How to Clean Hard Water Stains From a Sink or Faucet

 

 

 What You’ll Need

Distilled white vinegar

The star of the show — do not use apple cider or balsamic

An old cloth, rag, or paper towel

To trap the vinegar against the stain

Green/yellow scrub sponge

The green side gently scrubs without scratching

Optional: Baking soda

 

For extra scrub power on tough spots

 Pro Tip: Use distilled vinegar — it’s purer and more effective than filtered.

 Step-by-Step: How to Remove Hard Water Stains

Step 1: Soak the Stain

Pour distilled white vinegar onto a clean cloth or paper towel

Press the soaked cloth directly onto the stained area — faucet, sink rim, showerhead, or tile grout

Let it sit for 30–60 minutes

For light stains: 30 mins

For heavy buildup: 60 mins or more
