Things You'll Need:
- Dish soap
- Baking soda
- Bleach
-
Step 1
Wash the container first with cold water, then with hot soapy water. For a minor stain, this may remove the red tint completely.
-
Step 2
Make a thick paste of baking soda and water. Rub this on the stain and let dry. Rinse off the baking soda mixture and wash the plastic container as usual.
-
Step 3
Remove stubborn stains by setting the plastic out in the sun for several hours. The natural bleaching effects of the sun can help get rid of the tomato sauce stain. Do not leave the plastic outside for too long, however, as it may become brittle.
-
Step 4
Soak plastic containers that still have tomato stains in a sink or bucket of bleach diluted in water.
