I will give you my advise from my experience.
My first Mac was a 128k purchased in January 1984. I upgraded and continued using that box until I purchased a Mac IIvx in 1993. I started buying compacts again several years ago. I frequently had need to clean the housing. What I found most effective, event to this day, is 409. Spray a lot of it on one side and leave it there for 15 minutes. Obviously, doing this in the evening or otherwise out of direct sunlight is best. Leaving it to just sit on the plastics let's it really pull out dirt, grime, pen marks -- you name it! Then wipe it with a rag. Sometimes you may need to do this twice. I've had very nice results, even on cases where stickers had been applied.
The next step up from 409 is LumpyBright -- my name for our very own LumpDog's low-H202 version of RetroBright. You can read about my experience, which was based on Lumpy's earlier work, in this deyellowing thread.
So give 409 a chance and if you want more, go with RetroBright.
