How to get rust out of porcelain

Patch-test white vinegar first; if the porcelain tolerates it, blot gently with vinegar and salt, but stubborn rust may need a commercial product made for this.

Patch-test white vinegar on an inconspicuous area before treating the rust.
Blot the stain with a clean cloth dampened with cool water and a small amount of dish soap.
Rinse the area with cool water and blot dry with a clean cloth.
Sprinkle salt on the rust stain, then dampen the salt with white vinegar.
Blot the area gently with a clean cloth; use a soft brush with light pressure only if needed.
Rinse thoroughly with cool water and blot dry.

Don't do this

Do not skip the patch test; porcelain may not tolerate every treatment.
Do not use abrasive scrubbing; it can scratch and dull porcelain.
Do not rub the stain; blot instead to reduce wear on the surface.
Do not keep working if the porcelain looks dulled or changed; rinse with cool water and stop.

If the patch test is not safe or the rust remains after gentle cleaning, use a commercial product made for this, used per its label. Stop before using abrasive force, because it can scratch and dull porcelain.
