The Essential Quartz Countertop Care Guide

How to Keep Your Surfaces Clean, Safe, and Looking Their Best

Quartz countertops are a perfect blend of modern style and everyday resilience. Their non-porous structure and natural resistance to stains make them a go-to option for busy kitchens and bathrooms. But like any high-quality surface, they’ll last longer and look better with the right care.

At World Stone, we want to help you protect your investment—here’s everything you need to know.

1. Simple Cleaning Is Best

Maintaining quartz doesn’t require expensive products or complicated routines. In fact, less is more.

What to use:

• A soft cloth or sponge

• Warm water

• A mild, non-abrasive household cleaner (without bleach or high pH)

What to skip:

• Scouring powders

• Steel wool or rough scrub pads

• Bleach-based or alkaline-heavy products

Even though quartz is non-porous, leftover residues can create dull spots over time—rinse and dry well after cleaning.

2. Handle Spills Swiftly

Although quartz resists most staining, some pigmented or acidic substances (like curry, wine, or tomato sauce) can discolor the surface if left too long.

If a spill happens:

• Wipe it up quickly with warm soapy water

• For stubborn messes like dried paint or gum, gently lift the residue using a plastic scraper, then clean the area as usual

Avoid abrasive scrubbers or metal tools—they may leave dull marks or fine scratches.

3. Don’t Push Its Heat Limits

Quartz performs well under daily use, but it’s not built for direct high-heat contact. Sudden changes in temperature can stress the material, sometimes causing cracks or discoloration.

Best practice:
Always use trivets or heat pads under hot pans, slow cookers, or any heat-emitting appliance. Never set anything straight from the oven onto the countertop.

4. Keep Sharp Objects in Check

Though quartz is tough, it’s not immune to damage from sharp or heavy items.

To keep your surfaces flawless:

• Always use a cutting board (even for small tasks)

• Refrain from dragging pots, metal utensils, or appliances across the surface

• Be mindful when handling heavy cookware or tools near edges and corners

5. Know Which Chemicals to Avoid

Certain cleaning agents and solvents can react with quartz resin binders and damage the finish.

Steer clear of:

• Paint removers or nail polish remover with acetone

• Oven cleaners, drain cleaners, and lye-based products

• Permanent markers, ink, and furniture polish

If an accident happens, rinse the surface with clean water immediately and wipe dry.

Final Thoughts

Quartz offers a great return on investment: durable, stylish, and easy to care for. With a little daily attention and some smart habits, your surfaces will maintain their polished look for years to come.

The Truth About Sealers: Should You Seal Your Natural Stone Countertops?

Natural stone countertops—like granite, marble, and quartzite—are known for their timeless beauty and durability. But should they be sealed? At World Stone, we follow the expert guidance of the Natural Stone Institute, and here’s what you should know.

Why Seal at All?

Sealing natural stone isn’t always necessary, but in many cases, it’s a smart move. Some stones are more porous than others, meaning they absorb liquids and are more susceptible to stains. A proper sealant adds a layer of defense without compromising the look or feel of the stone.

The Two Types of Sealants

1. Topical Sealers

What they do:
These sealers form a protective film over the surface of the stone. They’re usually made from wax, acrylic, or other plastics and work well at resisting surface moisture and some staining agents.

Pros:

• Quick and easy surface protection

• Can add shine (in some finishes)

Cons:

• Require frequent reapplication due to wear

• Can change the appearance of honed or matte stones

• Not ideal for most residential countertop applications

When to avoid:
Topical sealers are not recommended for honed or textured finishes. They can add an unwanted gloss and alter the stone’s intended aesthetic.

2. Impregnating (Penetrating) Sealers

What they do:
These sealers soak into the stone and bond below the surface. They don’t alter the finish but offer long-term resistance to staining by repelling liquids from within.

Types:

• Water-based: Easy to apply, low odor

• Solvent-based: Deeper protection and longer-lasting effects

Pros:

• Won’t affect the natural appearance of the stone

• Long-lasting protection

• Suitable for kitchen and bath surfaces

Cons:

• Slightly more complex application

• Some solvent-based sealers may require proper ventilation during use

At World Stone, we apply a professional-grade solvent-based impregnating sealer to all qualifying surfaces during installation. This ensures the stone starts off with a layer of protection that can extend its life and keep it looking great.

How Often Should You Reseal?

There’s no universal answer. Depending on your stone type, usage, and sealant product, reapplication may be needed every 1–5 years.

A simple test:
Place a few drops of water on the countertop. If the stone darkens within 5 minutes, it’s time to reseal.

Choosing the Right Sealer

We don’t recommend a specific brand, but we do strongly advise that you:

• Choose a sealer compatible with your specific stone

• Ensure the product is non-toxic and food-safe if used in the kitchen

• Follow the manufacturer’s instructions carefully for best results

• Avoid mixing chemical products (e.g., bleach and ammonia)

Final Thought

Sealing doesn’t make your countertops indestructible—but it does make them more resilient. When paired with regular care and smart cleaning habits, sealing helps your stone stay beautiful and functional for years to come.

Natural Stone Care: Cleaning, Stain Removal & Maintenance for Granite, Marble, and More

Natural stone countertops offer unmatched beauty and long-lasting performance—but they do require proper care to preserve their appearance. Whether you're dealing with a daily mess or an unexpected stain, this guide will walk you through the best practices for keeping your stone surfaces in top shape.

Routine Cleaning

Gentle Is Best

For day-to-day care, stick to simple and safe methods:

• Wipe down with a neutral pH stone cleaner or mild dish soap mixed with warm water.

• Use a soft cloth for countertops and a clean mop for floors—abrasive pads can scratch the surface.

• Avoid overusing soap, which can leave behind a hazy film. Rinse thoroughly and dry with a soft towel.

• In damp areas like showers or bathrooms, run a squeegee after each use to reduce soap scum buildup.

For outdoor stone (e.g., patios or pool areas), rinse with clear water and spot-clean with a diluted bleach solution to remove algae or moss buildup.

Cleaning Products to Avoid

Natural stone is sensitive to certain chemicals and cleaning habits. Keep these tips in mind:

• Avoid acidic cleaners like vinegar, lemon juice, or toilet bowl cleaners—they can etch marble and other calcareous stones.

• Steer clear of scouring powders or abrasive creams, which can scratch polished surfaces.

• Never use rust removers that contain hydrofluoric acid (HF)—this harsh chemical attacks even the strongest stones like granite.

• Don’t mix bleach and ammonia. Doing so creates a toxic gas that's harmful to breathe.

If you're ever in doubt, ask your stone supplier to recommend safe cleaning products.

Sealing: An Extra Layer of Protection

Some natural stones benefit from sealing to help resist stains. These sealers—more accurately called impregnators—soak into the stone and create a moisture barrier.

• Sealing doesn't make stone stain-proof, but it does buy you time to wipe up spills before they soak in.

• Use only non-toxic sealers in food prep areas.

• Always follow your supplier's guidance on how often to reseal, which may vary based on stone type and usage.

Identifying & Removing Stains

Before treating a stain, take a moment to investigate:

• Where is it located? Is it near a plant, food prep area, bathroom, or makeup station?

• What color is it? Different types of stains leave different marks.

• What shape or pattern does it have? Rust or metal stains often match the shape of the item that caused them.

• What’s nearby? Think about what activities or items are usually around the stained spot.

Once you’ve identified the likely source, use these targeted solutions:

Common Stone Stains & Treatments

Oil-Based Stains

Examples: grease, cosmetics, cooking oils, putty

• Appear as dark patches.

• Clean gently with mineral spirits, acetone, or a liquid detergent to lift the residue from the stone.

Organic Stains

Examples: coffee, tea, wine, fruit, food spills, paper, leaves

• May leave pinkish-brown discoloration.

• Indoors: Clean with 12% hydrogen peroxide and a few drops of ammonia.

• Outdoors: Sun and rain often help fade organic stains over time.

Metal Stains

Examples: rust from cans, screws, nails, furniture

• Rust appears orange to brown; copper turns green or muddy brown.

• Remove with a poultice—for deep rust stains, professional treatment may be needed.

Biological Stains

Examples: mildew, algae, moss, lichens

• Mix ½ cup bleach, ammonia, or hydrogen peroxide in a gallon of water.

Do not mix bleach and ammonia together.

Ink Stains

Examples: markers, pens

• On light stone, use hydrogen peroxide or bleach.

• On dark stone, try acetone or lacquer thinner.

Paint Stains

• Small spots can be scraped carefully with a razor or cleaned with lacquer thinner.

• For thick or dried paint, use a commercial paint stripper—but avoid acids and flame tools.

• Protect yourself with gloves and eye protection, and use only wood or plastic tools to scrape residue.

Hard Water Spots & Rings

• Usually surface-level and caused by mineral deposits.

• Buff gently with 0000-grade (super fine) steel wool.

Smoke & Fire Residue

• Fireplaces or smoke-stained areas may need a specialized smoke remover.

• Acidic residue from smoke can also dull the surface, requiring professional refinishing.

Etching

• Caused by acidic contact, even from things like juice or wine.

• Etching dulls the finish and may or may not leave a visible stain.

• Light etching can sometimes be polished out; deeper etching should be addressed by a stone restoration expert.

Scratches & Surface Dullness

• Light scratches can be improved with dry 0000 steel wool.

• Deeper gouges or chips require professional refinishing.

Final Thoughts

Natural stone countertops are a premium investment, and with the right care, they’ll reward you with decades of style and performance. Stick to gentle daily cleaning, avoid harsh chemicals, and learn how to respond to stains early. When needed, don’t hesitate to call in a stone care pro—some fixes are best left to the experts.

Do You Need Countertop Supports?

When it comes to extended countertop overhangs—like those on islands, peninsulas, or bar tops—proper support is key to both safety and long-term durability. At World Stone, we help customers determine when and where supports are needed and offer stylish, functional solutions to get the job done right.

---

When Are Supports Needed?

• Overhangs up to 10 inches:
  Supports are strongly recommended, especially with heavier materials like granite or quartz. While it may appear stable, unsupported weight over time can lead to cracks, sagging, or cabinet stress.

• Overhangs over 12 inches:
  Supports are required. At this length, the stone cannot safely support its own weight and must be reinforced with brackets or corbels to meet both safety standards and manufacturer guidelines.

Support Options We Offer

Wooden Corbels
Corbels offer both support and style. Available in various shapes and finishes, wooden corbels are ideal for traditional or farmhouse-style spaces. They add a decorative touch while giving your countertop the strength it needs.

Metal Brackets
World Stone offers custom-made metal support brackets for a clean, modern look. They are engineered for strength without drawing attention—especially useful when you want the stone to be the star. These low-profile supports are perfect for:

• Kitchen islands

• Floating bar tops

• Wall-mounted countertops or desks

• Open shelving or floating shelves

How many supports do you need?

• Countertop brackets are generally spaced 18 - 24 inches apart

• Bracket spacing starts 4 - 6 inches away from each end

Understanding Countertop Overhangs

When planning your countertops, overhangs are a key detail that affect both style and function. An overhang is the portion of the countertop that extends beyond the face of the cabinets—providing visual balance, comfort, and often a bit of extra workspace.

Standard Overhangs

• 1½-Inch Overhang (Standard):
  This is the most common overhang for kitchen countertops. It provides a clean look and slight coverage of the cabinet face while helping to catch crumbs and spills before they reach your cabinetry.

• 1-Inch Overhang:
  Popular in modern kitchens and apartment complexes, this minimal look creates a slim, streamlined feel. It works well in tight spaces or where a minimalist design is preferred.

Island & Peninsula Overhangs

• 2-Inch Overhang:
  Islands and peninsulas often receive a slightly deeper overhang to create symmetry, allow for trim around the kneewalls, and increase counter space.

• Bar Overhangs (10–12 Inches):
  When seating is incorporated, such as a breakfast bar or island seating area, the overhang is usually extended to 10 to 12 inches. This provides adequate knee space and comfort for people sitting at the counter.

Note: For any overhang greater than 10 inches, we strongly recommend using supports such as corbels or steel brackets to maintain stability and prevent sagging over time.

Visit our showroom or check our Products Page to pick from our selection of beautiful granite, marble, or quartz. Or check out options from our major suppliers. You can mix and match colors across different rooms to suit the function and style of each space.

---

Thickness

We’ll confirm the thickness of each stone (usually 3cm). This affects style, price, available edge profiles, and sometimes support requirements.

---

Backsplash Height

You decide how much backsplash (if any) you'd like—common options include a standard 4-inch backsplash, full-height, or a completely clean wall for tile.

---

Faucet Spread

For any sink installations, we’ll record your faucet configuration (typically 4", 8", or single-hole). This allows us to drill precise holes in advance for easy installation later.

---

Sink Selection & Cooktop Models

We offer a variety of sink options—from single bowls to 60/40 or 50/50 splits, as well as oval or rectangular vanities. You’ll check off what works for your space. If you already have your sinks or cooktops selected, we’ll take down those model numbers. This ensures cutouts are accurate and everything fits perfectly at install.

---

Edge Profile

Choose from a range of edge styles—like Straight, Quarter Round, Half Bullnose, Ogee, and more. These choices influence both the look and feel of your countertops.

---

Surface Finish

Would you like polished, leathered, or honed? Most material is only available in polished, but we’ll explain the pros and cons of each so you can pick the perfect finish for your home’s style and daily use.

---

Overhang & Radius

We’ll help you select the right overhangs, determine need for any supports, and define the corner radius (how rounded the corners are). This is especially important for islands, bar tops, or child-friendly homes.

---

Additional Notes

Anything unique? Whether you have special design requests, timing needs, or accessibility concerns—there’s space for that too.

---

Signature and customer expectations

Your Selections = Your Style
This design process is all about you. Our job is to guide and advise, but ultimately, you make the calls on what design works best for your home. With our expert team, you can be confident that every box checked brings you one step closer to a countertop you’ll love.

Corner Radius

What Is a Corner Radius?

Corner Radius refers to the shape of the corners where two edges meet—usually the outer points of islands, peninsulas, or exposed ends. A square (90°) corner has no rounding, while a 1" or 3" radius curves the corner to soften its appearance and make it safer in high-traffic areas.

How it’s measured:
The radius is the distance from the tip of the corner (where two edges meet) to where the curve starts. A 1" radius curves away from the corner by 1 inch on both sides, creating a smooth quarter-circle. The larger the radius, the more rounded the corner looks.

Standard Radius Options

At World Stone, we offer a range of corner radius options to match your style, layout, and how your space is used.

• ¼” Radius:
  A very subtle rounding that takes the sharp edge off without changing the overall square appearance. This option is ideal when you want a crisp, modern look with a touch of safety and comfort.

• ½” Radius:
  Slightly more noticeable than the soft corner, this size adds a gentle curve without making the corner feel overly rounded. It’s a great compromise between form and function.

• 1” Radius (Standard):
  This is our go-to for overhangs of 1½” inches or more, offering a clean, rounded look that blends style with safety. It’s large enough to soften the corner visually and physically, yet still maintains a refined aesthetic.

• 3” Radius:
  A bolder, sweeping curve that’s ideal for extended overhangs on islands or bar tops. It not only enhances comfort but also adds a casual, welcoming feel to open kitchen layouts.

• Square (90°):
  Typically used where countertops meet walls, appliances, or backsplashes, this option has no rounding at all. While clean and sharp, it’s best reserved for corners that are tucked away from foot traffic.

• Custom Radius:
  Looking for something unique? We can create custom corner curves tailored to your specific preferences or space constraints. Just let us know what you envision, and we’ll make it happen.
