Check the manufacturer’s instructions before putting an item in the dishwasher. Unfortunately, not all items have this information on their labels.
As a rule, avoid putting utensils that have stick-on parts, hand-painted dishes or porcelain items with gold or silver details in the dishwasher. Also, aluminium or aluminium-coated pots and pans can cause corrosion in your glassware.
Here is a list of common kitchenware that you should avoid washing in the dishwasher:
- Cast iron
- Hand-blown and hand-painted glass
- Wooden utensils
- Non-stick pans
- Copper pans
- Soft plastic
- Aluminium utensils
- Disposable aluminium
- Gold-plated dishes
- Insulated mugs
- Anything with adhesives
- China (hand-painted or antique)
- Hand-painted ceramics/stoneware
