What are the causes of discoloration?
If you find rust stains on your Corelle dishes, the cause is typically the dishwasher. The racks in most dishwashers are made of metal and coated with vinyl to protect them from rust.
In the long run, this vinyl coating will start to chip and peel away. Once this occurs, the dishwasher racks will start to rust, possibly transferring to your dishes. As a result, you might find small, but obvious, rust spots on the edges or rims of your dishes. If you hand wash your dishes and still notice rust on the edges, it might be time to replace your drying rack.
When it comes to gray lines, you are most likely to find them on your plates. These marks can form when the dishes rub against metal. The usual culprit is none other than serrated metal knives. Take note that the discoloration can also form if your Corelle dishes are directly exposed to metal dishes in the dishwasher. The best way to lessen these marks is to avoid using steak knives on your dishes and loading your dishwasher in a way where the metal pots and pans do not come in contact with your dishes throughout the wash cycle.

Cleaning your Corelle dishes
Once your Corelle dishes have rust stains or gray marks, it is recommended to use a non-abrasive cleanser. If a sponge and minimal effort can’t remove the discoloration, you can use a nylon or plastic scrubber.
You can also mix your cleaning powder with a small amount of water to create a paste. Coat the paste evenly on the rust or gray stain and let it work for a few minutes before rinsing it away. Don’t use any abrasive tools such as a ball of steel wool, or other type of scouring pad, since these can cause lasting scratches on your dishes.
