Using these large plates is a breeze. Just put your food on them and enjoy your meal. When you're done, you can either wash them by hand with some mild dish soap or simply toss them in the dishwasher - they're dishwasher safe. As for maintenance, make sure to avoid using abrasive cleaners as they could scratch the surface. Also, don't expose the plates to extremely high temperatures outside of normal dishwasher use. With proper care, these plates will serve you well for a long time.
