|---|---|---|
| Hygiene & Ease of Cleaning | 9.0RTINGS cleaning 9.5 (snippet) corroborates Carepod's three-part, boilable stainless design. Trimmed to 9.0 because the full review is paywalled. | 6.0Babylist's 'easy to clean' pro plus cleaning alerts. No dishwasher-safe parts confirmed and not lab-tested. |
