You are probably right.


Im going to try the 303 aerospace. As long as I wont leave a gloss finish, it will be fine.

 

it leaves a matte finish, dont worry.

 

Would you be able to recommend any cleaner for the headliner? Mine is beige. Some say the Mr Clean Magic Eraser can do the trick, but maybe there are some other fabric cleaner? Even my the passenger's vanity visor is dirty (because of makeup)

 

Nope, sorry. I have no idea how to clean the headliner unless it's just lightly stained in a few isolated spots and then gently wiped with fabric cleaner or those tide on-the-go wipes.

 

I'd just steam the headliner then pat down with a microfiber.

If it's a really stubborn stain, then lightly mist some light detergent/water mix first (try woolite) and let sit 5-10 min before steaming/patting.

I use this on all my cars, house, etc etc etc. and it's one of the best purchases you can ever make in your life.

What I did when I got mine (same thing, beige headliner), was I sprayed some carpet-cleaning foam on the stain, then used a toothbrush to brush, and then took a lint-free cloth (microfiber is good too) and wiped off. Once it dries, it looks clean (unless it's a crazy stain).
