I wonder what they used. I have two on mine I need to remove. They are subtle but I notice them.

 

i would try upholstery cleaner first.

 

I have a couple of different ones that I have used in the past (I think sodium hydroxide is the active ingredient.) I just wasn't sure if the HHR headliner material was some some odd stuff that would disappear if I used that. You can't scrub the headliner without messing up the material. I have to admit, the stuff was amazing on the gray in my 86 Turbo Regal but you could scrub it to work the stuff in.

I'll poke my head in the dealer and see what they are using. I don't want to stain the headliner trying to get it the real stain out.

 

I hear you there, let me know what you come up with. The wife and girls have makeup all over the inside of my wife's Caliber. I had some Awesome cleaner from Armour-all, it was a Purple labeled bottle instead of the traditional yellow, but I can't seem to find it anymore. My sister borrowed it and never brought it back.

 

Simple Green works on almost everything, and NO it won't leave a green stain, just a nice mint smell for a while. Used it for years, even poured gallons of the stuff inside underground tanks to remove the fuel residue before pulling tanks from underground.

 

I consider Simple Green as invaluable as duct tape. Can't live without it!

I'm in the greasy headliner from the dealer club too! REALLY PI$$ED ME OFF!! Friggin Jack Maxton Chevy monkeys! I had to take it back in, they said they steam cleaned it. It shoul have never happened in the FIRST place!
