I borrowed a book from a coworker and accidentally spilled some of my strawberry banana smoothie along the bottom of the book. I would prefer to return the book to my coworker stain free. Is there a way to do this? I've heard of using chlorine or cream of tartar, but I'd like to hear what y'all suggest.
More info: the book is not terribly old. It was published in the 90's.
Any advice would be appreciated!
