### Tips for Using Tupperware Safely

* **Check symbols before microwaving:** Not all containers labeled microwave-safe can handle high heat—avoid heating fatty or sugary foods for long periods.
* **Avoid harsh scrubbing:** Even dishwasher-safe containers can warp or discolor if exposed to very high heat or abrasive cleaning.
* **Store appropriately:** Use freezer-safe containers for frozen foods to prevent cracking.
* **Replace old containers:** If plastic is cracked, discolored, or smells, it’s time to replace it for safety.
