Removing KFC grease from fabric seat

[jamei303]

Someone who shall remain nameless managed to dribble their hot KFC oil over the fabric passenger seat. I said no eating in the car but you know how it is

Last time I tried a car seat fabric stain remover was a good few years ago and I can't remember the brand, but it made it worse.

Any suggestions? According to their website it'll be rapeseed oil mixed with chicken fat.
