How to Clean Sandstone Pavers: Expert Advice for Long-Lasting Beauty

Imagine stepping into your backyard, coffee in hand, to admire your sandstone pavers. The warm, earthy tones of the stone glow in the morning light, creating a serene oasis. 

But wait—those stubborn stains from last week’s BBQ are still there, and patches of moss are creeping into the corners. Sound familiar? But the question is how to clean sandstone pavers.

Don’t worry! With the right care, your sandstone pavers can stay as stunning as the day they were installed. At MTP Stone, we’ve helped countless Australian homeowners preserve the natural beauty of their sandstone surfaces. Now, it’s your turn; let’s get started!

Why Does Sandstone Deserve Your Attention?

Sandstone is not just another building material; it’s a natural art. Each plate of compressed sand and minerals, formed over millions of years, contains unique patterns and colors that give the character of the house. However, its porous nature means it is more susceptible to dirt, spills, and weathering than tiles and concrete.

In Australia’s climate, from wet coastal regions to dusty outback regions, sandstone faces unique challenges.

• Coastal House: Salt sprays can affect the surface of stones over time.
• Rain area: Constant moisture promotes mold and algae growth. 
• Heavy traffic areas: Dirt and grit, grinding his finish with stones and dulling it.

Regular cleaning is more than just an aesthetic. It’s about protecting your investment. A well-maintained sandstone benchtop can take up to several years!

Essential Tools & Materials

Before you start scrubbing, let’s gather your toolkit. Think of this as your “stone care first-aid kit”:

Basic Supplies

• Soft-bristle broom or brush: Avoid wire brushes—they’re too harsh!
• Garden hose or bucket: For gentle rinsing.
• pH-neutral stone cleaner: Specifically designed for natural stone.
• Microfiber cloths: Perfect for indoor sandstone benchtops.
• Protective gloves: Keep your hands safe from cleaning solutions.

For Tough Stains

• Baking soda or cornstarch: Absorbs oil and grease.
• White vinegar (diluted): Fights mold and mildew.
• Poultice powder: Available at hardware stores for deep stains.

Optional but Helpful

• Stone sealant: A game-changer for long-term protection.
• Soft wash system: A low-pressure alternative to harsh pressure washers.

Pro Tip: Always test cleaning solutions on a small, hidden area first!

Step-by-Step Guide to Cleaning Sandstone Pavers

Here are step-by-step guidelines on how to clean sandstone pavers easily. Let’s have a look below!

Step 1: Clear the Surface

Start by sweeping away loose debris like leaves, dirt, and twigs. If you skip this step, you’ll end up grinding grit into the stone during washing, which can cause scratches. For sandstone benchtops, wipe crumbs with a dry cloth.

Step 2: Pre-Treat Stains

• Oil or Fat: Sprinkle baking powder or cornstarch over the stain. Sit overnight to absorb the oil and polish it.
• Mold or Algae: One part of white vinegar mixes with 3 parts of water. Lightly spray the area and let it sit for 10 minutes.

Step 3: Mix Your Cleaning Solution

Combine with hot water and a pH-neutral stone cleaner (follow the label instructions). Avoid dish soap if possible—it can leave a filmy residue. For outdoor pavement stones, add detergent containing stone slices to the stone bucket.

Step 4: Scrub Gently

Dip your soft brush into the solution and work in small sections. Use circular motions for stubborn stains, but don’t press too hard—sandstone is softer than granite or marble.

Step 5: Rinse Thoroughly

Use a garden hose on a low setting to rinse away dirt and cleaner. For indoor sandstone benchtops, wipe with a damp microfiber cloth. Ensure no soap residue remains—it can attract more dirt.

Step 6: Dry Completely

Let the pavers air dry for 12–24 hours. Avoid walking on them while wet to prevent slips and watermarks.

Step 7: Apply Sealant (The Secret to Longevity)

Once dry, apply a penetrating stone sealant. This creates an invisible barrier against stains, UV rays, and moisture. Reapply every 1–2 years for outdoor pavers and every 2–3 years for indoor surfaces.

5 Costly Mistakes to Avoid 

1. Using Acidic Cleaners (Like Bleach or Lemon Juice): Acid erodes the stone’s calcium carbonate, causing pitting and discoloration. Stick to pH-neutral products.
2. Pressure Washing on High Settings: High-pressure water blasts away the stone’s soft layers, leaving a rough, uneven surface. If you must pressure wash, use a fan tip and keep the nozzle at least 30 cm away.
3. Ignoring Spills: Red wine, coffee, or oil can seep into unsealed sandstone within minutes. Blot spills immediately with a paper towel—never wipe, as this spreads the stain.
4. Skipping Sealant: Unsealed sandstone is like a sponge—it absorbs everything! Sealant makes cleaning easier and prevents 90% of stains.
5. Using Abrasive Tools: Steel wool, stiff brushes, or scrubbing pads will scratch the stone. Opt for soft materials instead.

Caring for Indoor Sandstone Benchtops

Your kitchen’s sandstone benchtop is the heart of your home, but it needs special care:

Daily Maintenance

• Wipe spills immediately with a damp cloth.
• Use coasters under glasses to prevent water rings.
• Clean with a stone-safe spray or mild soapy water.

Deep Cleaning

• For food stains, make a paste of baking soda and water. Apply it, let it sit for 10 minutes, and then rinse.
• Disinfect with diluted vinegar (1:3 ratio), but rinse thoroughly afterward.

Heat & Scratch Protection

• Always use trivets or mats under hot pans. Sandstone can crack under sudden temperature changes.
• Avoid cutting directly on the surface. Use a chopping board to prevent scratches.

Sealing Tips

• Choose a food-safe, non-toxic sealant for benchtops.
• Reapply sealant every 2–3 years or when water no longer beads on the surface

FAQs

Q:- Can I use a steam cleaner on sandstone?

Q:- How do I remove rust stains from sandstone? 

Ans:- Use a commercial rust remover designed for natural stone. Avoid acidic products!

Q:- Is sandstone slippery when wet? 

Ans:- Sealed sandstone has a textured surface, making it slip-resistant. Unsealed stone can be slippery—another reason to seal!

Q:- Can I paint or resurface my sandstone pavers? 

Ans:- We don’t recommend it—paint traps moisture. Instead, restore the stone with professional cleaning.

Q:- Why does my sandstone look darker after cleaning? 

Ans:- This is normal! Water highlights the stone’s natural color. It will lighten as it dries.
