If you want them to look like they just came out of the factory, get an ultrasonic cleaner and the degreaser concentrate. I bought one a while back and decided to clean some 1/10 scale RC car parts in it since I was trying to get all the grease out of the nooks and crannies and even a toothbrush was having a difficult time with it.
The parts came out looking brand new, like I had just pulled them out of their original packaging.

Can see it now; Honey A. Mad Hatter says we need an ultrasonic cleaner… :)
