How to Clean a Milk Frother and Steam Wand (Every Type)

Milk is the messiest thing you put in your coffee setup. It dries into a film, cooks onto hot metal and quickly starts to smell sour. If you are wondering how to clean a milk frother, the rule for every type is the same: rinse or purge immediately after each use, before the milk dries, and give it a deeper clean once a week. That habit takes under a minute and prevents the crusty buildup that ruins foam and is hard to remove later.

Below you will find step-by-step methods for the four common frothers, a weekly deep clean and fixes for a clogged steam wand.

Key takeaways

• Clean right after use: fresh milk rinses off in seconds, dried milk needs soaking.
• For a steam wand, purge before and after steaming and wipe with a dedicated damp cloth every time.
• Never immerse the electric base of a jug frother or the motor of a handheld frother in water.
• Use a pin or the tool supplied with your machine to clear blocked steam tip holes, never a knife or drill.

How to clean a milk frother: which type do you have?

How to clean an espresso machine steam wand

The steam wand needs the most attention, because hot metal bakes milk on in seconds and the wand can pull a little milk back inside when steaming stops.

After every use (30 seconds)

1. Purge before steaming. Open the steam valve for a second or two into the drip tray to clear condensed water.
2. Wipe immediately after steaming. Use a damp cloth kept only for the wand. Wrap it around the wand and wipe from the top down to the tip.
3. Purge again. Point the wand into the drip tray or a cloth and open the steam for one to two seconds. This blows out any milk drawn into the tip.
4. Rinse the cloth and hang it to dry. A sour cloth makes a sour wand.

Weekly or when foam quality drops

1. Fill a pitcher with hot water, or with a milk-system cleaner made for espresso machines, mixed as directed.
2. Submerge the wand tip and let it soak for 10 to 20 minutes, or as the cleaner’s label says.
3. Wipe and purge the wand thoroughly to flush the solution out.
4. If your tip unscrews, remove it and soak it separately, then clear each hole.

Unclogging the steam tip

If steam comes out weakly or sideways, a hole is blocked. Turn the machine off and let the wand cool. Unscrew the tip if possible, soak it, then push a paper clip end, a pin or the cleaning tool supplied with your machine through each hole. Do not drill or enlarge the holes; their size controls the steam pressure. If steam is still weak, your machine may need descaling, covered in our guide on how to descale an espresso machine.

How to clean an electric jug frother

Most jug frothers have a nonstick interior, a removable magnetic whisk and an electric base.

1. Unplug and lift the jug off the base.
2. Rinse at once with warm water. Remove the whisk and rinse it separately.
3. Wash gently with a soft sponge and a drop of dish soap. Avoid abrasive pads that scratch the nonstick coating.
4. Clean the whisk seat: milk collects around the small post where the whisk sits.
5. Dry the outside and the connector at the bottom before putting it back on the base.

Check your manual before using a dishwasher. Some jugs are dishwasher-safe, many are not, especially those with a built-in heating element. Never immerse the base or any part with electrical contacts.

Burnt milk on the bottom?

Fill the jug with warm water and a teaspoon of baking soda, let it soak for 20 to 30 minutes, then wipe with a soft sponge. Repeat rather than scrubbing hard.

How to clean a handheld frother

1. Fill a glass with hot water and a drop of dish soap.
2. Switch the frother on in the glass for 10 to 15 seconds.
3. Repeat in clean hot water to rinse.
4. Wipe the shaft and whisk with a damp cloth, then let it air-dry upright.

Only the whisk and shaft should touch water. Keep the handle and battery compartment dry. If the whisk head detaches, you can soak it on its own.

How to clean a manual plunger frother

These work like a small French press, and milk hides in the mesh.

1. Rinse with hot water right after use.
2. Add hot soapy water and pump the plunger 10 to 15 times.
3. Rinse and pump with clean water.
4. Once a week, unscrew the mesh discs and wash each part, as you would a French press. Our guide on how to clean a French press shows how to take the filter apart.

Weekly deep clean and what to avoid

Signs you need a deep clean

• Foam is thin or collapses quickly.
• A sour or cheesy smell, even after rinsing.
• A yellowish film or crust on metal parts.
• Weak or uneven steam from the wand.

What to avoid

• Bleach and harsh chemicals on food-contact parts; use dish soap or a cleaner made for milk systems.
• Steel wool and scouring pads on stainless wands and nonstick jugs.
• Vinegar as a daily cleaner. It is for mineral scale, not milk fat, and some manufacturers advise against it.
• Leaving milk in the pitcher. Rinse your steaming pitcher right away too.

What to froth next

A clean frother makes the best foam for a latte or cappuccino on a bold espresso such as our Italian Roast, or a softer cup with French Vanilla coffee, which tastes sweet and creamy without added sugar. Frothers are also perfect for tea lattes: whisk our Matcha into steamed milk, or foam milk for a Masala Chai latte. Our coffee is roasted 1 to 5 days before delivery.

Milk frother cleaning FAQ

How often should I clean my milk frother?

Rinse or purge after every use, and deep clean once a week, or more often if you froth several times a day.

Can I put my milk frother in the dishwasher?

Only if the manual says so. Removable whisks and some jugs are dishwasher-safe; electric bases and handheld motors are not.

Why does my steam wand smell sour?

Milk has dried inside the tip or on the cloth you use. Soak the tip, purge thoroughly and replace the cloth.

Do plant milks need a different cleaning routine?

No. Oat and soy milks leave similar films and need the same routine.
