A monthly cleaning will help ensure a great-tasting cup of coffee.

Why Clean It?

Oily residue from brewing, along with hard-water deposits and other impurities, build up in coffeemakers over time. The result: Your coffee can end up with an unpleasant flavor.

How To Clean

Once a month, fill the water reservoir with a mixture that's half distilled white vinegar and half water. Turn on the coffeemaker. Let several cups run through, then turn it off and let sit for an hour. Start the machine again to complete the cycle, discarding the vinegar mixture afterward. Run plain water through the coffeemaker a few times until the vinegar odor disappears. To clean the carafe and filter basket, place in the top rack of the dishwasher.

I brew one to two pots of coffee daily so, I can just imagine the buildup of residue inside my machine. When the water dries within the tubing inside, it not only leaves hard-water deposits, it is a breeding ground for mold. I pay close attention to the time it takes for a full pot to brew. Currently, it takes about 4.5 minutes for a full cycle so, IF I notice it taking longer, I will clean it because that is an indication of buildup slowing down the process. I DO clean my coffeemaker every month to keep it clean and functional. To deter mineral deposits, not to mention, a better cuppa coffee, I use filtered water only. Because I grind my own beans, there is always an oily film in my carafe and filter basket after each pot, so I make sure to wash it with warm, soapy water and rinse it well after each use. A quick rinse just doesn't do it. If you truly want a good, healthy cuppa coffee, the key is keeping your coffee maker clean! If you want a great cuppa coffee, sprinkle a pinch (1/8 tsp.) of salt over the grounds before brewing! The salt counteracts the acidity and decreases the bitterness, leaving you with a flavorful and robust brew. Enjoy!

Running a 1/2 water and 1/2 vinegar mixture every month seems like overkill unless you've got VERY HARD WATER. I've done it about every 6 to 9 months and my coffee maker works great.

The comments here are just plain rude. Why is it we are all supposed to be PC about everything until it comes to an comment. You can be as hurtful and unfeeling as you want to be as long as no one sees your real name.

Busycoffeemom suggets a product from Williams-Sonoma but forgot to mention it costs $9.95 for a sigle use bottle. That's over $10.00 (with tax) per cleaning! This vinegar method is easy, earth-friendly and cheap. And you don't have an extra bottle, plus the other packaging to recycle. The vinegar works perfectly and really doesn't smell that bad. I use it for a ton of different cleaning jobs. Please try the vinegar method first.

I am curious why "busycoffeemom" has grease in her coffee pot... But this method has worked for me for a long time. Vinegar is cheap!

I learned the hard way that coffee machines need regular cleanings. But then I also learned the hard way that there's an easier way to clean them than water and vinegar! Though the solution works well, it's too time consuming and smells AWFUL! After trying a few products on the market, I recently learned of Full Circle at Williams-Sonoma. It quickly gets rid of the grease and grime build up on my coffee machine and is completely natural, eco-friendly and biodegradable. It's holistic and lovable!
