Keurig cleaners
Yes: A cleaning solution for those single-serve coffee makers is now being marketed. A friend was shopping when an elderly man asked for help with the directions on a $13 bottle of Keurig cleaner. Should he use the entire bottle, all at once?
Yes, she said, and no: “I told him to go find the vinegar aisle and try that first.” Don’t waste your money on a special cleaner. Take our friend’s advice and use vinegar, which is magic. (It works on multicup coffee makers, too.)
