They are made of the same enamel material; can both storage containers and pots be put in the dishwasher?

Even for NODA HORO enamel products, whether a dishwasher can be used differs depending on usage and composition.

Containers can, pots cannot. For White Series round containers, only the main body that comes into contact with food can be put into a dishwasher and cleaned^[1]. On the other hand, the lid used together with it is vulnerable to heat and cannot be placed in a dishwasher, let alone an oven or direct flame heating, so it must be hand-washed separately^[2].

Cookware from the LUKE line does not support dishwashers. For both the 21cm two-handled pot and the 18cm saucepan, microwave and dishwasher use are prohibited^[3][4]. For the 18cm saucepan, cooking inside an oven must also be avoided^[5].

Generally, enamel tableware has a structure in which vitreous glaze is baked on, so when exposed to strong water pressure from a dishwasher or specialized detergents, the surface gloss easily turns dull or the edge finish is easily damaged. Even for container main bodies where dishwasher use is permitted, they should be spaced apart so the coating does not crack from bumping into other tableware, and for pots, it is safer to wipe them down with a soft sponge soaked in lukewarm water.
