Dishwashers that use metal racks or have worn-out plastic coatings on their racks can potentially leave scratches on dishes. The scratches are usually caused by the friction between the dishes and the dishwasher's racks during the washing and drying cycles. Here are two common scenarios where scratches may occur:
Metal Racks: Some dishwashers have racks made of metal wires coated with vinyl or other protective materials to prevent scratching. Over time, the protective coating on these racks can wear off or get damaged, exposing the bare metal. When dishes come into contact with the metal surface during the wash cycle, they can get scratched.
Worn Plastic Coating: In some dishwashers, the racks are made of plastic with a coating to protect the dishes. However, with repeated use and exposure to heat and detergents, this coating can wear off or develop rough spots. When dishes rest against these rough spots during the wash cycle, scratches may occur.
To reduce the likelihood of scratches on dishes in a dishwasher, you can take the following measures:
- Inspect the dishwasher racks regularly and replace them if you notice any signs of wear or damage to the protective coating.
- Use dishwasher-safe and scratch-resistant dishes. Avoid placing delicate items or those with delicate finishes directly against the dishwasher racks.
- Load the dishwasher carefully, ensuring that dishes are securely placed in their designated areas to avoid unnecessary movement during the wash cycle.
- If you notice scratches on your dishes, consider handwashing those specific items to minimize further damage.
Additionally, using a quality dishwasher detergent designed to be gentle on dishes can help prevent abrasive particles from causing scratches during the wash cycle. If you are concerned about potential scratching, you may also consider using the dishwasher's gentle or delicate cycle for more fragile items.
