To use this method, make a diluted bleach solution with one part bleach and one to two parts water. Fill your plastic container with the solution and let it soak for about half an hour. After itâs done soaking in the solution, give the container a good scrubbing with hot water and dish soap.
I use baking soda and Dawn dish liquid. Add hot water, let them soak for a little while, then rinse and they are looking new. don't use bleach. I would never use bleach to remove stains from plastic because it breaks the plastic it down and it's poison if not washed out thoroughly. Try using a baking soda and vinegar paste, then wash normally in warm water.
