Granite countertops are one of the most popular choices for Atlanta-area kitchens and bathrooms — prized for their natural beauty, durability, and heat resistance. But unlike engineered quartz, granite is a natural porous stone that requires some care to keep it looking its best. The good news: granite countertop maintenance is straightforward once you understand the basics of sealing, cleaning, and stain prevention. This guide covers everything Atlanta homeowners need to know about how to care for granite countertops.
Why Granite Needs Different Care Than Quartz?
Granite is 100% natural stone — quarried, cut, and polished. Unlike engineered quartz, which is bound with polymer resins to create a non-porous surface, granite has microscopic pores that can absorb liquids if left unsealed. The trade-off is worth it for many homeowners: granite’s resin-free composition makes it extremely heat resistant, and its natural character means no two slabs are alike.
The key difference in care comes down to one word: sealing. Granite needs it; quartz doesn’t. If you’re weighing the two materials for your kitchen, our granite vs. quartz comparison covers the full picture.

Sealing Your Granite Countertops
Sealing is the single most important part of granite countertop care. It’s also one of the simplest.
Why Sealing Matters?
Granite sealer fills the stone’s microscopic pores, creating an invisible protective barrier. This prevents liquids like wine, coffee, and cooking oil from penetrating the surface and causing stains. Importantly, a good sealer doesn’t change the look or feel of your granite — it just adds protection you can’t see.
How Often to Seal?
- Most granite should be sealed once per year.
- High-use kitchen countertops may benefit from sealing every 6–8 months.
- Light-colored granites (like Alaska White or Bianco Antico) tend to be more porous and may need more frequent sealing.
- Dark granites (like Black Pearl) are typically denser and need less frequent sealing.
- The water test: drop a few tablespoons of water on the surface. If it beads up, the seal is good. If it soaks in within 5 minutes, it’s time to reseal.
How to Seal Granite (Step by Step)?
- Clean the countertop thoroughly and let it dry completely (24 hours is ideal).
- Apply granite sealer evenly with a soft cloth or applicator pad.
- Let it penetrate for 15–20 minutes (follow product directions).
- Wipe away excess sealer with a clean, dry cloth.
- Allow 24 hours before using the surface normally.
- Repeat annually or when the water test shows absorption.
Recommended Sealers
Popular options include TriSeal Impregnator, StoneTech BulletProof, and Granite Gold Sealer. Always use impregnating (penetrating) sealers — not topical coatings, which can leave a filmy residue and wear unevenly.
Daily Granite Countertop Cleaning
The daily cleaning routine for granite is refreshingly simple:
- Warm water + mild dish soap + soft cloth — this handles 95% of everyday cleanup.
- Wipe up spills promptly, especially acidic liquids (citrus juice, wine, vinegar, tomato sauce).
- Dry with a clean towel to prevent water spots.
- Avoid: bleach, ammonia, vinegar-based cleaners (acidic — can etch the surface over time), abrasive cleaners, and generic “all-purpose” sprays not formulated for stone.
- For convenience, use granite-specific cleaners like Granite Gold Daily Cleaner, Method Daily Granite, or StoneTech Revitalizer.
Removing Stains from Granite
Even with proper sealing, stains can occasionally happen. Here’s how to address the most common types:
Oil-Based Stains (Cooking Oil, Grease, Cosmetics)
Make a poultice by mixing baking soda with water to form a thick paste. Apply it to the stain, cover with plastic wrap, and tape the edges down. Leave it for 24–48 hours, then remove, rinse, and repeat if needed. The poultice draws the oil out of the stone.
Organic Stains (Coffee, Tea, Wine, Fruit)
For light-colored granite, use a poultice of baking soda and hydrogen peroxide. For dark granite, use baking soda and water instead (hydrogen peroxide can lighten dark stone). Leave for 24 hours, remove, and assess.
Water Spots and Hard Water Rings
Mix baking soda and water into a paste and gently rub with a soft cloth. For persistent hard water buildup, use a granite-safe hard water remover. Prevention is key: dry surfaces after cleaning and fix dripping faucets.
Etch Marks (Dull Spots from Acid Exposure)
Light etching can often be buffed out with granite polishing powder and a soft cloth. Deep etching may require professional honing and repolishing. Prevention: always use cutting boards when working with citrus, and wipe up acidic spills immediately.
Long-Term Granite Maintenance Tips
Beyond daily cleaning and annual sealing, these habits will keep your granite countertops looking their best for decades:
- Always use cutting boards — protects both the granite surface and your knife edges.
- Use trivets and hot pads — granite handles heat well, but extreme thermal shock (like a 500°F pan on a cold slab) can theoretically cause cracking in rare cases.
- Don’t sit or stand on countertops — granite is strong but can crack at unsupported spans, especially around sink and cooktop cutouts.
- Keep up with annual sealing — it’s the single most important granite maintenance task and takes less than 30 minutes.
- Address chips promptly — small chips can be filled with color-matched granite epoxy. Larger damage may need professional repair.
- For bathroom granite: squeegee shower surrounds to prevent soap scum buildup.
Granite Care by Color and Type
Not all granite behaves the same. Here’s a quick guide based on color:
- Light granites (Alaska White, Bianco Antico, Colonial White): More porous, seal more frequently, and stains are more visible. Extra care with red wine and coffee spills.
- Dark granites (Black Pearl, Ubatuba, Absolute Black): Denser and less porous, but water spots and fingerprints are more visible. A quick wipe-down keeps them looking sharp.
- Exotic granites (Blue Flower, African Rainbow): Follow the specific care recommendations for the stone — visit our Stone Gallery to learn about each variety we carry.

Frequently Asked Questions on Granite Countertop Care
How do I know when my granite countertops need resealing?
Use the water test: sprinkle a few tablespoons of water on the countertop surface. If the water beads up and stays on top, your seal is still working. If it soaks into the stone within 5 minutes (you’ll see the area darken), it’s time to reseal. Most granite should be tested every 6–12 months.
Can I use vinegar to clean granite countertops?
No. Vinegar is acidic and can etch the surface of granite over time, leaving dull spots. Even diluted vinegar should be avoided. Stick with pH-neutral cleaners — mild dish soap and water is the safest everyday option, or use a granite-specific cleaner like Granite Gold Daily Cleaner.
What happens if I never seal my granite?
Unsealed granite will gradually absorb liquids through its microscopic pores. This can lead to staining (especially from wine, coffee, and cooking oil), bacterial growth in the pores, and a dull or discolored appearance over time. Sealing is inexpensive, takes about 30 minutes, and is the single most important thing you can do to protect your granite.
How do I remove a stain that’s already soaked into granite?
Make a poultice: mix baking soda with water (for oil-based stains) or baking soda with hydrogen peroxide (for organic stains on light granite). Apply the paste to the stain, cover with plastic wrap, tape the edges, and leave for 24–48 hours. The poultice draws the stain out of the stone. Repeat if needed.
Is granite more high-maintenance than quartz?
Granite requires a bit more care than quartz — primarily annual sealing and being careful with acidic spills. But the daily cleaning routine is almost identical: soap, water, soft cloth. Many homeowners find the small extra effort well worth it for granite’s unmatched natural beauty and superior heat resistance.
