How to remove mold on the sealing ring of the lunch box

The mold on the sealing ring of the lunch box can be removed with white vinegar, baking soda, bleach, alcohol, or specialized cleaning agents. Mold spots are mainly caused by factors such as food residue, humid environment, incomplete cleaning, adhesion of sealing ring materials, and long-term storage. The appropriate method should be selected according to the degree of mold spots.

1. White vinegar

The acetic acid in white vinegar can effectively decompose mold. Mix white vinegar and water in a 1:1 ratio, dip a soft cloth in it, wipe the mold on the sealing ring, let it stand for 10 minutes, and then rinse. White vinegar is non corrosive to silicone material and suitable for slight mold stains. After wiping, it should be thoroughly dried to avoid residual acidity.

2. Baking soda

Baking soda has adsorption and weak alkaline cleaning effects. Take a small amount of baking soda and add water to make a paste. Use a toothbrush to gently brush the moldy area. Stubborn stains can prolong the standing time. This method is suitable for rubber sealing rings, and after cleaning, they need to be repeatedly rinsed with clean water to prevent particle residue.

3. Bleach

Diluted bleach can kill deep-seated mold. Mix 5% bleach with warm water, soak the sealing ring for no more than 5 minutes, and use cotton swabs to assist in cleaning key areas. Bleach is suitable for PP material sealing rings, and it should be thoroughly rinsed after use to avoid chemical residues.

4. Alcohol

75% medical alcohol can quickly kill surface mold. Spray alcohol directly and cover the moldy area with kitchen paper. Wipe it off after 5 minutes. Alcohol evaporates quickly and leaves no residue, making it suitable for emergency cleaning, but its effect on stubborn mold spots is limited and requires physical wiping.

5. Special cleaning agent

Food grade sealing ring cleaning agent contains active oxygen components, which can penetrate gaps and decompose mold spots. Spray according to the instructions and let it stand. Stains can be decomposed without scrubbing. This type of cleaning agent has good compatibility with various materials, but the cost is relatively high. It is recommended for severe mold stains or frequent cleaning needs.

After daily use of lunch boxes, the sealing ring should be disassembled and cleaned separately, with a focus on cleaning the food grease in the grooves. Thoroughly clean at least once a week, then place in a well ventilated area to dry thoroughly. Regularly rinse and disinfect with boiling water. Avoid scratching with hard objects such as steel wire balls, and ensure that the inside and outside of the lunch box are dry during storage. If mold has penetrated the interior of the material or cracked, it is recommended to replace the sealing ring with a new one to ensure food safety.
