Nothing tastes better than a fresh cup of coffee. But if your coffee machine is dirty, it can affect the flavor and even damage the machine over time. Keeping your coffee maker clean is just as important as buying good beans. One of the easiest, safest, and most eco-friendly ways to clean your coffee machine is with baking soda.
In this article, we’ll walk through why baking soda works so well, how to use it properly, and tips to keep your coffee machine in top shape.
Benefits of Cleaning with Baking Soda
Baking soda, or sodium bicarbonate, is a natural mineral that has been used for cleaning for decades. It is non-toxic, affordable, and readily available. Unlike some chemical cleaners, it won’t leave harmful residues or damage your coffee machine. It’s safe for both you and the environment.
Removes Odors, Grease, and Residue
Baking soda is mildly alkaline, which makes it great at breaking down grease, grime, and coffee oils that build up inside your machine. It also neutralizes odors. If your coffee has been tasting a little off lately, it might be because old coffee residue is affecting the flavor. Baking soda can gently lift those residues away without harming the internal parts.
Step-by-Step Cleaning Instructions
Here is a simple, step-by-step guide for cleaning your coffee machine with baking soda.
Step 1: Prepare the Baking Soda Solution
Take ¼ cup of baking soda.
Mix it with 1 liter (about 4 cups) of warm water.
Stir well until the baking soda fully dissolves.
Tip: Make sure the solution is fully mixed. If there are clumps of baking soda, it could clog your machine.
Step 2: Fill the Coffee Machine
Pour the baking soda solution into the water reservoir of your coffee maker.
Important: Only fill it as much as the maximum capacity allows. Don’t overfill.
Step 3: Run the Brew Cycle
Start the brew cycle just like you would when making coffee.
Let the machine run halfway through the brew cycle.
Pause the machine (if possible) and let the solution sit for 15 minutes.
Restart the brew cycle and let it finish.
Why pause? This gives the baking soda more time to loosen up stubborn buildup.
Step 4: Rinse Thoroughly
After the brew cycle finishes, empty the carafe.
Fill the water reservoir with fresh, clean water.
Run two to three full brew cycles with just water.
Make sure there are no traces of baking soda left.
Tip: You can smell the water to check. If it smells fresh and clean, you’re good to go.
Precautions and Tips
Avoid Overusing Baking Soda
Using too much baking soda can leave behind a powdery residue that is hard to rinse out. Always stick to the recommended ¼ cup per liter of water.
Check the User Manual First
Before using baking soda, check your coffee machine’s manual. Some brands might recommend specific cleaning agents. Although most machines are fine with baking soda, it’s better to be sure.
Don’t Forget to Clean Removable Parts
Remove and clean the coffee pot, filter basket, and any other removable parts separately. You can soak them in warm water with a tablespoon of baking soda. Rinse them well before putting them back.
Frequency of Cleaning
How Often Should You Clean?
Light Users (1-2 cups a day): Clean once every month.
Moderate Users (3-4 cups a day): Clean every two to three weeks.
Heavy Users (multiple pots a day): Clean once a week.
If you notice your coffee tasting bitter or the brewing speed slowing down, it’s a sign that cleaning is needed sooner.
Additional Maintenance Tips
Descale with Vinegar
Every three months, you should descale your coffee machine to remove mineral buildup. Here’s how:
Mix equal parts white vinegar and water.
Run the brew cycle halfway.
Let it sit for 15-20 minutes.
Finish the brew cycle.
Run two to three cycles of fresh water to rinse.
Warning: Vinegar has a strong smell, but it goes away after a few rinse cycles.
Regularly Clean Removable Parts
After every use, rinse the pot and basket. Once a week, deep clean them with warm soapy water or a baking soda soak. This prevents old oils and grounds from affecting your coffee.
Keep the Machine Dry Between Uses
After cleaning, leave the lid open so the machine can air dry. This prevents mold and mildew growth inside.
Replace Water Filters When Needed
If your machine has a water filter, replace it as recommended by the manufacturer, usually every 60 days.
Troubleshooting Common Issues
Lingering Baking Soda Residue
If you still smell or taste baking soda after cleaning:
Run two more cycles with fresh water.
You can add a slice of lemon to the water during one cycle to help neutralize any leftover soda taste.
Ineffective Cleaning
If the machine is still dirty after one cleaning:
Repeat the baking soda cleaning process.
For tough buildup, use a toothbrush to gently scrub inside parts that you can reach.
Coffee Tastes Bitter After Cleaning
If the coffee tastes odd after cleaning, it might be because of leftover baking soda or it could just be a new brew cycle adjusting. Give it another rinse and brew a “test pot” with just water.
Conclusion
Cleaning your coffee machine with baking soda is an easy, safe, and effective way to keep your coffee tasting fresh. Baking soda naturally removes odors, coffee oils, and buildup without damaging your machine. It’s affordable, eco-friendly, and simple enough to do at home.
By following the steps outlined above, checking your machine’s manual, and cleaning on a regular schedule, you can enjoy delicious coffee every day. A clean machine makes a huge difference — not just for the taste but also for the life of your equipment.
Make it part of your coffee ritual: clean your machine, brew a fresh pot, and savor the difference. Your taste buds will thank you.
