I have just bought my first 3D printed models, and I was wondering what kind of prep work people use to get them ready for painting?

I am used to more standard HiPS and Restic (re: Sedition Wars, the new Kickstarter Battletech models) plastic models, in which I give them a brushing with a toothbrush soaked in Isopropyl Alchohol to remove any kind of mold release agent, as well as finger grease. It also kind of "dries them out", and they seem to take primer better than with just normal soap and water.

These first two models are some Battlemechs I bought from Etsy, and they have kind of a "filmy" feel to them. Will the same Iso treatment work fine on them to remove that? Or does anyone thing different?

If they have a sort of film on them, whoever printed them did a bad job at cleaning them.
I would immerse them in alcohol for maybe 20 seconds and then scrub them with a toothbrush, rinse them in a little more alcohol, and let them dry.

Thanks for the advise. I used 91% ISO and a toothbrush like on my normal minis, and it cleaned them up no problem. Now they feel perfectly dry and matte to the touch. Now on to painting, and then watching them get soundly beaten on the tabletop, lol.
