What product to clean a spot on a headliner?

[Brett K]

My wife’s ne Lincoln has a spot on the beige headliner where it looks like someone touched it with some dirt on their hand. I assume i want to try something mild that won’t discolor it. I am worried about making it worse and leaving a water mark behind if I get it too et.

Try a lightly damp microfiber towel and spray an apc into a corner of the towel. Lightly wipe away at the dirty spots until they come off. Then lightly wipe the area again with a part of the towel that has no apc on it.
