Step #2. Fill the container with white vinegar

Now that the container is empty, you can use white vinegar to kill the mold. Vinegar has antifungal properties because the acid content inhibits most fungal growth.

Fill your plastic food container with white vinegar, place the lid, and shut it tightly. For bigger plastic containers with non-food items, you can simply spray the vinegar onto the affected areas.

It would be best to let food containers sit overnight. You may also let it sit to make sure that the mold is thoroughly killed.

For other plastic containers, one hour may be enough.


Step #3. Wash the container

Once the container is ready, you can now dump out all the vinegar and begin cleaning. To clean out mold stains, all you have to do is wash with warm, soapy water.

For tough stains, you can use a brush with soft bristles to scrub the mold away. Make sure to wash thoroughly and dry the container using a clean piece of cloth.

If the container is clean, you can put it away. However, if there are still mold stains or the container still smells like mold, you can proceed to the next step.


Step #4. Use baking soda

If vinegar does not work, then you can try baking soda. While white vinegar is acidic, baking soda is basic.

This basicity means baking soda will expose the mold fungus to a harsh, alkaline environment where fungi cannot grow.

Simply put a tablespoon of baking soda into the plastic food container and spread it over the mold. Clamp the lid on shut and leave it overnight.

If you want to, you may also let it sit for a week. Once enough time passes, you can dump out all of the baking soda.

Like before, you will now be able to clean the area with warm, soapy water. It would help to use a brush for tough stains.

Once you are done washing, rinse and dry the container with a clean piece of cloth. You can now put it away safely or even begin using it again.
