hi over last winter my brother left a pepsi in my back seat it froze and exploded and that pepsi hardened and its like tree sap i got it off the windows easy enough but not quite sure how to go about cleaning it from my headliner hopein some one can send me in the right direction thanks in advance.

 

I would try a steam vac,

 

I would try WD-40

 

steam it to heat it up, other than that i'd probably just replace it.

 

Get a couple spray cans of Turtle Wax "Tuff Stuff" and tell your brother to get to work cleaning up the mess or you'll beat the snot out of him.

 

i would but my brother would only make it worse i think ill just do some experimenting and if i cant ill just start pricing headliners but thanks for the suggestions and advice i appreciate it

 

brake cleaner! takes everything out wont hurt fabric
