Does anyone have any suggestions on how to best clean grease/dirt off a crema headliner?
I think that the grease/dirt came from the top mechanism (which begs the additional question, "How does one prevent the mechanism from doing that again?)
I have read about using steam, extractors, chemicals, etc for cleaning upholstery, which seems to be analogous. While many of these methods seem to remove the grease from the original spot, there is a tendency for the chemical and grease to wick to the adjacent areas, thereby discoloring them.
