How Do I Clean A Coffee Maker (2026)

How to Clean a Coffee Maker

The best way to clean a coffee maker is to run a cleaning cycle with a mixture of equal parts white vinegar and water, then flush it twice with fresh water. For a deep clean, disassemble removable parts and wash them with hot soapy water while running the vinegar solution through the machine.

The Short Answer

Cleaning a coffee maker requires two main steps: descaling the internal components and washing the removable parts. Fill the water reservoir with a 50/50 mixture of white vinegar and water, run a full brew cycle, let it sit for 15 minutes, then run it again. Finally, run two full cycles with plain water to remove any vinegar residue, and hand-wash the carafe, filter basket, and any other removable components with warm soapy water.

"Regular descaling with white vinegar or a commercial descaling solution every month is essential to remove mineral buildup that affects both the taste of your coffee and the machine's longevity, and you should run the vinegar solution through a full brew cycle followed by two to three cycles of fresh water to ensure all residue is completely flushed out."

The Full Explanation

Why Regular Cleaning Matters

Coffee makers accumulate mineral deposits (limescale), coffee oils, and bacteria over time. These buildup deposits reduce brewing efficiency, affect coffee taste, and can eventually damage your machine. Regular cleaning extends the lifespan of your coffee maker and ensures you're getting the best flavor from your beans.

Step-by-Step Cleaning Instructions

For Drip Coffee Makers:

• Empty the water reservoir and remove any remaining water
• Fill the reservoir with equal parts white vinegar and water
• Place an empty carafe on the warming plate
• Turn on the coffee maker and let it brew halfway through the cycle
• Turn it off and let the vinegar solution sit in the pot for 15 minutes
• Turn the machine back on and complete the brew cycle
• Empty the carafe and repeat the entire vinegar cycle one more time
• Fill the reservoir with fresh water and run two complete cycles to rinse thoroughly

Cleaning Removable Parts:

• Remove the carafe, filter basket, and any other detachable components
• Wash these parts in hot soapy water with a soft sponge
• Rinse thoroughly under running water
• For stubborn stains, soak parts in vinegar solution for 30 minutes before scrubbing
• Dry all parts completely before reassembling

For Coffee Makers with Built-In Filters:

Some modern coffee makers have permanent filters that require special attention. Rinse these thoroughly under hot water and use a small brush to clean between the mesh. For mineral buildup on permanent filters, soak them in vinegar solution for 30 minutes before rinsing.

Cleaning Frequency

Descale your coffee maker every 1-3 months, depending on your water hardness. If you have hard water, aim for monthly cleaning. Between descaling cycles, empty the carafe and filter basket after each use, and wash the carafe and filter basket weekly with hot soapy water.

What the Experts Say

Most coffee maker manufacturers, including Mr. Coffee, Cuisinart, and Bodum, recommend using white vinegar for descaling because it's effective, affordable, and food-safe. Appliance experts emphasize that vinegar is superior to commercial descalers for removing mineral deposits without damaging internal components. They also stress that the rinsing step is crucial—incomplete r
