Operating Instructions
Once the lid is securely installed, you can use your milk frother as usual. The transparent design of the lid offers a practical advantage:
- Temperature Maintenance: The secure silicone seal helps maintain the milk's temperature during the frothing process, ensuring optimal results.
- Leak Prevention: The airtight barrier created by the seal prevents any milk leakage, keeping your countertop clean.
- Monitoring: The transparency allows you to visually monitor the frothing process inside the jug without removing the lid, ensuring your milk reaches the desired consistency.

Maintenance and Cleaning
Regular cleaning of your lid and seal is crucial for hygiene and to ensure continued optimal performance. The lid is designed for easy cleaning:
- After each use, allow the frother and lid to cool down.
- Remove the lid from the frother.
- Carefully remove the silicone seal from the lid for separate cleaning.
- Wash both the plastic lid and the silicone seal with warm, soapy water. Use a soft sponge or cloth to avoid scratching.
- Rinse thoroughly under running water to remove all soap residue.
- Allow both parts to air dry completely before reassembling and storing, or wipe dry with a clean cloth.
The premium plastic material is durable and resistant to heat and chemicals, ensuring it won't warp or melt over time, even with regular cleaning.
Troubleshooting
If you encounter any issues with your replacement lid, consider the following:
- Lid not fitting securely: Ensure the silicone seal is correctly seated in its groove. If the seal is twisted or misplaced, it can prevent a tight fit.
- Leakage during frothing: This often indicates an improperly seated silicone seal or a damaged seal. Re-seat the seal carefully, ensuring it forms an airtight barrier. If the seal is damaged, it may need to be replaced.
- Cloudiness or discoloration: While the lid is made from durable plastic, prolonged exposure to harsh chemicals or abrasive cleaning tools can cause damage. Use only mild soap and soft cloths for cleaning.
