Look at the whole assembly

A listing may mention stainless steel without describing the exterior shell, adhesives or handle. Record which parts touch the drink and which are decorative. A claim about the insert alone does not establish that every part can tolerate the same cleaning method.

Make a care note

  • Exact model and variant.
  • Intended drinks and temperature guidance.
  • Dishwasher and microwave: allowed, prohibited or not stated.
  • Permitted cleaning products and drying instructions.
  • Where to find replacement or maintenance guidance.

Do not fill gaps with assumptions

A coffee photograph is not documentation of drink-contact suitability. If the interior cracks, the surface changes or a part loosens, stop using it and contact the manufacturer. This guide provides a checking method rather than a home test that certifies safety.

Sources and method

Decalavera’s editorial criteria and examples use AI assistance and documentary checking. References support their specific cultural or technical context; they do not certify products or represent physical tests. Sources from other jurisdictions are not presented as US product certification.
