Plastic food containers love to hold onto grease and color. Tomato sauces, curries, and oily leftovers are the usual culprits.
Supplies
- Dish soap
- Baking soda
- Warm water
- Soft sponge
Method
- Wash with hot soapy water first.
- Sprinkle baking soda inside the container.
- Add a few drops of water to make a paste.
- Rub gently with a soft sponge.
- Rinse well.
If the stain remains
A short period in bright sunlight can help fade discoloration after washing.
Granny’s bottom line
Plastic stains are easier to improve than to erase completely. The goal is clean and usable, not showroom perfect.
