When someone in the house has a food allergy or intolerance, storage stops being a small detail. Cross-contact and lingering residues matter. Stainless steel helps in a way plastic can’t.
It doesn’t hold residue in scratches. Worn plastic develops fine scratches that trap food particles, oils, and smells — exactly where an allergen can linger after washing. Steel’s hard, non-porous surface doesn’t harbor residue the same way, so a proper wash gets it genuinely clean. It doesn’t clean itself, though — the wash still has to happen.
It has no coating to break down. Food-grade 304 steel is bare metal: no lining, no lacquer, no colour layer that can wear through into the food. That’s a smaller claim than “inert,” and it’s the one we can actually make — steel isn’t inert, and we’ve never said otherwise. What it is, is knowable: 304 stainless steel and one food-grade silicone seal, and nothing else.
It cleans completely. No stain, no smell carried from one food to the next — helpful when you’re keeping, say, gluten-containing and gluten-free foods reliably separate.
A practical system: dedicate specific containers to specific needs. Because steel is so durable, a set can be assigned to an allergen-free routine and stay that way for years. Ours all look the same — we don’t make coloured lids — so if you need them unmistakable, a strip of tape and a pen does the job.
Don’t forget the seal. Remove and wash the silicone gasket separately — it’s the spot most likely to hold residue if ignored. It’s also the part that wears out, so we sell it separately.
None of this is a medical claim, and steel doesn’t treat an allergy — always follow the guidance you’ve been given for the specific one. But as a storage material, steel removes several of the small doubts that plastic quietly introduces.
Food should be stored without doubt.
