Got my car back from the alarm installer, 4th time now, and the headliner has a bunch of black fingerprints on it. Most are where the pillars intersect the roof. Any tips on cleaning the headliner? Products? Do and dont's?

Thanks!

 

that sounds very unprofessional who installed the alarm if they should be paying the cost to have it detailed and cleaned.

 

I would first complain to the company manager. If that doesnt work: You will need a mircofiber rag and a can of Aerosol shampoo. You should be very careful not to get the headliner too wet because it may cause they glue to lose its stickyness. 1) spray some shampoo on your rag. 2) Gently rub the area. 3) Repeat.
