Do you notice your morning coffee tasting a little off lately? Or maybe your coffee maker just isn’t brewing as smoothly as it used to? If so, it’s time to learn how to clean coffee maker the right way. A clean machine means better-tasting coffee, fewer germs, and a longer lifespan for your favorite appliance.
Are you cleaning your coffee maker often enough? Do you know the difference between daily cleaning and deep descaling? Let’s break down the steps, tips, and tricks you need to keep every cup tasting fresh.
Why You Need to Clean Your Coffee Maker
Every time you brew, oils, mineral deposits, and coffee residue build up inside your machine. Over time, this leads to:
- Bitter or stale-tasting coffee
- Slower brewing times
- Clogged water lines
- Mold and bacteria growth
A 2011 study even found that coffee maker reservoirs are among the germiest spots in the kitchen. Regular cleaning is essential for both taste and health.
What You’ll Need
- White vinegar or coffee maker cleaning tablets
- Dish soap
- Soft cloth or sponge
- Bottle brush or small soft brush
- Fresh water
- Paper or reusable coffee filters
- Optional: Baking soda, rice (for stubborn stains)
How Often Should You Clean Your Coffee Maker?
- Daily: Clean removable parts (carafe, filter basket, lid) after each use
- Monthly: Deep clean and descale the machine to remove mineral buildup
Step-by-Step: How to Clean Coffee Maker
1. Unplug and Cool Down
Always unplug your coffee maker and let it cool before cleaning. Safety first.
2. Remove and Clean Removable Parts
Take out the carafe, filter basket, reusable filter, and any other removable parts. Wash them in warm, soapy water. Use a soft brush or bottle brush to reach tight spots. Rinse and let them air dry.
- For stubborn stains in the carafe, fill with warm water and a handful of dry rice, swirl, then rinse.
- Baking soda can help scrub away lingering marks.
3. Wipe Down the Exterior
Use a damp cloth to wipe down the machine’s exterior, control panel, and warming plate. Pay special attention to spills and coffee residue.
4. Clean the Water Reservoir
Wipe the inside of the reservoir with a clean, damp cloth. Leave the lid open to air dry and prevent mold.
5. Descale the Coffee Maker
Descaling removes mineral buildup that affects taste and performance. Here’s how:
Option A: With Vinegar
- Fill the reservoir with equal parts white vinegar and water (for tough buildup, use straight vinegar)
- Place a filter in the basket
- Start a brew cycle. Halfway through, turn off the machine and let it sit for 30–60 minutes
- Restart and finish the cycle
- Discard the vinegar solution and used filter
Option B: With Cleaning Tablets
- Add a coffee maker cleaning tablet to the reservoir and fill with water as directed
- Run a cleaning or brew cycle
- Discard the cleaning solution
6. Rinse Thoroughly
Run 2–3 full cycles with fresh water only to flush out any vinegar or cleaning solution. Replace the filter each time. This step is crucial to avoid lingering tastes or odors.
7. Reassemble and Dry
Let all parts dry completely before reassembling your coffee maker. Leave lids and compartments open to prevent moisture buildup.
