A good carpet shampooer should do the job. If you don't own one, rent one as they are commercial machines and much better than the ones you buy. If you have a "Home Depot" hardware store where you live then rent your machine from them and use their product "ZEP." Use the upholstery nozzle and go at it. Doesn't take much. You might as well do all the seats while you are at. Read the directions on the tank of the machine and DON'T SOAK the areas you are cleaning. It's the foam that does the trick. If you don't have a "Home Depot" then go to any large grocery store and they rent out commercial shampooers. If you keep your vehicle very clean and it's just a few spots, just buy the shampoo product, put some in a basin of warm water, take a medium small brush (even a mushroom cleaning brush will work or a tooth brush) and lightly scrub away. Then rinse well.
I found on a forum, while looking for ways to get denim stains out of a cream leather couch, that magic eraser, GENTLY and followed by soft cloth and leather conditioner will do the trick, though, I was looking into purchasing a leather couch and have not tried this myself. Otherwise, it seems people suggest upholstery/carpet cleaners work well too. Good Luck!
I've used Goo Gone to remove stains from vinyl bags before. I would test it on an inconspicuous area first to make sure it doesn't harm the finish. I used it mostly to remove surface stains and dirt, so if your stain is deep into the vinyl it might not work as well.

Many things can cause iron stains on the vinyl siding of a home. The best way to remove these stains is to use tub and tile cleaner and a cloth scouring pad.

Some vinyls will stain and there is nothing you can do to remove it. When this happens, it is usually caused by having asphalt on your shoe soles. If this is the case, the stain is in the seal coat of the vinyl and does not come out. If you try bleach, be careful of about the amount you use and how long it remains on the floor. This too, can be a staining agent over time.
I don't know why gin stains vinyl tile, but we've found that Magic Eraser does the job of removing it. However, it leaves a dull spot, so you need to apply some floor wax after removing the stain.
