6 Steps To Getting Rid Of Mold In Plastic

Step #2. Wash away the visible mold

With a detergent or dish soap that is ammonia-free, wash away all the mold you can see. It is essential that you check for ammonia content because you will be using bleach later on. Bleach and ammonia when mixed will create toxic fumes which are harmful when inhaled.


Step #3. Create a bleach solution

For the cleaning solution, mix ½ cup of bleach and a gallon of water. For severe cases of mold, mix a stronger solution by adding another ½ cup of bleach.


Step #4. Soak the plastic container in the solution

Pour the solution in a pail or basin and soak in the plastic container or bottle. Make sure that all the moldy parts are fully submerged. Allow it to sit for no less than 15 minutes.


Step #5.  Scrub off the remaining mold and rinse

After soaking, scrub the remaining mold from the plastic container using a sponge or soft cloth and ammonia-free detergent or dish soap. Then, thoroughly rinse the container to wash away the bleach and soap.


Step #6. Dry the plastic container

One washed, put the container in a draining pan upside down, to let the water drip down. Wait for it to dry completely before using.
