What Removes Stains from Tupperware?

I don’t always worry too much about the look of stains on my Tupperware. I find they will fade with use and frequent washing.

However, if things get too bad one of these methods will help you to remove unsightly stains.

Baking Soda

Make a thin paste with baking soda and water. Use this mixture to scrub the stain-affected areas, using an old toothbrush. Allow the mixture to soak in for around 30 minutes. Then rinse off the baking soda mixture.

Denture Tablets

Place two denture tablets in the plastic container add warm water and leave overnight. In the morning rinse and clean the container.


There are two schools of thought here. Some people say no way as the plastic will absorb the bleach and it won’t wash away. Also, if you are trying to run an eco-friendly home you won’t have bleach in your home because of the way it can damage the environment.

I have used bleach in the past it works well and doesn’t affect the plastic. Try a squirt of bleach in warm water, then leave for 1 – 8 hours before rinsing thoroughly. I have encountered a problem of getting rid of the bleach smell, but provided you rinsed the bleach away well it will disappear if you leave the Tupperware to air. So don’t stack until the smell disappears.

Not all Tupperware products are suitable for cleaning in a dishwasher. Often the base is dishwasher safe yet the lid is not. It is best to look at the label that is printed underneath each piece.

Generally, place dishwasher-safe pieces on the top rack. If you encounter a problem with containers flipping over by the force of the waterjets during washing. Place a metal cooling rack over the containers.
