What is Dishwasher safe?

Dishwasher safe means a brand states that its main range of kitchenware can go through a dishwasher without damage. It saves washing up, but it can rule out items with a non-stick coating, a sealed wooden handle or a hand-applied glaze, and hand washing often extends their life. It is worth checking individual pieces rather than the whole range, since a brand can mix materials. BOLDE Bottle, Butlers.cz and Casafina say yes, while Challenger Breadware and Drinkmate say no.
