Though I have a 2004, I asked the factory specifically what I should use and the response I got was to use mineral spirits. I did and it took the gunk right off. Of course, I took all the stickers and pinstripes off first and only had to remove the residual glue. I then washed off the areas where I did the work. Looked great.
Whatever you do, and whatever you use, do NOT get it on or near rubber, caulked areas, plastics, etc....in most cases, the same stuff that works so well getting the gunk off, can also remove and/or damage these other ancillary materials.
Computers manufactured by companies such as IBM, Compaq and millions of others are by far the most popular with about 70 million machines in use worldwide. Macintosh fans note that cockroaches are far more numerous than humans and that numbers alone do not denote a higher life form. -NY Times 11/91
