5.2 Cleaning Before First Use
It is recommended to clean the whisk head before using the frother for the first time. Refer to the 'Maintenance and Cleaning' section for detailed instructions.
6. Operating Instructions
The CIRCLE JOY Milk Frother is designed for simple, one-touch operation.
- Pour your desired liquid (milk, coffee, etc.) into a cup or container. For best frothing results, ensure the liquid level allows space for foam expansion.
- Remove the protective storage tube from the frother.
- Immerse the stainless steel whisk head into the liquid. Ensure the whisk is fully submerged but not touching the bottom or sides of the container to avoid splashing.
- Press the One Touch Button located at the top of the frother to start the whisking action. The frother operates at approximately 13,000 rotations per minute.
- Move the frother gently up and down in the liquid for about 15-20 seconds, or until the desired foam consistency is achieved.
- Press the One Touch Button again to turn off the frother.
- Carefully remove the frother from the frothed liquid.

Tips for Best Results:
- For milk frothing, cold milk (especially whole milk) generally produces the best and most stable foam.
- Heat milk to approximately 150-160°F (65-70°C) before frothing for hot beverages.
- Do not overfill your cup to prevent spills.
