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.
