- Battery life: One full charge provides roughly 60 - 80 uses, depending on speed setting and frothing duration.
Tip: Do not charge the frother while it is running. Always turn it off before plugging in the USB cable.
How to Replace Batteries (Battery Edition)

Pro tip: Use high-quality alkaline batteries for consistent speed and longer life. Rechargeable NiMH batteries also work well if you prefer a greener option.
How to Replace the Whisk
Pull the old whisk straight down from the frother shaft. It is held by a friction fit - no tools needed. Align the new whisk with the metal shaft. The whisk stem has a small notch that slots into the shaft. Push the new whisk upward until it clicks into place.

How to Froth Milk Like a Barista
Heat milk to 60 - 65 °C (140 - 150 °F). Do not boil - overheated milk will not froth well. Pour milk into a tall cup or the InstaCuppa glass frothing pitcher. Fill only to one-third capacity, as the foam will expand. Submerge the whisk head fully into the milk before turning it on.

- Submerge the whisk head fully into the milk before turning it on.
- Tilt the frother at a slight angle (about 15°) and move it slowly up and down.
- Froth for 15 - 20 seconds until you get a thick, creamy layer of microfoam.
- Turn off the frother while still submerged, then remove it.
Best milks for frothing: Full-fat dairy milk froths the best. Among plant-based options, oat milk and soy barista blends produce the creamiest foam.
How Do You Clean and Maintain It?
After every use: Dip the whisk into a cup of hot water and run it for 5 seconds. This removes 90% of milk residue. Weekly deep clean: Remove the whisk. Wipe the frother body with a damp cloth. Wash the whisk with dish soap and warm water.

Frequently Asked Questions
Can I use the milk frother for things other than milk?
Yes. The frother works great for mixing protein shakes, matcha lattes, hot chocolate, bulletproof coffee, and even salad dressings. Use the mixing whisk (flat disc) for non-frothing tasks.
How long does the rechargeable battery last before needing replacement?
The built-in lithium battery is rated for approximately 500 charge cycles, which translates to roughly 2 - 3 years of daily use. The battery is not user-replaceable, but after 500 cycles it will still hold about 70 - 80% of its original capacity.
Is the frother dishwasher safe?
No. The motor unit and handle must never be submerged in water or placed in a dishwasher. Only the detachable whisk can be washed with water. Wipe the handle with a damp cloth.
What type of batteries does the battery edition use?
The battery-operated model uses 2x standard AA batteries. Alkaline batteries are recommended for best performance. One set of quality batteries lasts approximately 100 - 150 uses.
Can I froth cold milk for iced lattes?
Yes. Cold milk froths well too, though the foam will be slightly less dense than with heated milk. For iced lattes, froth cold milk for 20 - 30 seconds, then pour over ice and espresso.
