Coffee stains are a fact of life if you weren't born with the balance of a gymnast. Since I drink coffee almost every day and have no sense of balance to speak of, the number of times I've spilled coffee on myself, or something in my immediate environment, numbers in the thousands, if not more.
And since these coffee stains usually happen to me in the wild — on the train, in the middle of a restaurant meal, or en route to run errands — I usually don't have the option of tossing something in the washing machine until the end of my day. Not to mention, if stain removal were just a matter of doing a load of laundry, none of us would need hacks on how to remove them.
