Here’s The Gross Reason Why You Should Deep Clean Your Coffee Maker


Do you ever clean your home coffee maker, or do you just rinse it out and leave it on the counter?

One mom is wondering if her coffee brewer may be causing her health problems, after opening it up and discovering something very unpleasant inside.

Morning cup leaves bad taste

Stephanie Brauns loves coffee, but for the past six months she’s been having a bad reaction to her morning cup of Joe.

“It’s interesting because I always have my coffee at home, and within three sips, I sometimes have severe reactions,” she said.

So when a friend forwarded her some articles about mold and bacteria in coffee pots, this busy human relations manager brought her coffee maker to work and opened up the top with a screwdriver.

“It was horrifying,” she said. “Horrifying is what was my reaction was.”

She couldn’t believe what was under the top: Several years of calcium buildup, along with a brownish-yellow substance that looked like mold.

Some hard to clean and dry

Some coffee makers are very easy to clean, as you get a glass carafe and a very simple to clean tank. But Braun’s machine is not one of those.

“It is impossible to get to the full tank unless you dismantle this machine, which I haven’t figured out yet,” she said. “Outside of taking a hammer to it, I don’t know how to completely open it and see what’s inside.”

She is sending a sample of the buildup in the top section to a lab to see if anything toxic may be growing there.

What you can do

What can you do to protect your family?

Most brands instruct owners to clean the machine regularly with white vinegar: It dissolves crud and helps disinfect the inside.  Even pod machines need to be cleaned regularly (check your machine’s handbook).

Good Housekeeping Magazine says “just washing the carafe won’t cut it.” It suggests that you run a vinegar cycle monthly, then empty the tank completely, and leave the lid open to dry for a day. Read their suggestions here.

Here’s a video from Real Simple showing an easy and quick way to clean your coffee maker.

That way you get out the buildup, and prevent mold from growing, and you don’t waste your money.
