Headliner cleaning ???

[tmunn]

What do you guys use to clean that textured moon crater of a headliner ?
Any product or process would be appreciated.

On a Mustang that still has the original headliner, would let it go as it doesn't need
much to split open a seam. At least on a warm weather Mustang.

And along that same train of thought, you don't want to use any harsh cleaner or anything containing bleach, as it'll soak into your threads and cause premature failure...

I used Simple Green and damp sponges. Light pressure and a lot of time.
