The last owner of my car must have had some very dirty curious passengers because much of the headliner in the back was smudged and dirty as well as some on the passenger side in the front

Today I got a hold of some Blue Coral Dri-Clean upholstery and carpet cleaner. I sprayed some on a towel and scrubbed a bit at the headliner and voila, was like new again, no more dirt. Worked very well
It however unfortunately doesnt work spectacularly well on carpets (steam cleaning is best for that)


If you want to clean your headliner I can safely recommend this
