Stain removal on cloth seats

As title states, I am wondering if anyone has any good methods/products that they know of that removes stains on the tan cloth or anything, I don't want to go guessing around because, well, I just don't want to add another stain.

I don't know if it will work as well for cloth, but I got some tar out of leather with that Mr. Clean Magic Eraser. That shit does wonders I tell ya!

Is it like that pen that just removes stains?

No its similar to a really hard sponge that has cleaning agents stored in it.
