How to Clean a Bialetti Moka Express

Updated April 17, 2017

For authentic Italian espresso, many Americans turn to their Bialetti Moka Express, a hob espresso-maker that uses steam and pressure to create aromatic, richly flavoured coffee. In order to keep a Moka Express functioning like new, coffee drinkers must carefully clean and dry it between uses. The pot is made of aluminium, which retains a thin layer of coffee-bean oil from previous brews and adds a complexity to the taste of its espresso. Aluminium pots corrode when they are not properly cared for, so Bialetti Moka Express owners should clean their pots attentively.

Allow your Moka Express to cool after you have poured out your pot of espresso. Disassemble the pot, separating the coffee pot on top, the gasket and filter screen, the filter full of used grounds and the water tank that sits on the stove.

Turn the funnel upside down over a dustbin and tap it gently with a spoon to remove the grounds. Tap the base of the funnel rather than the rim, which is delicate.

Rinse all the pieces with cool water. Use a mild liquid dish soap if you wish, or use water alone. Do not use soap on the coffee pot itself if you want to keep the layer of oil to flavour future brews.

Dry all the pieces gently with a soft cloth. Store the Moka Express in pieces, so no residual water droplets can become trapped inside and corrode the aluminium.


Never wash your Bialetti Moka Express in a dishwasher. Do not scrub any of the pieces or use harsh detergents. If you choose to leave the layer of oil in the coffee pot and it begins to smell, fill the water tank with water and a small amount of liquid dish soap and boil it as you would to make espresso. When all the water has travelled into the coffee pot, remove it from the stove and rinse it thoroughly.
