Can You Put Tupperware In The Dishwasher? The Surprising Answer That Will Change The Way You Clean Your Kitchen!

The dishwasher, a modern marvel that simplifies our daily lives, has sparked a heated debate among kitchenware enthusiasts: can tupperware go in the dishwasher? The answer, like the contents of a well-sealed Tupperware container, is not always as straightforward as it seems.

Understanding Tupperware’s Components

Tupperware containers are typically made from a variety of materials, including:

• Polypropylene (PP): A durable and heat-resistant plastic
• Polyethylene (PE): A flexible and low-density plastic
• Polycarbonate (PC): A strong and clear plastic

Dishwasher Compatibility Guidelines

While some Tupperware containers are dishwasher-safe, others may not withstand the harsh conditions of a dishwasher cycle. To determine the dishwasher compatibility of a specific Tupperware container, consult the following guidelines:

• Check the Label: Look for the dishwasher symbol on the bottom of the container. If the symbol is present, the container is dishwasher-safe.
• Avoid Extreme Temperatures: Avoid placing Tupperware containers in the dishwasher’s heated drying cycle, as high temperatures can warp or damage the plastic.
• Use the Top Rack: Place Tupperware containers on the top rack of the dishwasher, where they will be exposed to less heat and water pressure.
• Avoid Overcrowding: Ensure there is sufficient space around the containers to prevent them from rubbing against each other and sustaining scratches.

Considerations for Different Materials

• Polypropylene (PP): Dishwasher-safe and can withstand temperatures up to 250°F (121°C).
• Polyethylene (PE): Dishwasher-safe, but may become deformed if exposed to high temperatures.
• Polycarbonate (PC): Dishwasher-safe, but should not be used for storing hot liquids or foods.

Exceptions to the Rule

Certain types of Tupperware containers are not dishwasher-safe, including:

• Vintage Tupperware: Older Tupperware containers may not be dishwasher-safe due to changes in manufacturing materials over time.
• Containers with Metal Components: Avoid placing containers with metal lids or handles in the dishwasher, as they can rust or cause damage to the dishwasher.
• Microwave-Only Containers: Containers labeled for microwave use only should not be placed in the dishwasher.

Alternative Cleaning Methods

If a Tupperware container is not dishwasher-safe, alternative cleaning methods can be employed:

• Hand-Washing: Use warm soapy water and a soft sponge to gently clean the container.
• Baking Soda: For stubborn stains, create a paste of baking soda and water and apply it to the affected area. Allow it to sit for a few minutes and then rinse thoroughly.
• Vinegar: Vinegar is a natural disinfectant. Fill the container with vinegar and let it sit for a few hours or overnight. Rinse thoroughly afterward.
