Setup, Compatibility & Care
To ensure your Heftman bottles last, follow these usage guidelines:
- Pre-Wash: Before the first use, clean the bottles and lids with warm soapy water using the provided brush.
- Temperature Limits: Ensure your liquids are between 0-70℃. Never pour boiling water directly into the bottle, as the thermal shock may crack the glass.
- Manual Cleaning Only: These bottles are not dishwasher safe. Always hand-wash to protect the structural integrity of the glass and the silicone O-rings.
- Storage Precautions: Do not place these bottles in the freezer, as the liquid expansion will cause the glass to shatter.
- Seal Maintenance: Periodically inspect the silicone O-ring inside the lid to ensure it remains seated correctly for a leak-proof seal.
