How to Clean a Milk Frother: Whisk, Motor & Pitcher Guide

How to clean a frother: run it for 5 to 10 seconds in a cup of warm soapy water, then rinse the whisk and let it air dry. For an electric jug frother, rinse the inside with warm water and wipe it with a soft cloth. Never put the motor handle or the jug base under water. The same steps work for a milk frother and a coffee frother.

Why Is Cleaning Your Frother Important?

A dirty milk frother makes bad foam and can grow bacteria. Milk left on the whisk spring dries hard. That dried milk clogs the coils, slows the spin, and makes your next froth thin and weak. Clean your frother after every single use — it takes 10 seconds.

Warm soapy water is enough for daily cleaning. The UK Food Standards Agency says: "By cleaning with warm, soapy water or by using disinfectant cleaning products you lower the chances of getting ill." It also warns that "dirty and damp items encourage bacteria to grow" (Food Standards Agency). So wash the whisk, and then dry it.

How Do You Clean a Coffee Frother? Handheld vs Electric Jug

You clean a coffee frother in two ways, based on its type. A handheld frother is a small motor handle with a wire whisk. You run it in soapy water and rinse the whisk. An electric jug frother has the whisk inside a jug. You rinse the jug and wipe it. The motor part of both types must stay out of water.

These care steps come from our own product pages for the handheld frother with stand, the rechargeable frother and the 4-in-1 electric milk frother (links in the Sources list below). For burnt milk and hard-water marks, see our guide on cleaning burnt milk and hard-water residue. Not sure which type you have? Read handheld vs electric vs manual frothers.

How Do You Clean the Whisk?

After every use (10 seconds):

1. Fill a cup with warm water and a drop of dish soap.
2. Dip the whisk in and turn on the frother for 5 to 10 seconds. The spinning cleans the spring coils.
3. Rinse under running water. Shake off excess water. Done.

Never put the whisk in a dishwasher. None of our frother product pages lists the whisk as dishwasher-safe. Hand washing is gentle on the thin wire spring.

How Do You Clean the Motor Unit?

Never submerge the motor unit in water. The handle holds the motor and the batteries, and water inside can damage them. This is basic electrical safety for any frother.

1. Wipe the outside with a damp cloth.
2. If milk splashed onto the shaft, wipe it with a damp cotton swab.
3. For battery models: open the battery compartment and check for moisture. If any got in, let it dry completely before using.
4. For rechargeable models: keep the charging port dry, and only charge the frother when it is fully dry.

How Do You Clean the Electric Pitcher?

For the 4-in-1 electric frother with a built-in jug:

1. Pour out any remaining milk right after use.
2. Fill the pitcher halfway with warm water and a drop of dish soap.
3. Press the froth button and let it run a froth cycle. The whisk scrubs the inside walls.
4. Pour out the soapy water and rinse with clean water. Wipe dry.

Never scrub the inside with steel wool. It can scratch the inside of the jug. Use a soft sponge if needed. Do not put the base in water, because it holds the electrical parts.

How Do You Deep Clean Once a Week?

1. Baking soda soak: Mix 1 tablespoon baking soda in warm water. Soak the whisk for 10 minutes. This helps loosen dried milk and cut the smell.
2. Vinegar rinse: If you see white mineral buildup (from hard water), soak the whisk in equal parts vinegar and water for 5 minutes. Rinse well. Vinegar is an acid, so it can dissolve mineral deposits (source).
3. Check the spring coil: Look inside the coil for any dried milk. Use a toothpick to gently clear any visible clogs.
4. Dry completely: Let the whisk air dry before storing. Storing a wet whisk can lead to rust on some cheaper models.
