Setup
- Unpack: Carefully remove the Tefal Masterseal Ice Cube Tray from its packaging.
- Initial Cleaning: Before first use, wash the tray and lid thoroughly with warm soapy water or place them in a dishwasher. Rinse well and dry completely.
- Inspect: Check the tray and lid for any signs of damage. Do not use if damaged.
Operating Instructions
- Filling the Tray: Place the tray on a flat, stable surface. Carefully fill each compartment with water or your desired liquid (e.g., juice, broth, pureed baby food). Avoid overfilling to prevent spillage when the lid is applied.
- Securing the Lid: Place the lid onto the tray, ensuring it aligns correctly. Press down firmly on all four sides until the clips engage, creating a watertight seal. This prevents spills and freezer odors from affecting the contents.
- Freezing: Place the sealed tray flat in your freezer. Allow sufficient time for the contents to freeze completely.
- Removing Ice Cubes: Once frozen, remove the tray from the freezer. To release ice cubes, simply twist the tray slightly or press on the flexible silicone base of each individual compartment from the underside. The flexible design allows for easy release of single cubes.
- Storage: Store any unused ice cubes or frozen portions in a freezer-safe container. The Masterseal tray can be refilled and frozen again.
Maintenance and Care
- Dishwasher Safe: The Tefal Masterseal Ice Cube Tray and lid are fully dishwasher safe. Place them on the top rack for best results.
- Hand Washing: If washing by hand, use warm water and a mild dish soap. Use a soft sponge or cloth to clean all surfaces. Rinse thoroughly to remove all soap residue.
- Drying: Ensure the tray and lid are completely dry before storing to prevent water spots or bacterial growth.
- Hygiene: Thanks to its patented freshness seal, the tray is designed to prevent germ accumulation. Regular cleaning as described above will maintain its hygienic properties.
- Storage: Store the tray and lid in a clean, dry place when not in use. The stackable design allows for efficient storage.
- Avoid Abrasives: Do not use abrasive cleaners, scouring pads, or sharp objects, as these can scratch or damage the plastic.
Troubleshooting
- Ice Cubes Sticking: If ice cubes are difficult to remove, try twisting the tray gently or running the underside of the tray under warm water for a few seconds before pressing the flexible bases.
- Lid Not Sealing Properly: Ensure the lid is correctly aligned with the tray and that no ice or debris is obstructing the seal. Press firmly on all four clips until they click into place.
- Unpleasant Odors: If the tray develops an odor, it may be due to strong-smelling foods in the freezer or insufficient cleaning. Wash the tray thoroughly with warm soapy water, or run it through a dishwasher cycle. For persistent odors, a solution of baking soda and water can be used for soaking.
- Tray Warping: Avoid exposing the tray to extreme heat sources (other than microwave use as specified) or placing it in a hot oven, as this can cause warping.
