@Qbenjamin , I started a thread to replace my light alcantara headliner with a dark one...haven't really gone anywhere, but many helpful replies...Honestly it isn't us, it's every time I take it to the car wash or any other place that someone gets in my car. They leave finger prints or smudges everywhere. Even had one younger guy bump his entire greasy head on the headliner. No matter how much they tried to clean it, only made it worse.
If I can find an instructional video, I'm planning to remove the entire headliner out and paint it charcoal grey. I've done this before, but those cars just had clips holding in the headliner.
Headliner - can this be replaced? Regret not getting dark headliner
if you are still interested, we can continue the research there...
