I found a large stain that looks like oil on the back side of my driver's side visor. It's located around the mirror, not at the edge. It's about 4 inches long. Does anyone have any idea what would cause this? At first I thought the roof or windshield was leaking but the stain never dried and the headliner had no stain. Will any cleaner take it out?

 

Nothing on mine...but if it's been in for service, I would venture to guess it might have happened then. I bought some stuff at Walmart called Prestone Upholstery Cleaner for around $4.00 and it seems to get out most any stain I've tried it on...whether it's in the HHR or in the house. Worth a try anyway.
