Put plasticware with tomato sauce in a dishwasher and what do you get? Clean plasticware with tomato sauce stains. Here’s how to clean tomato sauce stains from your favorite plastic container in four easy steps.
Step 1: Hand Wash.
Using a concentrated dish liquid like Dawn®, wash the stained plasticware with a sponge, just as you would with any dish.
Step 2: Air Dry.
Place the plasticware on the drying rack and allow it to air dry.
Step 3: Place On The Windowsill.
After the plasticware has dried, move the container to a windowsill that gets direct light from the sun. Over time, the sunlight will bleach out the stain.
Step 4: Wait For The Magic To Happen.
Check back periodically. It may take several hours or even days to completely remove the stain. The waiting is the hardest part.
