You should consider throwing away Tupperware if it shows signs of significant wear, such as cracks, stains, or a warped shape that prevents it from sealing properly. Additionally, if it has absorbed strong odors or stains that won't come out after thorough cleaning, it's time to replace it. Finally, if the container is made from older plastic that may contain harmful chemicals, such as BPA, it's advisable to discard it for safety reasons.
