So I decided to try again with my couch.  And I can't believe it, but I actually got most of it out.

My biggest success came from the "goof off." I sprayed it and really let it soak in.  Then I scrubbed with a magic eraser.  I repeated the process I trillion times.

And to get the blue tint stain out I found that mixing the "goof off" with baking soda and then scrubbing with a toothbrush, really helped.

So basically I did everything to it that every leather cleaning website said not to do.

So I probably ruined the leather.

Oh well!  at least I got it off!

It's not like I could have made it any worse, right?
