Well done, JB. I have a couple things I might want to add to this...in my reading I may have missed them if they were there:
1) I think Plexus does such a superb job of cleaning the clear plastic of the instrument panel and the delicate plastic on the climate control/radio screens, that it deserves special mention
2) Some of the storage bins are lined with rubber bottoms. These can be removed, treated, put in ziplock bags, and installed just prior to the event.
3) Any mention of removing the bumperettes for treating and cleaning underneath? I see you do the license plates.
4) I think you may as well go ahead and tell people they need to remove their wheels. It really is the easiest way to effectively clean the wheelwells and alloys.
I can't think of anything else at the moment. That is a huge list and has covered at least a dozen areas I hadn't even thought of!
Great job!
