Granite is one of the most durable and luxurious natural stones used in homes and businesses. It’s prized for its rich colours, unique patterns, and incredible strength. It resists heat, scratches, and daily wear, making it ideal for benchtops, floors, and vanities. But despite its toughness, granite still needs regular care. Over time, exposure to spills, dirt, and foot traffic can cause it to lose its shine.
If granite isn’t cleaned and maintained properly, it can develop stains, dull spots, and even cracks. Simple neglect or using the wrong products can accelerate wear, making the stone look tired and worn out. But with the right approach, you can keep your granite looking pristine.
Proper stone cleaning techniques remove grime, enhance natural beauty, and protect the stone for the long run. Whether you have polished black granite in your kitchen, a textured finish in your bathroom, or a high-gloss granite floor in a commercial space, knowing how to restore and maintain its brilliance is key.
This guide will walk you through the causes of granite damage, expert restoration techniques, and the best practices to keep your stone looking brand new.
1. Why Does Granite Lose Its Shine?
Granite might be strong, but it’s not immune to damage. Over time, even well-maintained granite can start to look dull. This happens for several reasons.
Main Causes of Granite Deterioration
- Acidic Substances – Vinegar, citrus juices, wine, and even some household cleaners can cause etching, dulling the surface over time.
- Staining from Liquids – Unsealed granite can absorb oils, coffee, wine, and other liquids, leaving unsightly marks.
- Residue from Improper Cleaning Products – Dish soap, bleach, and ammonia-based cleaners leave a film that builds up, creating a cloudy or hazy appearance.
- Scratches from Grit and Dirt – Tiny particles of dirt and sand act like sandpaper, gradually wearing down the polished surface.
- Lack of Sealing – Without a proper seal, granite becomes vulnerable to moisture, making it easier for stains and bacteria to penetrate.
Granite’s beauty depends on proper care. A polished surface reflects light and enhances its deep, natural tones, but neglect can strip away its brilliance. If your stone has lost its lustre, a professional granite restoration process can bring it back.
2. The Best Way to Restore Granite’s Shine
Restoring granite isn’t about using stronger chemicals or scrubbing harder—it’s about using the right techniques. Here’s a step-by-step guide to bring back the natural shine.
Step 1: Deep Cleaning the Surface
Before polishing or sealing, the granite must be free from dirt, grime, and residue. Follow these granite cleaning tips to prepare the surface:
- Use a pH-neutral stone cleaner or a mix of warm water and mild dish soap.
- Avoid abrasive sponges or scouring pads that can scratch the surface.
- For tough grime, apply a paste of baking soda and water, let it sit for 10 minutes, then wipe clean with a microfibre cloth.
Step 2: Polishing Granite Surfaces
Once the surface is clean, the next step is polishing granite surfaces to restore the shine.
- Use a granite polishing compound specifically designed for natural stone.
- Apply it in circular motions using a buffing pad or soft cloth.
- Wipe away excess residue and check the reflection. If the surface still looks dull, repeat the process.
Professional natural stone polishing involves diamond abrasives to smooth out microscopic imperfections, but for mild dullness, a home polishing method can be effective.
Step 3: Sealing for Protection
Sealing prevents stains, moisture absorption, and bacterial growth. If your granite absorbs water instead of repelling it, it’s time to re-seal.
- Apply a penetrating sealer evenly over the surface.
- Let it sit for 10-15 minutes, then wipe off the excess.
- Allow 24 hours for full curing before using the surface again.
Sealing is a critical step in professional granite maintenance and should be done every 6 to 12 months depending on usage.
3. How to Remove Stains from Granite
Even sealed granite can develop stains if spills aren’t cleaned up quickly. The secret is knowing how to treat each type of stain properly.
Common Granite Stains and Their Solutions
- Oil-Based Stains (Cooking Oils, Grease, Makeup): Apply a paste of baking soda and water, cover with plastic wrap, and let sit overnight. Wipe clean in the morning.
- Organic Stains (Wine, Coffee, Tea, Fruit Juice): Mix hydrogen peroxide with a few drops of ammonia and gently rub the stain with a cloth.
- Rust Stains (From Metal Objects): These stains can be stubborn and often require expert granite repair services.
- Water Spots and Hard Water Deposits: Buff with a dry microfibre cloth or use a specialised granite cleaner.
If stains persist, a professional deep clean granite treatment may be necessary.
4. Preventing Long-Term Granite Damage
Preventative care keeps granite looking fresh for years. A few simple habits can make a big difference.
Daily and Weekly Granite Care Guide
- Wipe down surfaces daily with a soft cloth and a pH-neutral cleaner.
- Use coasters, trivets, and placemats to prevent heat and moisture damage.
- Avoid acidic or abrasive cleaners.
- Reseal regularly to maintain protection.
What to Do About Scratches and Cracks
- Minor Scratches: Use a fine polishing powder to smooth them out.
- Deep Scratches: These require granite refinishing techniques by professionals.
- Cracks and Chips: Repair granite cracks immediately with a stone epoxy to prevent further damage.
5. When to Call a Professional for Granite Restoration
If granite surfaces remain dull or stained despite proper care, professional restoration may be necessary.
Signs It’s Time for Expert Help
- Stains won’t lift even after multiple treatments.
- Deep scratches or chips affect the surface.
- Granite appears hazy or uneven after polishing.
- The sealant has completely worn off.
Case Study: Restoring a High-Traffic Granite Floor
A corporate office in Sydney had a granite floor restoration project after years of wear left their reception area looking dull. Foot traffic had worn down the polished finish, and cleaning staff had used the wrong products, leaving streaks and residue. A professional restoration team deep-cleaned the floors, polished them with diamond abrasives, and sealed the surface. The result was a flawless, high-gloss finish that enhanced the professional look of the space.
