First step was gutting the trunk. This wasn't too hard, you just find all the plastic interior clips and pull them out. Then, the carpet comes out and after that is a layer of jute padding, or as someone called it, pressed lint. Also found below the carpet was this little pressed board thing for support at the edges of the trunk - I seem to be missing one and will have to make a new one. After many, many hours of cleaning, vacuuming, spraying with various cleaners, etc. I now have a clean trunk. Time to get to work!
