I have heard several ways to clean resin castings and they are all basically the same but my German thirst for detail requires me to ask some questions.
The way to clean the castings is to use detergent. Will normal dishwashing liquid do for this?
How long must I soak the castings before scrubbing them with a soft brush?
After cleaning, they must be assembled. What keeps them clean until a coat of paint is applied?
Thanks for your patience,
Regular dish detergent should work fine as most release agents are some sort of grease/oil based substance. Washing the model similat to the way you wash dishes should be enough. I occasionally clean the model with a spray degreaser such as 409, a product here in the states. Something to keep in mind. as the mold rubber/resin industry has evolved, the products have gotten better. I cast resin all of the time and do not use any mold release in my silicone based molds and have never had a paint adhesion problem. I also assemble kits from a lot of the popular manufacturers and rarely ever wash them prior to paint. I have never had a paint job fail. I only recall one model ever that had release agent on it.

Probably the biggest concern is getting skin oils on them and the way around that is to wear rubber gloves. You can either buy rubber gloves sold for dishwashing in the grocery store or latex gloves similar to medical gloves. I get packages of them called “Hy-Five” from Canadian Tire. The latex gloves allow for more dexterity.
Good way to find information. Probably more than you want to know.

Then how do you get the soap off?[:P]
I like those white fabric gloves that you can get at art stores if you’re not spraying or te like, not so sweaty. BILL
Good info, as I just bought my first resin kit, a station model from Funaro and Camerlengo. Looks like all 4 walls have a bit of a warp to them, the two roof pieces, the largest area pieces in the kit, are strangely enough not warped.
