I use 3D Products Instant Shine, but there are a variety of methods to restoring black plastic, like using a heat gun, or black dye. If you do use Super Clean Degreaser, put the pieces in a plastic container and let it soak at minimum 3 hours or overnight in the garage or outside. Use an old toothbrush if you have to to brush the old paint off. People who build/paint plastic models/figures have been using this stuff for years as a paint stripper for small plastic pieces.
