I'm trying to remove this 'grease' from the headliner of this '02 BMW 540i. The guy said it's from a bicycle tire? I tried spraying part of it with folex and rubbing gently, but not much came off. I obviously don't want to just end up turning the grease 'lines' into a grease smear...not sure what I should try. Any ideas?
Thanks, -Ash
