After using lunch boxes for a long time, it is inevitable that various food residues will produce odors, especially after they have been used to hold food with strong odors. Today, I will share 5 simple and practical methods to help you easily remove stubborn odors from lunch boxes.
1. Soaking in baking soda water
Dissolve a spoonful of baking soda in warm water, soak the lunch box for 2-3 hours, and then rinse it with clean water.
2. Deodorizing with white vinegar
White vinegar can not only kill bacteria, but also neutralize odors. Mix white vinegar and water in a 1:1 ratio, pour it into the lunch box and let it stand for 30 minutes, then pour it out and rinse it with clean water.
3. Tea adsorption method
Don't rush to throw away the soaked tea leaves. Put the wet tea leaves in the lunch box, cover it with a lid and leave it overnight.
4. Sun exposure method
When the weather is good, open the lid of the cleaned lunch box and place it in the sun for 2-3 hours. Ultraviolet rays have a sterilizing effect, and sunlight can also help volatilize residual odor molecules.
5. Deodorizing with coffee grounds
Put the dried coffee grounds into a small gauze bag and seal it in a lunch box for 24 hours. The coffee grounds can absorb the complex smells of various foods.
Daily tips: Clean the lunch box in time after each use to avoid long-term retention of food residues and odor. Plastic lunch boxes are more likely to absorb odors.
The above methods can be used alone or in combination according to the actual situation. In most cases, they can effectively solve the odor problem of lunch boxes.
