Though porcelain itself doesn't rust, it can easily become the victim of rust stains if a rusty item gets too close. These stains can noticeably stand out and mar the appearance of your porcelain, making it less appealing to eat from. Rusty-looking porcelain isn't a sign that you need new dinnerware. With a minimal expenditure of effort on your part, your porcelain plates will quickly and almost effortlessly come clean.

Step 1
Set the plate on a flat surface.
Step 2
Pour white vinegar directly onto the stain so that it's covered with a small puddle. If the stain is on the edge and cannot be soaked this way, soak a cloth or sponge in white vinegar and set it on the stain.
Step 3
Allow the area to soak for at least 10 minutes.
Step 4
Wash the plate with warm, soapy water to rinse away the vinegar and rust.
Step 5
Dry the plate with a soft towel.
