I've noticed some dirt and stain build up on my headliner. And thanks to BigBlue, some grease/dirt hand prints up above the A-pillar when we installed my gauges. Anyone know a way to clean this stuff up? (Preferably w/out removing it)

 

Try "simple green" a brush, elbow grease, and a wet/dry shop vac. Maybe a sprinkle of H2O, that recipe has always worked on interior parts for me.

 

Windex. I'm serious. Spray some windex on there, let it soak a second, and scrub it off. I've got a bunch of bugs all over mine from running with the windows down.
