Caring for your Porcelain Porcelain in the dishwasher Porcelain is exposed to many influences in the dishwasher. The composition of the detergent, the temperature of the machine, the degree of water hardness and the method of drying. All this determines the durability of the items. It is important to follow the guidelines issued by the manufacturer eg, to regularly refill the salt storage container and to follow the dosage recommendations for detergents. Dishwashers that do not automatically disperse the heat should be opened immediately after the rinsing cycle is finished. The porcelain must be placed in such a way that it does not touch or rub. For dishwasher use, we divide the patterns into three groups. We make a distinction between precious, dishwasher suitable and dishwasher safe patterns as follows: Precious decoration The appearance of the decoration - the art design - is the predominant feature of the porcelain. Dishwasher suitability is not the first consideration and we recommend that such ware must always be washed by hand.
