5 Common Myths About Granite Countertops Debunked

Introduction

Granite countertops remain one of the most popular choices for kitchens and bathrooms across Canada, prized for their durability, beauty, and value. However, despite their widespread use, many misconceptions persist about granite care and maintenance. These myths can lead homeowners to make mistakes that compromise the longevity and appearance of their investment.

In this article, we'll separate fact from fiction and debunk five of the most common myths about granite countertops. Understanding the truth will help you properly care for your surfaces and enjoy their beauty for decades to come.

Myth #1: Granite Countertops Never Need Sealing

The Myth:

One persistent myth is that granite is completely impervious to liquids and stains, eliminating the need for sealing. Some believe that granite's hardness makes it naturally stain-resistant without any additional protection.

The Truth:

While granite is indeed one of the less porous natural stones, it still contains microscopic pores that can absorb liquids and oils, potentially leading to staining. The porosity level varies depending on the specific type and color of granite—lighter colors are typically more porous than darker varieties.

Even the densest granite benefits from periodic sealing to maintain its stain resistance. A quality sealer creates an invisible barrier that prevents liquids and oils from penetrating the stone while allowing it to breathe. Most granite countertops should be sealed every 1-3 years, depending on use and the specific stone variety.

Myth #2: Granite Is Heat-Proof

The Myth:

Many homeowners believe that granite countertops are completely impervious to heat damage, making trivets and hot pads unnecessary.

The Truth:

While granite is indeed highly heat-resistant—far more so than laminate, solid surface, or quartz materials—it's not completely immune to heat damage. Granite can withstand brief contact with hot pots and pans, but prolonged exposure to extreme heat can have consequences:

• It can weaken the sealer, compromising stain resistance
• Extreme temperature changes (thermal shock) can potentially cause small fissures
• Some granite contains mineral deposits that may be affected by high heat

As a best practice, always use trivets or hot pads under extremely hot cookware, especially for items coming directly from the oven or that will remain in place for extended periods.

Myth #3: Acidic Cleaners Are Safe for Granite

The Myth:

Some homeowners believe that all-purpose cleaners, vinegar solutions, or lemon-based products are effective and safe for granite countertop cleaning.

The Truth:

Acidic cleaners are among the worst choices for granite surfaces. While granite is less susceptible to acid etching than marble, prolonged or frequent exposure to acidic substances can:

• Degrade and wear away the protective sealer
• Eventually dull the surface's polish
• Potentially etch the stone with repeated exposure

For daily cleaning, use only cleaners specifically formulated for granite or a simple solution of mild dish soap and warm water. Always rinse thoroughly and dry with a soft cloth to prevent water spots and streaking.

Avoid cleaners containing vinegar, lemon juice, ammonia, bleach, or abrasives. These can damage both the sealer and potentially the stone itself over time.

Myth #4: Granite Is Maintenance-Free

The Myth:

A common misconception is that granite requires no special care or maintenance beyond routine cleaning.

The Truth:

While granite is certainly one of the lower-maintenance countertop options, it does require some specific care to maintain its beauty and integrity:

• Regular cleaning: Daily wiping with an appropriate cleaner
• Periodic resealing: Every 1-3 years depending on use and granite type
• Prompt spill cleanup: Especially for acidic substances, oils, or deeply colored liquids
• Avoiding certain products: No harsh chemicals or abrasive cleaning tools

Proper maintenance is relatively simple and minimal compared to many other surfaces, but it's not entirely maintenance-free. The good news is that with proper care, granite countertops can look spectacular for decades.

Myth #5: All Granite Is Created Equal

The Myth:

Many consumers believe that all granite is essentially the same material with similar properties, differing only in color and pattern.

The Truth:

The term "granite" in the countertop industry often encompasses a variety of natural stone materials that can have significantly different properties. True granite is an igneous rock primarily composed of quartz and feldspar, but many stones marketed as "granite" may actually be:

• Gabbro
• Diorite
• Gneiss
• Basalt
• Other metamorphic or igneous rocks

These variations mean that different "granite" countertops can have significant differences in:

• Hardness and durability
• Porosity and stain resistance
• Mineral composition
• Maintenance requirements

Some stones sold as granite may be more porous or softer than true granite, requiring more frequent sealing and gentler care. This is why it's important to understand the specific characteristics of your particular stone and follow care recommendations tailored to it.

Conclusion

Granite countertops are an excellent investment for any home, offering beauty, durability, and value. By understanding the truth behind these common myths, you can ensure your granite surfaces remain stunning for generations.
