Causes of color changes on Corelle dishes

If you find rust stains on your Corelle dishes, the cause is typically your dishwasher. The brackets in most dishwashers are made of metal and treated in vinyl to protect them from rust. Over time, this vinyl layer will start to chip or peel away.

Once this occurs, the dishwasher rack starts to rust, potentially transferring the rust to your Corelle dishes. As a result, your dishes end up with small but noticeable rust spots on the rims or edges of the dishes. If you wash dishes by hand and notice rust on the edges, it might be time to replace your drying rack. 

Steps on how to remove rust stains from Corelle dishes

Whether you have rust stains or gray marks on your Corelle dishes, the cleaning approach is the same. 

  • Wet the dishes and sprinkle a non-abrasive cleanser on the site of the discoloration. 
  • If scrubbing on the site of the stains is not enough, you can use a nylon or plastic scrubber. You can even combine your cleaning powder with some water to create a paste.
  • Dab on the paste on the site and leave in place for a few minutes before rinsing thoroughly.
  • Avoid using any abrasive tools such as scouring pads or steel wool since these can cause permanent scratches on your dishes.

This is a vital point to remember in prolonging its lifespan. Avoid pouring water directly into a hot Corelle pot since it might shatter. If leftover food residue is hard to remove, scrub using a non-abrasive cleanser and nylon scrub pad.
