[Backtobasics]

I have great luck with Simple Green and a pressure washer.

I bought a Suburban a while back, and the interior was FILTHY. I gutted the inside, stretched the carpet over saw horses, and presprayed everything in simple green. All door panels, interior plastics, seats, etc. I pressure washed everthing, and while it dried I got to everything I could get to inside including floor, dashboard, etc.

Once it dried, I reassembled. Not only does the interior look like it did in 1994, but the faint smell of simple green is in the air.
