How to Remove Hard Water Stains from a Porcelain Sink

Hard water stains on a porcelain sink can leave cloudy, white marks that make the surface look dull and unclean. These stains are caused by mineral deposits, mostly calcium and magnesium, that build up when hard water evaporates. If you have hard water, you've probably seen these spots around the faucet or in the basin. The good news is that you can remove them with common household items like white vinegar and baking soda, without harsh chemicals. This guide will show you how to tackle both fresh and set-in stains, with important precautions for porcelain.

What to Do First

Before you start, identify the type of stain. Fresh water spots are usually light and powdery, while set-in stains are thicker and more stubborn. For fresh spots, a simple vinegar solution may be enough. For set-in stains, you'll need a paste and a little more patience. Always test any cleaning method on a small, hidden area of the sink first to make sure it doesn't damage the finish.

Method for Fresh Hard Water Spots

If the stains are fresh, you can often wipe them away with a vinegar solution. Here's how:

1. Mix equal parts white vinegar and water in a spray bottle.
2. Spray the solution directly onto the stained areas.
3. Let it sit for 5 to 10 minutes to loosen the mineral deposits.
4. Wipe with a soft cloth or sponge, using gentle circular motions.
5. Rinse thoroughly with water and dry with a clean towel.
