– The easiest way to remove odor from plastic containers is to use dishwashing liquid with a strong scent to clean the entire inside of the container. However, there are cases where the odor is too persistent and dishwashing liquid cannot solve the problem. In this case, you need to use a pure water solution to pour into the plastic container and soak for about two hours. Use the water solution to clean the lid of the container as well. Then, rinse both the container and the lid with clean water, dry them and continue to smell to check if they still have a bad smell. Usually, this method will help eliminate any “stubborn” odor.
