Your lunch box doesn't have to smell like yesterday's curry

Strong-smelling foods like fish and curry only linger if you let them sit and soak in.

The real trick is to wash the box as soon as you finish eating. The longer that oily, spicy residue sits, the deeper it gets into plastic scratches and seams. If you’re at work, give it a quick rinse with hot water and a drop of dish soap right after lunch. Even a wipe with a paper towel beats letting it bake in there all afternoon.

If it’s already smelling, don’t reach for bleach. A paste of baking soda and water left in the box for an hour kills most odors. Vinegar works too, but you’ll be trading one smell for another temporarily. And don’t underestimate sunlight — a few hours in the sun genuinely neutralizes some stubborn smells.

The nuclear option is to stop using porous plastic altogether. Glass or stainless steel containers don’t hold onto odors the way plastic does. If you’re attached to your current box, line it with parchment paper or a silicone bag for the stinky stuff. That way the container never touches the curry in the first place.

Wash fast, dry completely, and don’t let the stubborn stuff touch bare plastic. Future you will appreciate it.
