Things You'll Need
Create a cleaning paste by adding baking soda and lemon essential oil to a small bowl. Slowly add water while stirring to make a thick paste. The lemon essential oil helps pull the tomato stain away from the plastic while the baking soda helps work it in and scrub the stains away.
Work the paste into the stained plastic container and let sit for 10-15 minutes, then scrub with your sponge.
