Corelle dishes are known for their durability. They are resistant to cracks, chips and breakage. They are microwaveable, as well as dishwasher-safe. Corelle dishes are made of laminated layers of glass that are fused together. Since they don't contain metal, these dishes cannot rust. However, if they are stacked in the dishwasher so they touch a metal pan or utensil that rusts, the Corelle dishes can get rust on them. The same can hold true if they are stacked in the sink with a wet metal item that rusts.
To Remove Dishwasher Rust Stains
Moisten the sponge under tap water so it's wet, but not dripping.
Sprinkle a little kitchen cleanser on the sponge.
Rub the rust stains on the Corelle dishes gently with the cleanser. Apply more non-abrasive kitchen cleanser to the sponge if needed.
Rinse the cleanser and the rust stains immediately off under tap water.
To Remove Stubborn Dishwasher Rust Stains
Clean stubborn rust stains off Corelle dishes by applying a paste. Sprinkle some powder cleanser into the palm of your cupped hand.
Add a few drips of water -- just enough to make a paste. Mix the cleanser and the water together with your finger.
Dab the paste generously on the dishwasher rust stains. Allow the cleanser to set for one minute. Watch a clock or set a kitchen timer.
Rub the stubborn dishwasher stains gently with a wet sponge. Rinse the cleanser and the rust off the Corelle dishes thoroughly under tap water.
