Dishwasher suitable Bone China\nThe surface of Bone China is, in a technical sense, a type of glass and should be treated accordingly.\nPlease note the following:\nShould any film or coating appear, this is usually due to starch deposits which are not always properly removed in the dishwasher. Over time, such deposits can accumulate to form a relatively thin, but extremely resistant, layer which is also encouraged, for example, by:\n\n∙ heavily soiled dishes\n∙ hard tap water\n∙ wrong dosage of detergent\n\nIn general terms, it can be said:\nDeposits on glasses and porcelain glazes can only be avoided by an optimal use of water, water softeners, and a cleansing and rinsing agent.\nIn most cases, these deposits can be removed with a liquid porcelain cleaner, or a ceramic-glass cleaner for ceramic hobs. The glaze will usually remain undamaged. If the film has already formed a very strong bond with the surface, removal can be very difficult, or even impossible in some cases.\nAs regards dishwasher safety for hard porcelain and bone china, the statement: 'the harder and the less porous the material, the higher the dishwasher resistance', is essentially valid.\nMicrowave safe\nThis item can safely be used in the microwave.
