I always clean all the door jambs, use a good Meguiars low foam cleaner at 6:1, and then Steam the front jamb door hinges, the lower hinges are especially full of leaves, dirt, crap, etc... Just stay away from the door hinge grease, and you will be fine..
The back of the door jambs, all door edges especially the bottom edges, and the middle jambs all get cleaned and wiped down...
It all has to match... If you do stellar work on the paintwork and then open the doors and see all this crap on these Jamb painted areas, will that not catch anyone`s eye???
And yes, the entire trunk - everything comes out (remember how it all goes back in), get all the dirt out of the spare tire well, etc., if it is possible, and vacuum the heck out of it.. A nice wipe down with an Apc makes it all look new again sometimes !
And yes, like Lonnie, I always remove the spare, clean it up, and air it up again.. I have never found a spare tire that is much higher than 15psi or so... How good will that work when you need it on a rainy, snowy, night???
The last part is that long big piece of carpeting... Same thing, vacuum it, you already have the Extractor out, so spray Apc, brush it in, Key the Extractor to rinse and remove all the dirt and water out...
Engine and compartment, underhood (be very careful if it has insulation, stay away from it), gets degreased, pressure washed, blown out with my MetroBlaster, let it dry as long as possible outside and then in it goes.. The next morning, spray your favorite plastic conditioner all over that engine and she also looks new again!!
New vehicle ! Inside and out !
For me, it All has to Match...
