How to Clean Hard Water Stains From Porcelain

Hard water can leave calcium and other mineral deposits on porcelain sinks and fixtures. These spots usually appear white, but may look like a hazy or dull area on porcelain. Harsh abrasives and acids can damage the surface of porcelain fixtures, but milder solutions remove the water spots without harming the porcelain. The acid breaks down the minerals in the hard water spots, and the abrasive scrubs them away once they have been softened.

  1. Wipe the surface with a damp cloth. Remove any dust or surface grime completely from the porcelain.

  2. Combine equal parts distilled white vinegar and baking soda to form a paste.

  3. Spread the paste on the water-spotted area. Let it stand for five minutes.

  4. Scrub the area lightly with a dampened cloth. Rinse with clear water. Repeat if some water spots are still visible on the porcelain surface.
