So. I have a child who rides in the back seat. Somehow he got a pen and drew on my headliner in black pen ink. how the heck do i remove it?! I dont want to scuff or mess up my headliner. also, I had collected a bunch of boxes for moving, and one of the corners scuffed the headliner. It's looking a little frayed and ugly. any ideas on making those look perfect would be greatly appreciated!! Thanks!
