How Do You Fix a Coffee Stain?

Today I made instant coffee in my dorm for the first tin my life the coffee bubbled over and landed on my roommates white and blue seat cushion. How do I clean it? I’m not afraid to tell her, it was an accident and she’s pretty understanding, I just want to clean it because I was the one who made the mess

cold water and a lot of white paper towels—blot ,blot blot with damp (not dripping) towels-cold only or you’ll set the stain—after it looks like you got it all a bit of soapy water–againdabbed ,blotted on—clear cold rinse
