How To Remove A Water Stain On Granite: Step-By-Step Guide

Introduction

Have you ever noticed cloudy rings or dark spots on your beautiful granite countertop and wondered how to get rid of them? These marks are usually water stains, and while granite is durable, it can still absorb moisture and leave behind unsightly spots.

To remove a water stain on granite, first dry the surface thoroughly, then apply a baking soda poultice or specialized granite cleaner, let it sit, and wipe clean. Most stains can be removed with this method without damaging the stone.

In this guide, I’ll show you step-by-step how to remove water stains from granite, share some effective home remedies, and give tips to prevent stains in the future.

What Causes Water Stains on Granite?

Before fixing the problem, it helps to understand why it happens:

• Mineral Deposits: Hard water leaves behind minerals like calcium and lime.
• Porosity of Granite: Even though granite is dense, it can absorb liquids if not sealed properly.
• Soap or Cleaner Residue: Harsh cleaners can trap water and create dull patches.

Knowing the cause helps you pick the right removal method.

Step-by-Step Guide: How To Remove A Water Stain On Granite

1. Clean and Dry the Surface

• Wipe the countertop with a soft microfiber cloth.
• Use warm water and mild dish soap (avoid acidic cleaners).
• Dry thoroughly with a towel.
  Tip: Never use vinegar or lemon juice on granite—they can etch the surface.

2. Try a Simple Buffing Method

• Take a dry microfiber cloth.
• Gently rub the stained area in circular motions.
• Often, surface-level water rings will fade with light buffing.

3. Apply a Baking Soda Poultice (Best for Deeper Stains)

This method pulls out moisture trapped inside the granite.

You’ll need:

• Baking soda
• Water
• Plastic wrap
• Painter’s tape

Steps:

1. Mix baking soda with water to create a thick paste.
2. Apply the paste directly to the stain.
3. Cover with plastic wrap and tape the edges.
4. Let it sit for 24 hours.
5. Remove the wrap, wipe away the paste, and dry the area.

4. Use a Granite-Safe Cleaner

• Buy a pH-balanced cleaner designed for stone surfaces.
• Spray on the stain and let it sit for 5 minutes.
• Wipe clean with a soft cloth.

Recommended when:

• The stain is light.
• You want a quick, safe solution.

5. For Stubborn Stains: Use a Poultice Powder

If baking soda doesn’t work, you can buy a commercial poultice powder for granite.

Steps:

• Mix according to the instructions.
• Apply over the water stain.
• Cover and leave for 24–48 hours.
• Remove and clean.

This is often used by professionals and works well for tough stains.

6. Reseal the Granite (Prevention Step)

Once the stain is gone, sealing your granite will help prevent future water rings.

How to Seal Granite:

1. Clean the surface thoroughly.
2. Apply granite sealer evenly with a cloth.
3. Let it sit for 15 minutes.
4. Buff with a clean, dry cloth.

Seal every 1–2 years depending on usage.

Real-Life Hacks to Keep Granite Spot-Free

• Always use coasters under glasses.
• Blot spills immediately, don’t wipe (prevents spreading).
• Dry the surface after cleaning instead of letting it air-dry.
• Avoid leaving wet sponges or bottles on granite overnight.

FAQs About Removing Water Stains from Granite

1. Can I use vinegar to remove water stains from granite?

No. Vinegar is acidic and can damage granite by dulling its finish. Always use pH-neutral cleaners.

2. How long does it take for a baking soda poultice to work?

It usually takes 24 hours, but very stubborn stains may require 48 hours.

3. Will sealing granite stop all water stains?

Sealing makes granite more resistant to stains but doesn’t make it completely stain-proof. You still need to clean spills quickly.

4. What if the stain won’t go away?

If a poultice doesn’t work, contact a professional stone restoration service. They have specialized tools for deep cleaning.

5. How often should I reseal granite countertops?

Every 1–2 years is recommended, depending on how often the surface is used.

Final Thoughts

Water stains on granite are frustrating but completely manageable. By cleaning, applying a baking soda poultice, and resealing, you can restore your granite’s shine and prevent future stains.
