Leftover spaghetti sauce stores well in airtight plastic containers for later use. While tomatoes add to the flavor and eye appeal, the lycopene found in them causes a red or orange stain on plastic. You don't have to toss your plastic bowls or live with discolored containers, however. You can get rid of spaghetti sauce stains on your plastic bowls with supplies commonly found in the kitchen.
Rinse out the plastic bowl with water. Dry it with a towel. Set the bowl in a sunny window or outside in the sun for two to three hours so the sun can bleach the stain.
