How to Clean Plastic Lunch Boxes


Plastic lunch boxes keep your food and drink items safe, and prevent waste caused by brown paper bags. Cleaning the lunch box prevents bacteria and germs from building up on the inside and outside, and also lifts any leftover food and drink stains. A homemade plastic cleaner removes the bacteria and stains without staining or damaging the lunch box. This cleaner also eliminates foul odors that appear inside the lunch box because of food and drink items.

Things You'll Need

  • Water
  • Sink
  • Drain stopper
  • White vinegar
  • Baking soda
  • Non-bleach liquid dish soap
  • Sponge/cloth/dish scrubber
  • Towel (optional)
  • Empty all items from the lunch box.

  • Rinse the inside and outside of the lunch box.

  • Place the open lunch box inside of a clean sink and plug the sink's drain with a stopper.

  • Pour about 1 cup of white vinegar, ¼ cup baking soda and ¼ dish soap inside the sink, and then fill the sink with hot water.

  • Soak the plastic lunch box for 15 to 30 minutes and then scrub the box thoroughly with a sponge, cloth or dish scrubber.

  • Dry the lunch box thoroughly or allow it to fully air dry. Make sure the box is completely dry before putting it away or adding items into the box.
