But there’s a catch: your dishwasher isn’t as gentle as it looks. It’s more like a high-pressure chemical bath at high temperature. Ideal for plates. Not very suitable for anything else.

So let’s talk about the usual suspects – and a few surprises – before your dishwasher teaches you a painful lesson.

The obvious “don’t even think about it” items:
wooden kitchen utensils and cutting boards.
Wood and dishwashers simply don’t mix.
