This page is deliberately narrow: it covers what storage bag/container you'd shop for and what cleaning supplies pump parts commonly need — not medical guidance about milk safety.For current, authoritative storage-duration and cleaning guidance, check your pump/bag manufacturer's own instructions and your pediatrician, not this page.

This table reflects commonly published storage-duration guidance (compiled 2026-07-22, no single health-authority citation independently re-verified this session — treat it as a starting reference, not a guarantee). Always check your own storage bag/container's printed instructions and your pediatrician for anything you're relying on for your baby's health. This is a shopping-logistics reference (how long a storage bag needs to hold up), not a medical claim from this site.
Most pump manufacturers recommend hand-washing removable parts with a dedicated bottle brush and a pump-part-safe soap, then air-drying, with occasional steam-sanitizing (a microwave steam bag or a dedicated sanitizer) for a deeper clean. Follow your specific pump's manual for its actual recommended routine and frequency — this page only covers what supplies you'd shop for, not a step-by-step cleaning protocol.
