How to Clean a Moka Pot
Let the pot cool, take it apart, and rinse all three parts with warm water only. For a classic aluminium pot, skip the soap and the dishwasher — both ruin the taste. Dry everything fully and store it unscrewed. To descale, brew a 50/50 water-and-vinegar mix through it, then rinse.
Cleaning a moka pot properly is the single easiest way to keep it making great coffee for decades. The good news: it barely takes a minute, and the biggest mistakes are things people do with good intentions — scrubbing it shiny, blasting it with soap, or running it through the dishwasher. This guide covers the right daily routine, how to deep-clean a stained or smelly pot, and how to descale it, for aluminium and stainless-steel models alike.
How to clean a moka pot after every use
This is the routine that matters most. Do it after every brew and you'll rarely need anything more.
- Let it cool completely. Never rinse a hot moka pot under cold water to clean it (a quick cool of the base to stop extraction is fine, but full cleaning comes later). Let the pot cool so you can safely unscrew all three parts without burning yourself or warping the metal.
- Disassemble all three parts. Separate the bottom boiler, the funnel-shaped filter basket and the top collecting chamber. Lift out the rubber gasket and the metal filter plate from under the top section so you can rinse behind them.
- Tip out the grounds. Knock the spent puck of coffee out of the basket into the bin or compost, not the sink, where it can block the drain. A quick tap on the side of the caddy is usually enough.
- Rinse everything with warm water. Rinse all the parts under warm running water and wipe them with a soft cloth or non-abrasive sponge. For a classic aluminium pot, skip the washing-up liquid entirely, as it strips the seasoning and taints the taste.
- Dry every part thoroughly. Water left sitting in an aluminium pot causes white oxidation and, over time, corrosion. Dry each part with a tea towel and leave them on the rack until bone dry.
- Store it unscrewed. Reassemble loosely or leave the pot in its three parts with the lid open. Storing it screwed tight and damp traps moisture against the gasket and encourages musty, stale smells.

Should you use soap? (The seasoning question)
For a classic aluminium moka pot like the Bialetti Moka Express, the answer is no. Over time a thin layer of coffee oils builds up inside — the "seasoning" — and it genuinely improves the flavour, rounding off the sharp, metallic edge a brand-new pot can have. Washing-up liquid strips that layer away and leaves a faint soapy taste in the next few brews. Warm water and a soft cloth are all you need.
Stainless-steel and induction pots don't season in the same way, so a little mild washing-up liquid is fine, and many are dishwasher-safe. Even then, hand-washing is gentler and makes them last longer.
How to deep-clean a stained or smelly moka pot
A darkened interior on an aluminium pot is normal and good — leave it. But if the pot smells stale, tastes off, or has visible burnt-on residue, give it a deeper clean:
- Stale smell or taste: take it fully apart and rinse every part, paying attention to the underside of the filter plate and around the gasket, where old oils hide. Dry completely and store it open.
- Burnt-on coffee: fill the boiler with a 50/50 mix of water and white vinegar, run it through as if brewing (no coffee in the basket), then rinse thoroughly.
- White powdery marks (aluminium oxidation): wipe with a cloth dipped in a little vinegar, then rinse and dry. Prevent it by never leaving water sitting in the pot.
Avoid steel wool, scouring pads and abrasive powders on any moka pot — they scratch the surface and, on aluminium, remove the protective layer.
How to descale a moka pot
If you're in a hard-water area, limescale builds up in the boiler and around the valve, slowing the brew and eventually clogging things. Descale every month or two:
- Fill the bottom chamber with equal parts water and white vinegar (a citric-acid solution also works).
- Assemble the pot with an empty basket and heat until it brews the mixture through.
- Discard the liquid, rinse every part thoroughly with warm water, and run one plain-water brew to clear any vinegar taste before making coffee.
Replacing the gasket and filter
The rubber gasket and metal filter plate are wear parts. When the gasket hardens, cracks or the pot starts hissing steam from the seam, it's time for a new one. On a Bialetti and most major brands they cost only a few pounds and take seconds to swap — lift the old gasket out from under the top chamber and press the new one in. Fresh seals are the difference between a pot that leaks and one that brews cleanly for years.

Frequently asked questions
Should you wash a moka pot with soap?
Not if it is aluminium. Rinse a classic aluminium moka pot with warm water only, as washing-up liquid strips the natural seasoning that builds up inside and leaves a soapy taste. Stainless-steel and induction models tolerate a little mild soap.
Can you put a moka pot in the dishwasher?
Aluminium moka pots should never go in the dishwasher; the detergent and heat dull the finish, cause oxidation and ruin the taste. Many stainless-steel models are dishwasher-safe, but hand-washing extends the life of any moka pot.
How do you clean a burnt or stained moka pot?
For burnt-on coffee, fill the boiler with equal parts water and white vinegar, run it through as if brewing, then rinse well. For light interior staining on aluminium, leave it; a darkened inside is normal seasoning and helps the flavour.
How do you descale a moka pot?
Fill the bottom chamber with a 50/50 mix of water and white vinegar (or a solution of citric acid), assemble without coffee, and heat until it brews through. Rinse thoroughly and run one plain water brew before making coffee again.
How often should you replace the moka pot gasket?
Replace the rubber gasket and filter plate roughly every 6 to 12 months, or sooner if the seal cracks, hardens or the pot starts leaking steam from the sides. Both parts are cheap and widely available for Bialetti and most other brands.
Why does my moka pot smell or taste stale?
Usually because oils have built up and gone rancid, or the pot was stored damp and screwed shut. Rinse every part thoroughly after each use, dry it fully, and store it unscrewed with the lid open.
The bottom line
Cleaning a moka pot comes down to three habits: rinse with warm water (no soap on aluminium), dry it fully, and store it unscrewed. Descale occasionally, replace the gasket when it wears, and never reach for the dishwasher or a scouring pad. Do that and a £30 pot will outlast almost everything else in your kitchen.
