A lunch container is made from a lightweight aluminum alloy because it conducts heat well and is easy to clean. Students report a metallic taste when storing tomato-based pasta (acidic) for several hours. In a simple test, the container shows dull spots after soaking in tomato sauce overnight, while a stainless-steel container shows no visible change under the same conditions. Which refinement best addresses the evidence-based problem while keeping the container reusable?
