So i pulled another dumbass move with a company car. This time i forgot my lunch bag was in the back seat of my Accord with a can of coke in it. It has been parked since the 25th so i figured with the temps dropping i better go make sure it starts before i go back to work tommorow. I open the the door to find a coke slush up the back door and on part of the headliner. I was able to clean most of it up but i have a few stains on the head liner. Any thoughts on what to use to get the stains out?
