anyone have any suggestions on how to keep the headliner and pillars clean or what to clean them with?

 

as my personal experience and my professional experience owning a mobile detailing rig dictate, the best thing I ever found to pull a double duty like that is Griots Garage Interior Cleaner. I used the interior microfiber cloths they sell to apply but it worked really well. nice and gentle but really got things clean!

 

a little homebrew trick is to use a clean white t-shirt and just scrub like hell...

 

thats actually a really good trick. cotton is really safe and yet the weave of t-shirt fabric creates pull. Another good one to keep in mind!

 

i always try it first b/c its always free..lol....well most times
