Removing old apple juice stains from seats?

[Kaido]

Long story short: baby car seat was removed from the back seat, year-old apple juice stains discovered.

Question: How do I remove them?

dunno about traditional means but I was just reading that if all fails, you can remove old COFFEE STAINS by pouring fresh coffee on it and soaking it up; new coffee will dissolve old coffee.

I've read that folex is a good stain remover. It's cheap and available all over the place.
