In the experience of Espresso Deco staff, to ensure the consistent quality of the product it is recommended to hand-wash the cup and saucer in warm water. Taking good care cleaning the product will help the product to stay in good condition for a longer period of time.
Espresso cups and saucers from Espresso Deco are made from high quality materials. The manufacturer's guidelines from the relevant Association of Commercial Dishwashing state that the products are dishwasher-friendly.
If detergent and rinse aid are dosed correctly, there is no difficulty in washing the products in a home or commercial dishwasher.
Even with decorated porcelain, there is still no issue with washing the products in a dishwasher as long as the total salt content of the water is not too high.
