Maintaining stone countertops may seem straightforward, but there’s a surprising amount of misinformation circulating about how to care for them properly. While these surfaces are known for their beauty and durability, improper maintenance habits—often based on myths—can lead to damage, discoloration, or premature wear. From sealing to stain removal and cleaning techniques, knowing what’s true (and what’s not) can help homeowners preserve their investment for years to come. With the U.S. demand for countertops expected to rise 2.4% annually through 2028, according to the Freedonia Group, understanding the right care methods is more important than ever. In this guide, we’ll debunk some of the most common myths and reveal practical advice to keep your stone countertops in top shape.

Myth 1: Assume Stone Is Indestructible

Natural stone may feel solid and durable, but it’s not invincible. Granite, quartzite, and marble each have different levels of hardness and resilience. Chipping, cracking, or etching can occur if proper precautions aren’t taken. That means avoiding activities like standing on countertops or dropping heavy objects directly on the surface.

Acidic substances like vinegar, lemon juice, or wine can leave dull spots or etch marks on more porous stones. These effects are often permanent if not addressed quickly. Always use cutting boards and coasters to shield your counters from damage.

Thermal shock is another risk. While many stone countertops are heat-resistant, placing a hot pot directly on the surface can cause stress cracks. Use trivets and heat pads to minimize exposure to extreme temperature changes and preserve the integrity of your counters.

Myth 2: Skip the Sealing Process

One of the most misunderstood aspects of stone countertop care is sealing. Many assume sealing is optional, but it’s a necessary line of defense against stains and moisture. Natural stones like granite and marble are porous and can absorb liquids without this protective layer.

There are different types of sealers—penetrating sealers soak into the stone, while topical sealers sit on the surface. Depending on usage, we have found that some sealers need to be reapplied every six months, while others can last for several years. Choosing the right product based on stone type and use is key.

To test if your countertop needs resealing, sprinkle a few drops of water on the surface. If it absorbs quickly or leaves a dark spot, it’s time to reseal. This simple test helps homeowners act before stains and damage occur, extending the life and beauty of their stone countertops.

Myth 3: Use Any Household Cleaner

General-purpose cleaners may work on other surfaces, but they can degrade natural stone. Harsh or acidic cleaning agents can etch the surface, dull the finish, or strip away the protective sealant. This is especially true for cleaners containing lemon, vinegar, ammonia, or bleach.

Avoid abrasive scrubbing pads or powders as well. These can scratch the surface, especially on softer stones like marble. Even small particles in common cleaners can leave lasting marks.

Instead, stick with a soft cloth or sponge and a pH-neutral cleaner designed specifically for stone. These products clean without compromising the structural or aesthetic integrity of your stone countertops. Routine gentle cleaning maintains clarity and shine while protecting your investment from wear.

Myth 4: Believe Stains Are Permanent

Many homeowners panic at the sight of a deep-set stain, assuming it’s permanent. But most stains—whether from oil, red wine, or ink—can be removed with the right technique. The key is identifying the type of stain and choosing an appropriate cleaning method.

For example, oil-based stains can be pulled from porous stone with a baking soda poultice. Organic stains might require a hydrogen peroxide-based treatment. Each approach targets specific substances without damaging the surrounding surface.

Preventing stains starts with sealing, but also includes regular maintenance like using coasters, blotting spills immediately, and cleaning gently. Educating yourself on stain removal gives you confidence and control over how your stone countertops age over time.

Myth 5: Ignore Dark Stone Maintenance

Dark-colored stone countertops are often chosen for their ability to hide stains and imperfections. However, this visual advantage doesn’t mean they’re maintenance-free. Dark stones can still suffer from scratches, fading, and surface damage over time.

Soapstone, for instance, is less likely to etch but can scratch easily. Granite may handle wear better, but UV exposure can cause fading. Regular cleaning and protective measures still apply regardless of color.

For stones like soapstone, periodic applications of mineral oil can help maintain their deep color and even out wear. Consistent upkeep ensures your dark stone remains as visually striking as the day it was installed.

Myth 6: Trust Vinegar and Citrus as Natural Cleaners

It’s easy to assume that natural products like lemon juice or vinegar are safe for all surfaces, but they’re a big no for stone countertops. These acidic substances can etch and dull the finish of marble, limestone, and other sensitive stones.

While vinegar and citrus may appear to leave the surface shiny at first, the long-term damage includes weakening the stone and stripping sealants. The result is often dull spots or a worn-down surface.

Instead, opt for pH-balanced, stone-safe cleaning products or mild dish soap with warm water. If you prefer DIY solutions, make sure they’re gentle and non-abrasive. Your stone countertops will thank you in the long run with continued brilliance and durability.

Myth 7: Expect Scratch-Proof Surfaces

Many people believe that once installed, their stone countertops are completely scratch-proof. While granite and quartzite are very hard, no stone is entirely immune to scratches, especially softer varieties like marble or soapstone.

Daily kitchen activities—like dragging dishes or cutting directly on the counter—can result in fine scratches or dull spots. Over time, these small marks accumulate, diminishing the finish and overall appearance.

To prevent this, always use cutting boards and avoid sliding heavy cookware across the surface. Regular dusting also helps, as even tiny grit particles can act like sandpaper under pressure. Being cautious ensures your countertops remain pristine.

Myth 8: Think Magic Solutions Will Fix Everything

When a stain appears or etching occurs, many people turn to commercial "magic" products promising instant restoration. Unfortunately, most of these products oversimplify the problem or contain ingredients that could worsen the damage.

Each stone surface reacts differently based on its composition, finish, and existing condition. Using a one-size-fits-all solution may result in further staining, erosion, or residue buildup.

Instead, consult professionals or use proven cleaning and restoration methods tailored to your specific stone type. When in doubt, a custom approach always trumps a quick fix—especially when you're working to preserve the value and appearance of your stone countertops.

Caring for stone countertops doesn’t need to be overwhelming, but it does require separating fact from fiction. Myths about durability, maintenance, sealing, and cleaning can lead to unintentional damage if followed blindly. With proper sealing, gentle cleaning products, and a mindful daily routine, your stone surfaces can maintain their beauty and function for decades. As the demand for stone countertops continues to grow, especially in both residential and commercial settings, the importance of proper care can’t be overstated.
