How to Clean a Coffee Maker and Keep Coffee Tasting Fresh

A simple cleaning routine

• After brewing, discard the grounds and rinse the basket, filter holder, and carafe instead of letting coffee dry on them.
• Wash removable parts with warm water and mild dish soap, following the care instructions for your machine.
• Wipe the showerhead, warming plate, lid, and exterior only after the machine is unplugged and cool.
• Descale when the manufacturer recommends it or when brewing slows, becomes noisy, or leaves visible mineral buildup.

Cleaning and descaling are different

Routine cleaning removes coffee oils, loose grounds, and residue from the parts that touch brewed coffee. Descaling dissolves mineral deposits inside the water path. A machine can look clean and still need descaling, or have a clear water tank while the basket and carafe hold stale oils. Most brewers need both kinds of care.

Use the right product for the machine

Check the manual before running vinegar, citric acid, or any cleaner through a coffee maker. Some manufacturers recommend a specific descaling solution, dilution, or cleaning cycle, and certain materials can retain odors or react poorly to the wrong product. Never mix cleaning products, and run the required fresh-water rinse cycles before brewing again.

Pay attention to the small parts

Reusable filters, seals, valves, and the underside of lids are easy to miss. Coffee residue can collect wherever liquid slows down or splashes. Inspect those areas while cleaning, use a soft brush where the manual allows it, and replace damaged filters or seals rather than trying to scrub them back into shape.
