How to Clean a Coffee Maker with Baking Soda
Learn how to clean a coffee maker with baking soda using a safe, effective routine that removes mineral buildup and odors. This step-by-step guide covers drip, espresso, and pod machines, plus maintenance tips and safety notes for long-lasting freshness.

This guide shows you how to clean a coffee maker with baking soda, a safe, affordable method for mineral buildup and odors. You’ll need baking soda, warm water, and the machine’s removable parts. By following these steps, drip, espresso, and pod machines can be refreshed without harsh chemicals. According to BrewGuide Pro, baking soda is a gentle cleaner when rinsed thoroughly after use.
Why Baking Soda Is a Smart Cleaning Choice
Mineral buildup from hard water is a common challenge in coffee makers, causing bitterness, slower brewing, and cloudy carafes. Baking soda offers a gentle abrasive and alkaline cleaning action that helps dissolve mineral deposits without resorting to harsh chemicals. This makes it a practical option for regular maintenance in many homes. According to BrewGuide Pro, baking soda is a safe option for routine upkeep when used in the right ratios and thoroughly rinsed afterward. The science is simple: baking soda (sodium bicarbonate) acts as a mild base that can neutralize acids and lift mineral residues, especially when paired with warm water. It’s also widely available, inexpensive, and non-toxic when used as directed. While it works well for most drip machines, carafes, and pod systems, always consult your manufacturer’s guidance if your model has unusual components such as aluminum parts or specialized seals.
In practice, you’ll notice the difference after a dedicated clean cycle. Expect odors to fade and mineral rings to diminish, leaving you with cleaner water flow and a brighter-tasting brew. The key to success is avoiding harsh scrubbing and ensuring a thorough rinse to prevent any baking soda aftertaste. This approach aligns with BrewGuide Pro’s emphasis on safe, gentle cleaning that doesn’t compromise the machine’s interior coatings. Keep your expectations realistic: baking soda tackles buildup and odor, but it isn’t a universal solvent for all coffee maker problems. For stubborn scale, you may need a distinct descaling method that’s compatible with your unit, as outlined in later sections.

Tools & Materials
- Baking soda(1-2 tablespoons per liter of warm water; use fresh baking soda for best results)
- Warm water(Not boiling; warm to help dissolve baking soda smoothly)
- Mild dish soap(For exterior surfaces if needed; avoid abrasive pads on plastic parts)
- Soft cloth or microfiber towel(Gentle cleaning of exterior and carafe without scratching)
- Soft-bristled brush or old toothbrush(For scrubbing tight threads or carafe rims)
- Measuring spoon(To measure baking soda accurately)
Steps
Estimated time: 40-60 minutes
- 1
Gather supplies and set up
Collect all required items in one place and remove detachable parts from the machine (carafe, filter basket, and any removable reservoirs). Clearing the area reduces spill risk and ensures you can work efficiently during the clean. This step saves time later and minimizes the chance of missing components.
Tip: Having everything within reach makes the cleaning flow smoother and reduces the chance of forgotten parts. - 2
Prepare the baking soda solution
Dissolve 1–2 tablespoons of baking soda in 1 liter of warm water. Stir until fully dissolved. A smooth solution prevents gritty residues from forming during the rinse and helps lift mineral deposits without scratching surfaces.
Tip: Use warm water to maximize baking soda dissolution, but avoid hot boiling water that can warp some plastics. - 3
Remove and clean removable parts
Take out the carafe, filter basket, and any removable lids. Rinse these parts with warm water, then scrub gently with a soft cloth or brush to remove loose buildup. Dry them with a clean towel before reassembling.
Tip: Pay attention to rubber gaskets and seals; if they’re discolored or stiff, set them aside for a separate wipe-down with plain water. - 4
Circulate the baking soda solution
Pour the baking soda solution into the water reservoir or run a cycle with the solution in place, depending on your machine. Allow the solution to pass through the brew path to contact internal surfaces that commonly collect minerals.
Tip: If your machine has a pre-wet cycle, use it to ensure even distribution of the cleaning solution. - 5
Let it sit and soak
Let the solution sit for 5–10 minutes to give minerals time to loosen. This soak helps dissolve stubborn scale without scrubbing delicate components. Do not exceed recommended soak times to avoid potential residue.
Tip: Set a timer to avoid over-soaking and potential material degradation. - 6
Rinse thoroughly with fresh water
Flush the system by running 2 full cycles with clean water. This removes any baking soda residue and neutralizes taste, ensuring your coffee remains clean and free of off-flavors.
Tip: If your machine has a strong mineral odor, repeat rinsing once more to be certain. - 7
Dry, reassemble, and test
Wipe exterior surfaces dry and reassemble all parts. Run a hot water cycle once more if needed, then brew a test cup of coffee to confirm no baking soda taste remains.
Tip: Always ensure all parts are completely dry before reassembly to prevent mold growth.
Questions & Answers
Can I clean a coffee maker with baking soda on any model?
Most drip, carafe, and pod systems respond well to baking soda cleaning, but always check your manufacturer’s guidelines before proceeding. If your machine has specialized coatings or metals, use the recommended cleaner or descaler instead.
Most machines respond well, but always check the manual first.
Will baking soda leave a taste in my coffee?
If you rinse thoroughly with clean water and run one or two extra water cycles, a baking soda taste should not remain. Spent cycles and proper drying help prevent any aftertaste.
Rinse well and run extra water cycles to remove any residue.
Is baking soda safe for stainless steel internals?
Baking soda is generally safe for stainless steel when used in appropriate dilutions and fully rinsed. Avoid abrasive scrubbing that could scratch surfaces.
Safe when used gently and rinsed completely.
How often should I perform a baking soda clean?
For households with average water hardness, every 1–3 months is common. If you have very hard water, you may do it more frequently.
Every 1–3 months usually, depending on mineral buildup and usage.
What if my coffee maker has a plastic interior?
Use a mild solution and avoid harsh chemicals. Rinse thoroughly and dry completely to prevent odors or residue.
Use mild cleaner and thorough rinsing to protect plastics.
Key Takeaways
- Use baking soda for a gentle mineral-clean when rinsed well.
- Rinse cycles are essential to avoid aftertaste.
- Test in a small area on first use and avoid aggressive scrubbing on plastics.
- Maintain a regular cleaning schedule to prevent scale buildup.
- Always dry parts completely before reassembly.
