Why
Many plastic lunch boxes are top-rack dishwasher safe, but prolonged high heat can warp or degrade them. Stainless steel or glass lunch boxes are generally dishwasher safe, but those with plastic lids or silicone seals may require hand washing to preserve the seal. Always check the manufacturer's label.
How do you wash Lunch Box?
Place plastic lunch boxes on the top rack away from heating elements. For containers with gaskets or intricate lids, hand wash with mild soap and warm water to extend lifespan.
