Dishwasher-safe plastic lunchboxes, bento boxes and insulated lunchboxes are a modern marvel, taking a beating while protecting what you've packed. But whether you're a fan of the classic metal lunchbox or more modern types, spilled drinks and accumulated food grime will result in sticky, smelly messes that require attentive cleaning and deodorizing.
Cleaning by hand
- Fill the sink with warm water and ¼ cup of Simple Green All-Purpose Cleaner.
- Moisten a sponge or soft cloth with the cleaning mixture and wipe the interior and exterior of the lunchbox. If the lunchbox can be submerged in water, place it in the water and scrub entirely, focusing on problem areas.
- For heavier grime buildup, use an old toothbrush or soft bristle brush to remove gunk & grime.
- Rinse with clean water and dry with a towel or paper towel. If the lunchbox is insulated, make sure insulation is completely dry before reusing.
Cleaning Lunchbox in a Washing Machine (fabric or insulated lunchboxes)
While most insulated and fabric lunchboxes can be put in the washing machine, some won’t hold up under the agitation of a washer.
- Set your washer to the smallest load size on cold water, gentle cycle.
- Add ¼ cup of Simple Green to water-filled washer.
- After wash cycle is done, air dry the lunch box (do not put in dryer).
