I didn't take pictures, but should have. I had some dirt on the headliner from when I purchased the car. Mostly on the driver's side, around the sunroof/etc. Anyone knows that water or a spray cleaner generally makes things look worse. Well, I saw this on another forum, and gave it a try (especially since I've used it for cleaning around the house with amazing results.

It really works great. Rub GENTLY if you do try this.
