One of the best things to do is to open the lunch box when you get home and take out containers. According to StateFoodSafety, it’s important to remove any plastic wrap, food storage containers, or perishable food as soon as possible to avoid bacteria from growing. This will help reduce the need for more intense cleaning and keep your lunch pail a safe place for your delicious lunch.
It’s a good idea to let the containers soak in hot, soapy water to help remove any stuck-on food gunk and if possible, it’s ideal to rinse them soon after using to minimize stains and food build-up (via Kitchn).
Wiping down the inside of your pail, bag, or box with a soapy sponge is also a good idea to help remove any bacteria and keep it clean (via StateFoodSafety). Then let it air dry and it will be ready to use the next day. Now, you know just what to do to ensure your lunch is in a clean environment and your lunch box will last a long time.
