🧴 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

✅ Why soak? The vinegar needs time to penetrate and dissolve the minerals.
