I agree with the above comments.
I would try to treat the stained area first. Another products is Grandma's Secret Spot Remover. I got mine at Hancock Fabrics but it should be at Hobby Lobby and JoAnn's.
This accident is why I'm always keeping my drinks in a small plastic (20 oz) bottle and I keep the cap on except while I'm taking a drink. I also keep a water bottle with my drink.
I've been faithful about this practice while sewing and while at the computer or laptop. They make plastic covers for your keyboards and they are very helpful for computer use.
For working around fabrics and the sewing machine (they now have computers in some of them) I try my best to be very careful with any liquids.
Let us know how you do with the stain and what you used.
Good luck with getting the stain out.
