With a few household items and about 30 minutes, you can have your machine running like new.
How to Clean Drip Coffee Maker
This is your complete, step-by-step guide. We’ll cover everything from the quick daily wipe to the deep monthly clean. Following these steps will remove mineral scale, old coffee oils, and hidden grime. You’ll be amazed at the difference in your coffee’s flavor. Let’s get started with what you’ll need.
What You’ll Need for Cleaning
You likely have most of these items at home already. Here’s your checklist:
- White vinegar or a commercial descaling solution
- Fresh, cold water
- A soft sponge or cloth
- A small brush (an old toothbrush works perfectly)
- Mild dish soap
- A measuring cup
- A clean paper towel or lint-free cloth
Step-by-Step Deep Cleaning Process
Perform this deep clean every one to two months, or more often if you have hard water. It descales and decalcifies the internal heating element and water tubes.
Step 1: The Vinegar Solution Rinse
First, make sure the coffee maker is off and completely cool. Discard any old coffee or filters. Fill the water reservoir with a mixture of half white vinegar and half fresh water. For a standard 12-cup machine, this is usually about 4 cups of vinegar and 4 cups of water. If your water is very hard, you can use a stronger ratio, like two-thirds vinegar.
Step 2: Run a Brew Cycle
Place a clean filter in the basket. Put the empty carafe back on the warming plate. Now, turn on the machine and run a full brew cycle as you normally would. Let the vinegar solution run completely through the system and into the carafe. This process dissolves the mineral scale inside.
Step 3: The Clear Water Rinse
This step is crucial. You must remove all traces of vinegar. Empty the carafe of the hot vinegar solution. Rinse the carafe thoroughly. Fill the water reservoir entirely with fresh, cold water. Place another clean filter in the basket. Run a full brew cycle again, discarding the water from the carafe when done.
Step 4: Repeat the Rinse (If Needed)
If you can still smell vinegar after the first clear water cycle, repeat Step 3. Run another full cycle with just fresh water. It’s important that no vinegar scent remains, as it will affect the taste of your next pot of coffee.
Cleaning the Removable Parts
While the water cycles are running, you can clean the individual components. This makes a huge difference in flavor.
The Carafe and Lid
Wash the carafe and it’s lid with warm, soapy water. For stubborn coffee stains, use a paste of baking soda and water. Let it sit for a few minutes before scrubbing gently with a non-abrasive sponge. Rinse thoroughly. Never use harsh scouring pads, as they can scratch glass and plastic.
The Filter Basket and Brew Head
Remove the filter basket and any permanent filter if you have one. Wash these with soapy water. Use the small brush to scrub the brew head—that’s the small showerhead that disperses water over the grounds. Coffee oils and grounds can clog the tiny holes. A clean pin can help clear any stubborn blockages.
The Warming Plate
Wipe the warming plate with a damp cloth while it is completely cool. For baked-on stains, dip the cloth in a vinegar solution to help loosen them. Be gentle to avoid damaging the heating element.
Exterior and Final Wipe-Down
Wipe the entire exterior of the machine with a damp cloth. Don’t forget the water reservoir lid and the handle area. Dry everything with a clean towel. Leave the lid open for a while to let the interior air out and dry completely. This prevents mildew growth.
Maintaining a Clean Machine Between Deep Cleans
Daily and weekly habits keep your machine fresh and extend the time between deep cleans.
- After each use, rinse the carafe and filter basket.
- Wipe the brew head with a damp cloth weekly.
- Leave the lid open after use to air out the reservoir.
- Change your water source if possible; filtered water creates less scale.
- Always use a fresh paper filter or clean your permanent filter after every use.
Troubleshooting Common Problems
Even with cleaning, issues can pop up. Here’s how to fix them.
Persistent Vinegar Smell
If the vinegar odor won’t go away, run two more clear water cycles. You can also run a cycle with just baking soda (4 cups water mixed with 1/4 cup baking soda), followed by two clear water cycles. The baking soda neutralizes odors.
Slow Brewing or Dripping
This is usually caused by clogs. Check the water reservoir exit hole and the brew head for mineral deposits. Use a toothpick or pin to carefully clear them. Also, ensure you’re using the correct grind size; too fine a grind can clog the filter.
Coffee Tastes Bad After Cleaning
This means residue was left behind. Run several more clear water cycles. Always ensure you use a clean cloth for wiping, as detergent residue from a sponge can also cause bad tastes.
Why This Process Matters
Regular cleaning does more than just improve taste. It directly effects the lifespan of your appliance. Mineral scale acts as an insulator on the heating element. This makes the element work harder, use more electricity, and eventually burn out. The oils from coffee, called cafestol, go rancid over time. This is the primary source of bitter, sour flavors. A clean machine is a efficient, tasty, and reliable one.
FAQ Section
How often should I clean my drip coffee maker?
You should do a deep clean with vinegar every 1 to 2 months. If you use hard water or make coffee multiple times a day, aim for once a month. Always do a quick rinse of the carafe after every use.
Can I use lemon juice instead of vinegar to clean my coffee machine?
Yes, you can. Lemon juice contains citric acid, which also breaks down mineral deposits. Use the same ratio: half fresh lemon juice and half water. However, vinegar is often more effective and less expensive for this specific task.
What is the best way to clean a coffee pot with stubborn stains?
For a glass carafe, make a paste of coarse salt and ice cubes. Swirl it around aggressively; the abrasion of the salt and the temperature shock helps lift stains. For plastic parts, a soak in a warm water and baking soda solution for 30 minutes before scrubbing is very effective.
Is it safe to run vinegar through my coffee maker?
Absolutely. Running a vinegar solution is the standard method recommended by most manufacturers. The key is to follow it with multiple clear water rinses until no vinegar smell remains. This ensures no taste transfer to your coffee.
Why does my coffee taste bitter even after cleaning?
Bitterness after cleaning can have a couple causes. First, you may not have rinsed all the cleaning solution out. Run two more clear water cycles. Second, the bitterness might be from your coffee beans, grind size, or brew time, not the machine itself. Experiment with those variables too.
Can I use dishwasher to clean my coffee maker parts?
Check your manual first. The carafe and it’s lid are often dishwasher safe on the top rack. However, the main unit, filter basket (if plastic), and warming plate should never be submerged or put in the dishwasher. Hand washing is safest for most components.
