I have looked through several Pages here to see if anyone has some good thoughts about cleaning the Headliner. I just bought this 2008 Model and it is evident that the previous owner loved driving through fields and dirt roads with all of the windows down. There is a slight smell in the truck so I was told to address the carpet and the headliner. I think I will just replace the carpet with OEM for about $450. But the headliner cost $1100 !! So I will just do a clean/vacum job on it and hopefully improve or eliminate the smell. I know the headliner is a thin fabric so I was curious if any of you have any suggestions with this project. Thank-you.
