How to Clean a Coffee Maker
Coffee oils go rancid and water leaves limescale — both make coffee taste stale and slow your machine. A 20-minute clean every month fixes it. This guide covers descaling and cleaning for drip, espresso, and French press brewers, safely.

Buying advice
Descale monthly in hard-water areas: run a 1:1 water/descaler (or citric acid) brew cycle, then two plain-water cycles to rinse. For espresso, backflush with a cleaning tablet weekly. French press just needs hot soapy water and a scrub — no descaler. Rinse all parts well; residue tastes worse than the scale you removed.
FAQ
How often should I clean my coffee maker?
Descale every 1–3 months (more often with hard water); wipe daily; deep-clean removable parts weekly.
Can I use vinegar to descale?
Yes, white vinegar works but smells strong and needs extra rinses. A dedicated descaler or citric acid is cleaner and faster.
