I have a few spots on my beige celing of my car. What do you guys use for cleaning. I know that is a very sensitive material

 

I just finished detailing my interior and I went to Autopia and did a lot of research on headliners...mine was pretty clean but I did clean it since it hit the two year mark. I got Woolite Foam Upholstery cleaner and sprayed it directly on a Microfiber towel. I made sure to have very little foam on the mf towels and used it to clean the headliner gently. Be sure to have a damp (really lightly damped) towel so that you can rinse off the cleaner.

Be gentle and it should be fine. Also, I read that a 6:1 ratio of Woolite fabric wash to water is also a good cleaner to use. Be more careful though since it is a liquid detergent. The Woolite Foam Upholstery cleaner is pretty dry.
