Ok, so I finally cleaned my headliner.
I used a diluted Woolite/Zero and a white cotton T-shirt and gently rubbed away the dirt. Now I've never really cleaned the headliner before (for 8 years to be exact) but by the end of the cleaning the T-shirt was black! I can't believe that much dust was collected over the years.
Well, I'm happy it's clean now.
