Maintenance and Care
Proper care will extend the life and maintain the appearance of your Tupperware containers.
- Dishwasher Use: All components are dishwasher safe. For best results and to prevent warping, place containers on the top rack of the dishwasher.
- Hand Washing: If hand washing, use a soft sponge or cloth with warm, soapy water. Avoid abrasive cleaners or scouring pads that could scratch the plastic.
- Stain Removal: For stubborn food stains (e.g., tomato sauce), create a paste of baking soda and water, apply to the stain, let sit for a few hours, then wash. Sunlight can also help reduce stains.
- Odor Removal: To remove odors, wash thoroughly and air dry with lids off. A crumpled piece of newspaper or a cotton ball soaked in vanilla extract placed inside the container for a day can also help absorb odors.
- Microwave Use: Containers are microwaveable. When microwaving, always vent the lid or remove it entirely to prevent pressure buildup and potential damage. Do not use for cooking, only reheating.
- Freezer Use: Containers are suitable for freezer storage. Allow hot foods to cool before placing them in the freezer to prevent condensation and potential damage to the container.
- Storage: When not in use, store containers with lids slightly ajar or separately to allow air circulation and prevent odors. The stackable design allows for compact storage.

Troubleshooting
Here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lid difficult to seal | Lid or container not aligned; food overfilled; lid or container warped. | Ensure proper alignment. Do not overfill. Check for warping; if warped, contact support. |
| Lid difficult to open | Strong vacuum seal; cold temperature. | Use the easy-open tab. Allow container to warm slightly if taken directly from freezer/refrigerator. |
| Staining on container | Contact with highly pigmented foods (e.g., tomato sauce, curry). | Clean immediately after use. Apply baking soda paste or expose to sunlight. |
| Lingering odors | Strong-smelling foods stored for extended periods. | Wash thoroughly and air dry. Use baking soda or vanilla extract method. |
