The applicability of dishwasher capsules to tableware made of different materials varies. The following are some common application scenarios for tableware made of different materials:
Ceramic tableware: Ceramic tableware fired at high temperatures, such as high white porcelain, is hard in texture. As long as there are no complex carvings or paintings, it can usually be washed in a dishwasher. There is no problem with ceramic tableware with in-glaze and underglaze colors either. However, ceramic tableware with metal edges or decorations, such as gold-rimmed porcelain plates and silver-rimmed ceramic bowls, due to the different thermal expansion coefficients of metal and ceramic, the edges are prone to loosening and falling off during the dishwasher’s rinsing and drying process, and may also scratch the machine and affect the appearance. Therefore, they should be placed in with caution.
Glass tableware: Borosilicate glass tableware of qualified quality and high-temperature resistance can withstand the high temperature and water flow impact of the dishwasher. After cleaning, it is transparent and shiny. However, for carved glass, colored glazed glass bowls and handcrafted items of uneven thickness, high temperatures may cause the glaze to peel off or hidden cracks. It is recommended to hand wash them. Glass bowls with metal edges are also not suitable for machine washing, as the difference in expansion coefficients between metal and glass can easily lead to cracking.
Stainless steel tableware: 304 stainless steel tableware has excellent corrosion resistance and high-temperature resistance. Facing the high-pressure water spray and multi-angle flushing of the dishwasher, oil stains and residues can be easily removed. However, for stainless steel tableware with wooden or plastic handles, high-temperature water flow can cause the wood to crack, the plastic to deform or release harmful substances. Stainless steel tableware with coating or precious metal decoration. The coating is prone to scratches and peeling, and the precious metal decoration may fall off, affecting both usage and appearance. Such tableware is not suitable for being put in the dishwasher.
Plastic tableware: Plastic tableware marked with the words “dishwasher safe” is tough in material, wear-resistant and can be cleaned smoothly. High-temperature resistant plastic tableware, such as PP (polypropylene) plastic tableware, can also withstand the high temperatures of dishwashers. However, low-quality plastics can release harmful substances at high temperatures, and thin plastic containers are prone to deformation and damage under the impact of water flow. Such plastic tableware is not suitable for being put in the dishwasher.
Wooden tableware: Wood has a strong water absorption capacity. The humid and hot environment in the dishwasher will cause it to deform, crack and breed mold. Even if it dries, it will become fragile. Therefore, wooden plates, chopsticks and the like should not be put into the dishwasher.
Special coated tableware: Non-stick tableware with special coatings, such as Teflon-coated pans, may be scratched by a dishwasher during strong cleaning, affecting its non-stick performance. The peeling particles may also remain and be ingested, posing a threat to health. Therefore, it is not suitable to be put in a dishwasher.
