simple green & a toothbrush...as far as the fabric goes, I just reupholstered mine w/ leather instead of dealing w/ it (it smells alot better too), it was soaked completely through the foam & starting to rust the wire frame. It looked like several two-liters exploded inside. I still have it coming out of my vents in the dash when it gets hot (I'm going to pull that apart soon).
I had a detail shop steam the carpets & clean the headliner while I had the seats out...best $75 I've spent on it.
