The best way to avoid this: make a habit to remove everything from your lunch bag right away. Then use a slightly damp towel with a small amount of mild dishwashing detergent, wipe the inside and outside, and allow to air dry.
We like to alternately use an antibacterial wipe to wipe clean both the inside and outside of our lunch bag, and don't forget the handles. If you do this daily after using your Stöh Lunch tote, you'll never have to worry about a smelly lunch bag.
However, just in case, Friday's tuna fish sandwich with extra mayonnaise is still in your unrefrigerated and forgotten lunch bag, and well, it's now Monday morning, you're probably going to want to try this easy fix:
Take a slice of bread or a paper towel and moisten until it's completely damp but not dripping with white household vinegar (preferably distilled). Place it in your lunch bag, close the bag and leave overnight. In the morning, remove and discard the paper towel or slice of bread and wipe the inside of the lunch bag with a clean, damp towel and allow to air dry.
Sprinkle baking soda inside the lunch bag and stuff with crumpled newspaper to absorb the moisture and smell. Close the bag and after 1 or 2 days, remove and discard the newspaper and baking soda. Wipe the inside of the lunch bag with a clean, damp towel and allow to air dry.
Sounds so simple, right?! Feel free to comment below to let us know which option works best for you.
