Simple green, purple power, super clean, etc. and a scrub brush will go a long way on filthy carpet. Follow it up with a pressure washer, and you can make even the crustiest carpet passable. Make sure it is completely dry before you put it back in. Works on the seat belts too. I'll second the hand cleaner idea on the plastics. Work it in real well with a gray scotchbrite and it'll get all the gunk out of the texture on the plastic. My plastics were too faded for my liking after they were clean, so I used SEM Color Coat on them. They look like new now!
