Quick answer: To clean a moka pot, let it cool, unscrew it, knock out the grounds and rinse every part in warm water, then dry each piece thoroughly before reassembling. Skip detergent on aluminium pots (mild dish soap is fine on stainless steel), never use the dishwasher or abrasive scrubbers, and use a diluted white vinegar solution to remove mineral deposits.
Moka pots are cheap and last for years, but only if you look after them. Old coffee oils go stale and taint the next brew, and water left sitting in an aluminium pot causes oxidation. Here is how to clean one before first use, after every brew, and when it needs descaling or a rescue.

How do you clean a moka pot before first use?
Take the pot apart, check all the parts are there, and wash them in warm water. Then brew a few pots and throw the coffee away: Bialetti recommends discarding the first two to three brews (Bialetti NZ guide). This seasons the pot and removes any metallic taste.
How do you clean a moka pot after each use?
- Let the pot cool, then unscrew the top from the base. Hold the body, not the handle, which can break if used for leverage.
- Knock out the used grounds and rinse the base, funnel, filter plate and top chamber in warm water.
- Aluminium pots: skip the detergent. Bialetti says detergent can taint aluminium and therefore the coffee. A soft brush and warm water are enough.
- Stainless steel pots: a little mild dish soap is fine if you prefer.
- Every so often, remove the gasket and filter plate and clean underneath, and brush out the inside of the central column in the top chamber, where coffee residue builds up.
- Dry every part thoroughly with a clean towel and don’t reassemble until it is completely dry. Storing the parts separately lets air circulate and helps prevent oxidation.
Never put a moka pot in the dishwasher, and avoid steel wool or abrasive products, which damage and discolour the surface.
How do you descale a moka pot?
If you live in a hard-water area, mineral scale (mostly calcium and magnesium deposits) can build up in the base and funnel and partly block the pot. White vinegar dissolves it.
- For white deposits you can reach, scrub with a dish brush and warm water with a little white vinegar added.
- To clean the funnel, column and spout, fill the base with 1 part white vinegar to 2 parts water and brew as normal without any coffee in the basket.
- Repeat if needed, then brew once or twice with plain water to rinse out the vinegar.
- Dry all parts thoroughly before storing.

How do you clean a burnt moka pot?
If the pot boiled dry on the stove, you may be left with burnt coffee residue inside. Soak the parts in the same 1:2 vinegar and water mixture to loosen it, checking on it as it soaks, then scrub with a soft sponge or cloth. Don’t use metal scourers, which strip the protective oxide layer on aluminium. Once the residue is gone, run the vinegar mixture through the pot as above, then rinse with plain water. Check the gasket too: overheating can harden it, and a hard gasket is a common cause of a leaking moka pot.
When should you replace moka pot parts?
There is no fixed schedule. Check the funnel, filter plate and gasket for wear or damage and replace them when needed. A hard, cracked or flattened gasket won’t seal, and a clogged filter plate can make the pot sputter.
Frequently asked questions
Should you use soap on a moka pot?
Not on aluminium. Bialetti advises against detergent on its aluminium models because it can taint the metal and the coffee; warm water and a soft brush are enough. Mild detergent is fine on stainless steel pots.
Can a moka pot go in the dishwasher?
No. Bialetti says its stovetop espresso makers must not be put in the dishwasher. Wash by hand and dry thoroughly.
Why is my moka pot turning white or chalky inside?
Usually mineral scale from hard water or oxidation from being stored damp. Scrub with warm water and a little white vinegar, and always dry the parts completely before reassembling.

After soaking a whole day, the residue on the outside of the pot did not come off. I hope the inside of the pot cleans up.
Please update me on whether it works! If it does or does not please attach some photos and I will try to help!
The rubber part that surrounds the filter… Does it need to be replaced periodically? How often? How should it be washed?
Hi Sofia,
As long as it is sealing correctly it will not need to be replaced. If you notice that there is water leaking out of the sides even when screwed on tightly you may want to look into getting a new rubber gasket. You should wash it regularly and make sure there are no coffee grounds stuck underneath the gasket.
Good luck!

Thank you for this great information. My pot is stainless steel. is there anything I should be doing differently?
No these instructions should work for a stainless steel pot as well. If you want to try other mixtures you can search up different ways to descale stainless steel, but the cleaning methods should remain the same.
My husband insists that cleaning it is not great for the flavor..what is the consensus on this
It is a continuous myth perpetuated over and over again on moka pots. Clean it!
