Clean your coffeemaker at least once a month to ensure a great-tasting cup of coffee every morning, and to keep it in good working condition for a long time. An inexpensive, easy and natural way to clean a coffeemaker involves the use of vinegar and water. The acidic vinegar gets rid of undesirable buildup, paving the way for your favorite morning wake-me-up.
Mix equal parts of white vinegar and water, then pour the mixture into your coffeemaker. Do not exceed the maximum quantity of water allowed for your coffeemaker.
Put in an empty filter, then turn on the coffeemaker.
About halfway through the brewing cycle, turn off the appliance and let it sit for 30 minutes.
Turn on the coffeemaker to finish the cleaning cycle.
Run several cycles of fresh water through the coffeemaker to eliminate any remaining vinegar.
