of Sylvan Scale Models, mentioned in a clinic that his Resin Prep is just a citrus based cleaner called Citrasolve. (check spelling) He buys it in 5 gallon pails and repackages it as Resin Prep.
I use the original Dawn without the lotion, or Soft-Scrub. Both with warm water and a tooth brush.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.

Kan,
A mild dishwashing liquid like Ivory in warm water works just fine. I lightly scrub the parts with the soapy water using an old toothbrush then air dry.

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
The instructions for Sylvan Scale Models vehicles recommend using DioSol to remove the mold release from their resin castings. I don't want that solvent in my room/lungs. What alternatives has anyone found? Will GooGone or Windex, or PineSol, or a citrus based cleaner or ??? work?
