Why is a household dishwasher allowed, but a commercial one should not be used?

Use in a household dishwasher is permitted, but it cannot be placed in a commercial dishwasher^[1][2][3]. Generally, commercial dishwashers use high-pressure water streams and high-temperature rinse water for rapid washing. During this process, if the glassware undergoes sudden temperature changes or is pushed by strong water streams and collides with other tableware, the risk of cracking or breaking increases. On the other hand, household machines have relatively gentle water pressure and smaller temperature variations, resulting in less impact on the glass.

When using a dishwasher at home, it is safe to space the glasses so they do not touch each other and place them upright on a dedicated rack. Even glassware with distinctive shapes, such as the Tebineri mini carafe or beer glass, can be conveniently washed and maintained at home without the hassle of handwashing^[4][5].
