Granite Countertop & Floor Care: The Complete Maintenance Guide
Granite is the most durable natural countertop stone, but it still needs proper care. Learn professional techniques to keep your granite looking stunning for decades.
Granite is the workhorse of natural stone—harder than marble, more resistant to scratching and etching, and available in a breathtaking range of colors and patterns. But 'durable' doesn't mean 'indestructible.' Granite can still stain, develop dull spots from abrasive cleaners, and lose its luster over time without proper maintenance. At Granite Heroes, we've restored and maintained granite surfaces across Chicagoland since our founding, backed by experience dating to our founding. This guide shares the same care protocols we recommend to our clients.
1. Daily cleaning with pH-neutral stone cleaner
Wipe granite surfaces daily with a pH-neutral stone cleaner and a soft microfiber cloth. While granite is more acid-resistant than marble, acidic cleaners can still dull the polished surface over time and degrade the sealer. Avoid dish soap—it leaves a film that builds up and creates a hazy, streaky appearance. Spray the cleaner, wipe, and buff dry for a streak-free shine.
Professional tip: Keep a dedicated spray bottle of stone cleaner under the kitchen sink for quick daily wipe-downs. Consistency is the key to granite that always looks freshly polished.
2. Seal granite every 1–2 years
Most granites benefit from an impregnating sealer applied every 1–2 years. The sealer fills the stone's microscopic pores, creating a barrier against stain-causing liquids. Apply a thin, even coat with a clean cloth, let it absorb for 15–20 minutes, then buff off residue. Some very dense granites (like Absolute Black or Uba Tuba) may not absorb sealer at all—this means they're naturally non-porous and don't need sealing.
Professional tip: Do the water test: place a tablespoon of water on the granite. If it beads and stays on the surface after 10 minutes, the seal is fine. If it absorbs and darkens the stone, it's time to reseal.
3. Remove stains with the right poultice
For oil-based stains (cooking oil, grease), create a poultice with baking soda and acetone. For organic stains (coffee, wine, juice), use baking soda and hydrogen peroxide. For water stains and rings, often simple re-polishing or a light buff with 0000 steel wool works. Apply the poultice ¼-inch thick, cover with plastic wrap, and leave 24–48 hours.
Professional tip: Identify the stain type before treating—using the wrong poultice formula can be ineffective or even set the stain deeper.
4. Repair chips and fissures professionally
Granite can chip from impact (dropping a heavy pot or pan) and may have natural fissures that open over time. Small chips can be filled with a color-matched epoxy that's cured under UV light for an invisible repair. Natural fissures (different from cracks—they follow the stone's crystalline structure) are normal and usually don't require treatment unless they catch dirt or liquids.
Professional tip: Don't confuse fissures with cracks. Fissures are part of granite's natural beauty and rarely compromise structural integrity. A professional can tell the difference.
5. Protect from heat and impact damage
While granite is more heat-resistant than marble, repeated thermal shock (placing a 500°F pan directly from the oven onto cold granite) can cause hairline cracks over time. Always use trivets for hot cookware. Similarly, avoid placing heavy objects on the edge or overhang of granite countertops—granite is strong in compression but brittle under point loads.
Professional tip: The most common granite damage we see is chips from dropping cast-iron skillets or ceramic dishes onto countertop edges. A simple rubber mat near the cooktop prevents most incidents.
6. Professional polishing restores the factory finish
Over time, even well-maintained granite develops micro-scratches and dull spots from daily use. Professional diamond polishing restores the factory-level shine in a few hours. Unlike marble, granite rarely needs full honing—a light polish with fine diamond pads (800–3000 grit) is usually sufficient. At Granite Heroes, our granite polishing service includes cleaning, polishing, and premium sealer application.
Professional tip: Schedule professional granite polishing every 5–10 years, or sooner if you notice visible dullness or scratching patterns.
Can I use Clorox wipes on granite?
We don't recommend it. Clorox wipes contain citric acid and other chemicals that can gradually degrade the sealer and dull the polished surface. Use a dedicated pH-neutral stone cleaner for safe, effective daily cleaning.
Does all granite need to be sealed?
No. Some very dense, dark granites (Absolute Black, Uba Tuba, Star Galaxy) are naturally non-porous and don't absorb sealer. The water test will tell you: if water beads on the surface after 10 minutes, sealing isn't needed.
How do I remove hard water stains from granite?
Hard water deposits on granite can usually be removed with a stone-safe hard water remover or a paste of baking soda and water. For stubborn deposits, a light buff with 0000 steel wool (super fine) followed by resealing works well. Never use CLR or Lime-Away on natural stone.
Can cracked granite be repaired?
Yes, most granite cracks can be repaired with color-matched epoxy that's virtually invisible after curing. The repair is often stronger than the original stone. Full replacement is only necessary for structural damage spanning the entire slab.
How much does granite countertop restoration cost in Chicago?
