How to Get Rid of Hard Water Stains on Your Stainless Steel Sink

Hard water deposits often leave behind stubborn, cloudy spots on stainless steel fixtures and appliances, from faucets and sinks to refrigerators and microwaves.

Though these white streaks don’t usually impact an appliance’s performance, they can diminish its overall appearance.

The good news? Removing hard water stains is simpler than you might think—and you likely already have the supplies you need.

Ahead, cleaning experts share four tried-and-true methods for erasing hard water stains and restoring your stainless steel’s natural shine.

Why Hard Water Stains Appear on Stainless Steel

Hard water contains high concentrations of minerals such as calcium and magnesium.

When the water evaporates, these minerals remain on the surface, creating white, cloudy spots and streaks. Over time, these deposits accumulate and become more noticeable..

Essential Materials

Gather the following items before you begin:

  • White vinegar
  • Water
  • Baking soda
  • Club soda
  • Microfiber cloths
  • Spray bottle
  • Small bowl

1. Using Vinegar

White vinegar’s acidity effectively breaks down mineral deposits and lifts them from stainless steel.

Steps:

  1. Mix equal parts white vinegar and water in a spray bottle.
  2. Spray the solution onto the stains and let it sit for 5–10 minutes.
  3. Gently scrub with a microfiber cloth or sponge.
  4. Rinse thoroughly with clean water.
  5. Dry with a clean microfiber cloth to prevent new water spots.

2. Using Lemon

No vinegar on hand? Lemon juice’s natural acidity makes it an excellent alternative.

Steps:

  1. Cut a lemon in half.
  2. Rub the cut side over the stained area and let the juice sit for 5–10 minutes.
  3. Gently scrub with a soft microfiber cloth.
  4. Rinse thoroughly with clean water.
  5. Dry with a clean microfiber cloth to avoid spotting.

3. Using Baking Soda

For tougher stains, combine baking soda with vinegar and water for a more powerful cleaning paste.

Steps:

  1. In a small bowl, mix ¼ cup baking soda with ½ cup water to form a paste.
  2. Apply the paste to the stains.
  3. Lightly spray the area with white vinegar.
  4. Once it foams, scrub with a microfiber cloth.
  5. Rinse well with clean water.
  6. Dry thoroughly to prevent new deposits from forming.

4. Using Club Soda

Club soda’s carbonation can help loosen mineral buildup and lift it away from stainless steel.

Steps:

  1. Pour club soda directly onto the stains.
  2. Scrub gently with a microfiber cloth.
  3. Wipe dry with a clean microfiber cloth to prevent water spots.

How to Prevent Hard Water Stains on Stainless Steel

Regular maintenance is the key to preventing future buildup.

After use, wipe down your stainless steel surfaces with a soft cloth and mild detergent, then dry thoroughly to avoid water spots.

Always avoid abrasive pads or harsh cleaners.

With these expert-approved methods, you’ll keep your stainless steel surfaces sparkling, even when hard water poses a challenge.
