3. Expensive Knives
Good knives are too expensive and destroying them would be such a pity! Clean your knives by hand. Dry them afterwards. Store them in a cool and dry place. Washing knives in the dishwasher might make the metal rust.
4. Nonstick Pans
Your wonderful nonstick pan will be ruined once placed in the dishwasher. Dishwashers are rather harsh machines and they can damage the coating of the pan. After washing a nonstick pan in the dishwasher you will never be able to prepare tasty pancakes and eggs using the utensil. Never put your pans in the dishwasher or buy a nonstick pan that can be safely washed in the machine.
