With the right stuff, you could probably get some (or most) of it back to normal. I try to avoid most chemicals (and wiping with any type of towel). At home, I use the wife's bissel carpet steamer wand attachment and instead of using carpet cleaner for the house, I use the Chemical Guys carpet cleaner (about 12 bucks for a bottle and it doesn't take much at all to do the entire car). It did wonders for my carpet, especially the soda/candy/who knows what else stains across the back floorboard from the kiddos that never listen when you tell them not to have junk in there... There may be better stuff out there; my experience with carpet isn't very extensive. But that worked for me, and it was cheap.
