Granite countertops are one of the most popular and luxurious choices for kitchens, bathrooms, and even outdoor spaces. Known for their durability, heat resistance, and timeless aesthetic, granite surfaces can last for decades when properly maintained. But one of the most commonly asked questions is: how often should granite countertops be polished?
In this guide, we’ll explore how granite polishing works, what influences polishing frequency, how to recognize when it’s needed, and how polishing differs from sealing or cleaning. Whether you have natural granite or artificial granite, maintaining that signature shine is key to keeping your investment looking brand new.
What Is Granite Polishing?
Polishing is the process of smoothing and refining the surface of granite countertops to enhance their shine and remove minor scratches or dullness. Unlike cleaning or sealing, polishing affects the topmost layer of the granite slab, reviving its reflective quality and color depth.
Benefits of Granite Polishing:
- Restores shine and gloss
- Removes superficial scratches
- Highlights natural color and veining
- Enhances stain resistance when combined with sealing
Polishing is not required as frequently as cleaning or sealing, but it plays a vital role in the long-term beauty of your countertops.
Factors That Influence How Often Granite Should Be Polished
The ideal polishing frequency can vary depending on several factors:
1. Type of Granite
Darker and denser types of granite often retain their polish longer than lighter, more porous varieties.
2. Finish Type
- Polished granite maintains its shine the longest.
- Honed or leathered finishes are intentionally matte and don’t require polishing.
3. Usage Level
Kitchen countertops used daily for meal prep, cutting, and spills will need more attention than granite in a guest bathroom or bar.
4. Maintenance Routine
Granite that is cleaned and sealed regularly will stay polished longer. Neglecting basic care can lead to faster dulling.
5. Location
Granite exposed to direct sunlight (such as in outdoor kitchens) may lose its luster more quickly due to UV rays.
Recommended Polishing Schedule for Granite Countertops
While there’s no one-size-fits-all answer, a general guideline for granite polishing is:
- Every 5–10 years for residential use with regular maintenance
- Every 1–2 years for commercial or high-traffic areas
- Spot polishing as needed for minor dull areas or scratches
If your granite has started to appear cloudy, uneven, or lost its shine despite cleaning, polishing may be necessary sooner.
Signs Your Granite Needs Polishing
Look for these indicators that it’s time to polish your granite countertops:
- Dull, faded appearance
- Visible fine scratches or etching
- Uneven sheen across the surface
- Water no longer beads up on the surface (may also indicate sealing is due)
A well-maintained granite slab will retain its polish for many years, so if you’re seeing these signs, consider professional polishing or using a stone-safe DIY product.
How to Polish Granite: DIY vs. Professional
DIY Granite Polishing
You can use a commercial granite polish for light touch-ups:
- Clean the surface thoroughly.
- Apply granite polish with a microfiber cloth.
- Buff gently in circular motions.
- Repeat monthly or quarterly as needed.
Professional Polishing
For deeper scratches or long-neglected countertops, hire a stone restoration specialist. They use diamond abrasives, polishing powders, or mechanical polishers to restore the surface’s original luster.

The Role of Sealing in Polished Granite Maintenance
It’s important not to confuse polishing with sealing. While polishing enhances the granite’s look, sealing protects it from staining.
General Sealing Schedule:
- Every 1–3 years depending on usage and granite porosity
Regular sealing extends the life of your polished finish by preventing water, oil, and other contaminants from penetrating the surface.
Cleaning Tips to Maintain Polished Granite
Daily cleaning also plays a crucial role in preserving the shine of your granite:
- Use a soft cloth or sponge
- Choose pH-neutral, granite-safe cleaners
- Avoid harsh chemicals like bleach, ammonia, or vinegar
- Wipe up spills immediately to avoid etching
Polished granite is easier to clean and less likely to absorb liquids than unpolished stone, but maintenance remains key.
Granite Color and Polish Longevity
The granite slab color you choose can influence how frequently you need to polish it:
| Granite Color | Polish Longevity | Notes |
|---|---|---|
| Absolute Black | Very long-lasting | Shows smudges easily |
| Kashmir White | Moderate | May show etching faster |
| Tan Brown | Long-lasting | Hides dirt and scratches well |
| Blue Pearl | Excellent | Reflective and durable |
| Colonial Gold | Moderate | Needs regular upkeep |

Cost of Granite Polishing
DIY Kits:
- $10–$30 for polish and cloth
Professional Polishing:
- $200–$500 depending on countertop size and condition
The cost is minimal when compared to the investment and granite prices for new slab replacement.
Repair vs. Polishing: When to Call a Pro
Polishing handles superficial issues, but deeper cracks or chips require granite countertop repair.
Signs You Need Repair:
- Deep chips near edges
- Structural cracks
- Broken corners or mounting issues
Professionals can use epoxy, grinding, and resealing to restore your countertop without full replacement.
Final Thoughts
Polishing is an essential, though infrequent, part of granite maintenance that preserves the natural elegance and functionality of your kitchen countertop or vanity. Depending on usage and care, granite should be professionally polished every 5–10 years, with lighter DIY polishing in between.
By understanding the difference between cleaning, sealing, and polishing, you can maintain your granite’s brilliance and protect your investment for decades.
