I usually start with lukewarm water and dish wash. I don't see the need for distilled water here. Why? Regular water won't harm any plastics, bakelite or circuits... If soapy, lukewarm water still leaves unwanted coloring (tar from cigarettes is very common) I use IPA. If that fails too I, very carefully, try using something like naphtha. Acetone is a last resort but beware: using it on any kind of plastic may result in unrecoverable damage.
