How clean is the coffee that comes out of your machine? That depends. A better question is how clean is your coffee maker? Some people think because the coffee itself is hot, that it kills all the bacteria and their cup of joe is automatically sanitary. But if you don’t clean your coffee maker, you could actually be drinking coffee that’s not exactly appetizing. Your machine could even contain mold or other nasty bacteria.

Moist and wet environments are ideal places for yeast and mold to grow. A study byNSF Internationalfound that 50 percent of households had yeast and mold in the reservoir of their coffee maker. WhenCBS Newsswabbed 11 household coffee makers, they found 11 different types of bacteria, including pseudomonas aeruginosa (a bacteria that grows in standing water) and enterobacter bacteria (a coliform bacteria that’s present in the human colon).

Grossed out yet? If cleaning your coffee machine isn’t a part of your chores, you may want to make it a part of your cleaning regimen. Here’s how to properly clean your standard-drip coffee machine.

What you’ll need

You don’t need anything special to clean your coffee machine, just a few items you probably already have around the house.

Step 1: Remove the coffee maker’s filter

Start off by removing your machine’s reusable filter (if applicable). Then, soak the filter in a solution of distilled water and a squirt of mild dish soap for 20 minutes. Then, give it a good rinse under water to remove any soap residue. After you’ve rinsed it thoroughly, leave the filter out on a drying rack, and allow it to dry completely.

Step 2: Create a cleaning solution and run it through your coffee machine

Mix one cup of vinegar with one cup of distilled water to create a cleaning solution. For smaller coffee makers, you’re able to use one-half cup of vinegar and one-half cup of water. Pour this solution into the water tank, and let it sit for about 20 minutes. This will help clean some of the funk that’s sitting in the bottom of the water tank.

After the 20 minute time period passes, turn on the coffee machine and brew the vinegar and water solution through your machine. Once it brews through into the pot, swirl the hot vinegar and water solution around your coffee pot, and then discard the solution.

Brew two cups of distilled water in your machine to help eliminate any vinegar residue. Mix the hot water in the coffee pot, and then drain the water out of it. Do this process again and again until the vinegar smell completely goes away.

Step 3: Clean your machine’s exterior

Wipe down the outside surface of the machine using a clean sponge ordisinfecting wipes, baking soda, and distilled water. you may also use dish soap to eliminate any coffee discolorations. After you do this, rub your machine with a cloth and water to clear off any remaining baking soda or soap deposits. After you’ve finished washing off the outside of the machine, keep the lid off of the water tank. Separate the cover from the coffee pot and let your coffee maker dry completely.
