I finally learned how the right way to remove hard water stains from my sink, and it worked like a charm.

How to Remove Hard Water Stains from a Sink 

Materials You’ll Need:

• White vinegar
• Baking soda (optional for tough stains)
• A spray bottle
• A clean cloth or sponge
• An old toothbrush (for scrubbing edges and tight areas)
• Lemon (optional for extra shine and scent)

Step-by-Step Method:

1. Spray Vinegar on the Stains
   • Fill a spray bottle with white vinegar (no need to dilute).
   • Spray the vinegar directly onto the hard water stains in your sink.
   • Let it sit for 5–10 minutes. The acidity in vinegar helps dissolve the mineral deposits like calcium and lime.
2. Scrub Gently
   • Use a sponge or soft cloth to scrub the area.
   • For corners, edges, or around the faucet, use an old toothbrush to get in tight spaces.
3. For Tough Stains: Add Baking Soda
   • If some stains are still visible, sprinkle baking soda on the stained areas after spraying vinegar.
   • The baking soda will fizz with the vinegar, helping lift stubborn deposits.
   • Let it sit for another 5 minutes, then scrub again.
4. Rinse Thoroughly
   • Rinse the sink with clean water to wash away the vinegar and loosened minerals.
   • Wipe dry with a cloth to prevent new water spots from forming.
5. Optional: Rub with Lemon for Shine
   • For a natural shine and fresh scent, rub a cut lemon over the sink surface.
   • This also helps break down any remaining residue and leaves your sink looking polished.

Why It Works:

• Vinegar is acidic and breaks down calcium and lime from hard water.
• Baking soda acts as a mild abrasive to lift tough buildup without scratching.
• Lemon juice adds extra acid and polish for a clean finish.

Summary:

Using white vinegar (and optionally baking soda), you can easily remove hard water stains from your sink. It’s natural, safe, and surprisingly effective!
