Baking soda is an incredibly effective and natural cleaning agent. Its mild abrasiveness helps scrub away stains without scratching the surface of the plastic, while its alkaline properties help break down oils and pigments that can cause stubborn discoloration. When combined with the sun’s natural UV rays, the cleaning power is further enhanced.
Sunlight also helps neutralize odors that may linger in your Tupperware, leaving it smelling fresh.
1. **Avoid Storing Hot Foods**: Whenever possible, let your food cool down before placing it in Tupperware containers. Hot food can cause plastic to absorb stains more easily.
2. **Choose Lighter-Colored Tupperware**: If you find yourself constantly battling stains, you might want to opt for lighter-colored plastic containers. Darker plastics tend to show stains more readily, so going for clear or light-colored Tupperware could save you some trouble.
4. **Try a Baking Soda Soak for Really Stubborn Stains**: For tough stains that won’t budge with the paste method, fill your Tupperware with warm water and add a couple of tablespoons of baking soda. Let the container soak for a few hours (or overnight) before scrubbing and rinsing.
My Nana’s trick for removing stubborn Tupperware stains is simple, natural, and incredibly effective. By combining the power of baking soda and a little sunshine, you can keep your plastic containers looking brand new for years. So, the next time you find yourself battling stains in your Tupperware, just remember: **a little patience and some baking soda go a long way**.
