Clearly, as was mentioned earlier, the construction of the jar or pitcher is critical. However, no matter how expertly it is designed you still need to do everything in your power to treat it with the utmost care. Besides ensuring it does not drop from a substantial height, you can also follow a few tips and tricks that should pay dividends for you in the long run. Many people will do this but you should avoid using your jar as a storage container. Do not allow liquids to rest in it overnight and transfer the remains into a separate container. Also, be sure you clean it thoroughly after each use.
But, you can also monitor the jar throughout its lifespan. Inspect the container and see if you see any signs of wear or cracking. You can also reference the care instructions of a specific machine to ensure you are doing everything right.
