Best way to remove small (oil?) stain from seat?

Hi, not sure how, but I got some little stain on my back seat and it is starting to annoy me.

I think a drop of oil leaked while I was load power tools onto the floor, not sure. I tried to take it out with 409 which usually works with no luck.

Any ideas? Its about the size of a nickle

Thanks

 

try Folex, had good results with it in my truck

Spray it with brake clean, and scrub it with a clean rag. Then don't sit on it for a day, or it might be a bit uncomfortable. This won't harm the upholstry or the foam underneath, and works great.

 

maybe simple green
