Quick Answer: Can You Use Bleach on Granite?

❌Avoid for Routine CleaningBleach degrades sealant with repeated use

🚫Never Use Full StrengthUndiluted bleach causes immediate finish damage

⚠️Very Occasional Spot Use OnlyHeavily diluted, well-sealed surface, thoroughly rinsed

✅Better Options ExistDish soap + water and isopropyl alcohol work safely

🧴Granite-Safe CleanerspH-neutral stone cleaners clean and preserve finish

🔬Granite Is Already AntibacterialSealed granite is highly resistant to bacteria — bleach is rarely needed

The short answer: no, you should not use bleach on granite countertops as a regular cleaner or disinfectant. Bleach is a strong oxidizer with a pH of 11–13, and that combination degrades the sealant that protects granite from stains, dulls the stone’s polished finish, and can permanently alter the color of certain granite types — particularly dark, polished, or color-enhanced slabs.

The longer answer: a very diluted bleach solution applied briefly to a well-sealed granite surface for targeted stain removal — followed by immediate and thorough rinsing — is unlikely to cause visible damage in a single use. Clorox itself says this is technically acceptable. Stone fabricators, marble specialists, and countertop professionals generally disagree, pointing out that even diluted bleach causes cumulative sealant breakdown and finish dulling over time, and that equally effective, genuinely safe alternatives exist.

The bottom line for most homeowners: there is no reason to use bleach on granite. Dish soap and water handle everyday cleaning perfectly well, 70% isopropyl alcohol disinfects without harming the finish, and dedicated granite cleaners do both. Save the bleach for surfaces it is actually designed for.

What Granite Actually Is (And Why Chemistry Matters)

Granite is an igneous rock — formed over millions of years as magma slowly cooled beneath the earth’s surface. It is composed primarily of quartz, feldspar, and mica, which is what gives each slab its unique crystalline pattern and color. As a stone formed through a chemical process, granite is sensitive to other chemicals in ways that a synthetic surface like quartz or laminate is not.

Granite Is Porous

Despite its hard, dense appearance, granite is a naturally porous material. Microscopic channels run through the stone that can absorb oils, liquids, and dyes if left unprotected. This is why all granite countertops are sealed at installation — the sealer penetrates these pores and creates a protective barrier that slows absorption of spills before they can stain.

The Sealant Is the Key

When you clean granite countertops, you are primarily cleaning the sealant — not the stone itself. The sealant is what gives polished granite its shine, what prevents stains from penetrating, and what keeps the surface food-safe and hygienic. Any cleaning product that damages the sealant is effectively damaging the granite’s protection system — and once a sealant is compromised, the stone becomes vulnerable to everything it would otherwise resist.

pH Neutrality Is Non-Negotiable

Sealants and polished granite finishes are sensitive to both highly acidic (low pH) and highly alkaline (high pH) substances. A neutral pH is 7. Anything significantly below 7 is acidic; anything significantly above 7 is alkaline. Bleach sits at pH 11–13 — highly alkaline — which is why it degrades sealants and can affect the stone’s surface finish. This same chemistry explains why vinegar (acidic, pH 2–3), lemon juice, and ammonia-based cleaners are equally problematic for granite — from the other end of the pH scale.

What Bleach Does to Granite: The 4 Damage Mechanisms

Bleach does not damage granite in a single dramatic moment the way acid does. Its effects are cumulative and chemical, becoming more visible with repeated exposure. Here are the four specific ways bleach causes harm.

🛡️Sealant Degradation

Bleach’s high alkalinity and oxidizing properties break down the chemical bonds in penetrating stone sealers. Each exposure accelerates the wear of the protective layer, forcing you to reseal sooner and leaving the stone vulnerable to staining between reseals. Over time, this is the most consequential form of damage.

✨Finish Dulling

Bleach can micro-etch the polished surface of granite, robbing it of its crisp, reflective shine. This dullness is most visible on highly polished or dark-colored granite, where streaky, chalky, or hazy patches appear after the bleach dries. This type of damage is very difficult to reverse without professional grinding and refinishing.

🎨Color Change & Staining

Bleach can discolor granite — either by lifting the stone’s natural pigmentation or by reacting with color-enhancing sealers used on darker stone varieties. In some cases bleach causes paradoxical staining: because granite is porous, bleach that is not immediately and thoroughly rinsed can be absorbed into the stone and leave behind a chemical residue that looks like a stain. Dark and highly polished granite faces the highest risk.

🔧Adjacent Surface Damage

Bleach fumes and splashes do not stay neatly on the granite. Grout between countertop tiles can discolor. Nearby wood finishes, cabinet paint, and metal fixtures — faucets, hardware, sinks — can be corroded or stained. In small, poorly ventilated kitchens, even brief bleach use produces irritating fumes that linger.

⚠️ Never Mix Bleach With Other Cleaners on Granite

Bleach should never be used immediately after — or combined with — acidic cleaners (vinegar, lemon-based products, descalers), ammonia-based cleaners (Windex, many glass cleaners), or hydrogen peroxide. Mixing bleach with acids releases chlorine gas. Mixing bleach with ammonia produces chloramine vapors. Both are toxic. If you have recently cleaned your granite with any other product, do not apply bleach until the surface has been thoroughly rinsed and dried.

The Clorox Question: Why Conflicting Advice Exists

If you search whether bleach is safe on granite, you will find two seemingly contradictory positions from credible sources — and understanding why they differ helps you make a better decision.

Clorox’s position: Clorox states on its own website that Clorox Disinfecting Bleach is safe for sealed granite countertops when diluted to ⅓ cup per gallon of water, applied and left for 6 minutes, then rinsed thoroughly. Their guidance explicitly states it should never be used full strength.

Stone professionals’ position: Marble.com — a stone fabrication and care authority — calls bleach “one of the worst options” for granite, noting it causes extreme staining and accelerates sealant wear. Rock Doctor, Granite Gold, and most countertop fabricators align with this position. The consensus across the stone care industry is that bleach should be avoided entirely, because safer alternatives accomplish the same cleaning and disinfecting goals without any of the risk.

Why the gap? Clorox is speaking to a very narrow, technical scenario: a perfectly sealed surface, a heavily diluted solution, and thorough immediate rinsing. This is accurate as far as it goes — a single, properly executed bleach application under those specific conditions is unlikely to cause visible damage. The problem is that real-world use rarely meets all three conditions simultaneously. Sealants wear over time and are not always in peak condition. Many people do not rinse immediately or thoroughly enough. And “occasional” use for most people means more frequent than a stone care expert would consider safe. Stone professionals are speaking to cumulative, real-world use over months and years — and from that perspective, even cautious bleach use is a net negative compared to pH-neutral alternatives.

📌 The Practical Rule

If you are in a situation where a brief, diluted bleach wipe is genuinely unavoidable — a food safety emergency, a confirmed pathogen exposure — do it correctly: dilute heavily, limit contact time, rinse thoroughly twice, buff dry immediately with microfiber, and test your sealer the next day with the water bead test. Then reseal if needed. But for everyday cleaning and routine disinfection, use the alternatives below instead — they are safer, equally effective, and cost less per use.

Other Products You Should Never Use on Granite

Bleach is not the only problem. The list of common household cleaners that damage granite is surprisingly long, and many of them are marketed as general-purpose cleaners that seem perfectly reasonable to use on a hard countertop surface.

Product / Ingredient	pH / Type	Verdict	Why It Damages Granite
Bleach (chlorine / sodium hypochlorite)	pH 11–13 / Strong alkaline oxidizer	❌ Avoid	Degrades sealant, dulls finish, can discolor stone
Vinegar (white or apple cider)	pH 2–3 / Acidic	❌ Never Use	Etches and hazes the polished surface; strips sealant over time
Lemon juice / citrus cleaners	pH 2–3 / Acidic	❌ Never Use	Citric acid etches granite and breaks down sealer rapidly
Windex / glass cleaners	pH ~10 / Contains ammonia	❌ Avoid	Ammonia scratches the stone’s surface and causes dull, uneven finish patches
Ammonia-based cleaners	pH 11–12 / Alkaline	❌ Avoid	Ammonia is corrosive to sealant and creates surface dullness
Clorox wipes / disinfecting wipes	Variable / Contains citric acid	❌ Avoid	Contain citric acid that strips sealer even with brief contact
Formula 409 / Lysol All-Purpose	Variable / Often contains bleach or citrus	❌ Avoid	Contains bleach and/or citrus ingredients harmful to natural stone
Pledge / lemon-scented furniture products	Lemon oil content	❌ Avoid	Citrus oils etch granite and leave a film that dulls the surface
Baking soda (abrasive scrubbing)	pH 8.3 / Mildly alkaline	⚠️ Caution	Safe as a poultice ingredient; do not scrub aggressively — mild abrasion can scratch finish
Hydrogen peroxide (straight)	pH ~4.5 / Oxidizer	⚠️ Occasional Only	3% H₂O₂ is acceptable in a stain poultice mixture; do not use regularly as a surface spray
Abrasive scrub pads / steel wool	Physical abrasive	❌ Never Use	Scratches the polished surface, accumulating micro-damage that permanently dulls the finish
Comet / Ajax / scouring powders	Alkaline + abrasive	❌ Never Use	Dual damage: chemical alkalinity strips sealer while physical abrasion scratches finish

Safe Alternatives: What to Use Instead

The good news: the alternatives to bleach for granite are not obscure specialty products. They are almost certainly already in your home, they cost a fraction of what granite-specific cleaners do, and they are genuinely effective — including for disinfection.

🧼Mild Dish Soap + Warm Water

Best for: Daily cleaning, grease, fingerprints, food residue. A few drops of pH-neutral dish soap (Dawn, Ivory) in warm water is the single most versatile granite cleaner. Dish soap has mild antibacterial properties and is completely safe for sealant and finish. Use a microfiber cloth, wipe in gentle strokes, and always dry thoroughly with a second clean cloth afterward to prevent water spots and streaking. This handles 90% of everything your granite will ever encounter.

💧70% Isopropyl Alcohol

Best for: Disinfecting, killing bacteria and viruses. Isopropyl alcohol at 70% concentration is one of the safest disinfectants for granite — it kills pathogens effectively (the CDC confirms 60–90% alcohol is optimal for germ killing), evaporates quickly without leaving residue, and does not harm the sealant or finish. Spray directly onto the surface, allow 2–3 minutes dwell time, wipe with a damp cloth, and buff dry. No need to dilute — it is already formulated at the correct concentration. Do not use it as your daily cleaner; reserve it for targeted disinfection.

🏷️pH-Neutral Granite Cleaners

Best for: Daily and weekly maintenance, streak-free finish. Commercial cleaners specifically formulated for granite — Granite Gold Daily Cleaner, Method Daily Granite Cleaner, Weiman Granite Cleaner — are pH-balanced to approximately 7 and free from acids, ammonia, and bleach. Many also contain light conditioners that help maintain the stone’s finish. These are the easiest all-in-one option for homeowners who prefer a ready-to-use spray without mixing anything. Follow label instructions; typically spray on, wipe with microfiber, buff dry.

🧪DIY Granite Disinfecting Spray

Best for: Daily cleaning with added disinfecting power. Mix 4 tablespoons of isopropyl alcohol, 4 drops of dish soap, and warm water to fill a 1-liter spray bottle. This homemade solution combines the gentle cleaning power of dish soap with the disinfecting action of isopropyl alcohol, and is safe for daily use on granite. Spray on, wipe with a soft microfiber cloth, and buff dry. Store in a labeled spray bottle under the sink for convenience.

🪨Granite-Specific Spray Cleaners

Best for: Maintaining shine, weekly deeper clean. Products like Granite Gold Clean & Shine or Weiman Granite Polish combine cleaning and light polishing in one application. These are particularly useful for maintaining the surface between annual or biannual resealings. Use as a supplement to daily dish soap cleaning, not as a replacement — these polishing sprays are not designed to clean heavy grease or food buildup.

💧Plain Warm Water

Best for: Quick wipe-downs, low-traffic surfaces. For countertops that only encounter dry use — no food prep, minimal spills — warm water and a microfiber cloth is entirely adequate. Wipe, then buff dry. Water alone removes surface dust, light debris, and minor smudging without any chemical exposure to the sealant. This is an underrated option that most homeowners overlook in the search for a “powerful” cleaner when none is needed.

Daily Cleaning Routine for Granite Countertops

A consistent simple routine keeps granite countertops clean, hygienic, and beautiful without requiring any harsh products or special effort. The entire process takes about 3–4 minutes.

Clear the countertop and remove crumbsWipe away loose crumbs and debris with a dry microfiber cloth or your hand before introducing any liquid. This prevents debris from scratching the surface when wet wiping begins.
Wipe down with dish soap and warm waterAdd a few drops of mild, fragrance-free dish soap to a bowl or spray bottle of warm water. Dampen your microfiber cloth thoroughly, wring it out so it is not dripping, then wipe the entire countertop surface using smooth, overlapping strokes. Wring and re-dampen the cloth as needed. Pay extra attention to areas around the sink, cooktop, and where food prep happens.
Rinse with clean waterRinse the cloth with clean water (no soap) and wipe the countertop again to remove any soap residue. Soap left to dry on granite can cause a cloudy buildup film over time. This rinse step is one of the most commonly skipped — and one of the most important for maintaining a clear, bright finish.
Dry thoroughly with a clean microfiber clothNever leave granite wet. Water left to sit — especially hard water — can leave mineral deposits and staining, and standing water eventually works into even well-sealed stone at seam and edge areas. Dry and buff the surface with a clean, dry microfiber cloth. Buffing in small circular motions as you dry helps restore the stone’s natural shine without any additional product.
Disinfect as needed (not necessarily daily)After raw meat preparation or when explicit disinfection is needed, spray 70% isopropyl alcohol onto the surface, allow it to dwell for 2–3 minutes, then wipe with a damp cloth and dry. Well-sealed granite is already highly resistant to bacterial growth in normal use — the dish soap cleaning routine in steps 1–4 is adequate for daily hygiene. Reserve the alcohol spray for situations where pathogen reduction is specifically warranted.

✅ One Easy Daily Habit: Blot, Don’t Wipe

When a spill happens, blot it immediately with a paper towel or cloth rather than wiping it across the surface. Wiping can spread the liquid — especially oils, wine, and acidic fruit juices — into additional pores and crevices. Blotting lifts the liquid directly off the surface without spreading it. This single habit prevents the majority of stains that homeowners mistakenly attribute to inadequate sealing.

Removing Stains Without Bleach

The temptation to reach for bleach is strongest when a visible stain appears on granite — and this is precisely when the bleach urge is most understandable and most worth resisting. The good news: most granite stains respond well to a poultice treatment that is far more effective than bleach for the specific stain chemistry involved, without any of the sealant damage.

What Is a Poultice?

A poultice is a thick paste applied over a stain that draws the staining substance out of the pores of the stone as it dries, rather than trying to dissolve the stain chemically. It is the method recommended by stone professionals for virtually all granite stain types, and it works on stains that have already penetrated below the sealer — something bleach cannot effectively address.

🧪 Granite Stain Poultice Guide — By Stain Type

Stain Type	Poultice Formula	Application & Timing
Oil-based Cooking oil, butter, grease, hand lotion	Baking soda + water (peanut butter consistency)	Apply thick layer, cover with plastic wrap, tape edges, pierce a few holes. Leave 24–48 hours. Remove, rinse, dry. Repeat if needed.
Organic Coffee, tea, wine, berries, food coloring	Baking soda + 3% hydrogen peroxide (peanut butter consistency)	Same application as above. 24–48 hours. The hydrogen peroxide oxidizes the organic pigment gently without damaging the stone.
Ink / dye Marker, pen, food dye	Acetone (nail polish remover) on a cotton ball — dab gently, do not wipe	Dab, blot, repeat. Do not rub. Rinse well. Use acetone sparingly and ventilate the area — fumes are strong.
Water spots / mineral deposits Hard water rings, calcium buildup	Fine 0000 steel wool (dry) — very light circular buffing only	Dry buff only on polished granite. Do not use on honed or leathered finishes. Follow with a granite sealer to protect the area.
Fresh spills (any type) Still wet or less than 1 hour old	Blot immediately with paper towel, then clean with dish soap + warm water	Speed is the most effective stain treatment. Most spills cause no permanent staining if addressed within minutes on well-sealed granite.

📌 Bleach Will Not Remove Set-In Granite Stains

Bleach is an oxidizer and disinfectant — it is effective at killing microorganisms on surfaces, but it does not draw staining agents out of porous stone the way a poultice does. Applying bleach to a set-in oil or organic stain on granite is likely to partially bleach the area around the stain, making it look worse, while the original staining material remains in the stone’s pores. Poultice treatment is the correct method for stain removal — and it works on stains that have been in the stone for weeks or even months.

The Real Protection: Sealing Your Granite

The single most important thing you can do for granite countertops — more important than any specific cleaner choice — is maintaining an effective seal. A well-sealed granite surface is highly resistant to bacteria, stains, and chemical exposure. A poorly sealed or unsealed granite surface is vulnerable to all three, regardless of how carefully you clean it.

The Water Bead Test

You can check your granite’s seal integrity at any time with a simple test that takes less than a minute.

💧 Water Bead Seal Test

✅ Seal Is Intact Water droplets bead up on the surface and sit visibly rounded for several minutes without spreading or soaking in. Your sealer is working correctly — no immediate resealing needed.
❌ Reseal Needed Water spreads flat or is absorbed within a few minutes, leaving a darkened wet patch. Your sealant has worn through in this area — reseal promptly to restore protection.

Test in multiple locations — around the sink, near the cooktop, and in the center of the counter. High-use zones wear through sealant faster than lower-traffic areas.

How Often to Reseal

For most kitchen granite countertops, resealing every 1–2 years is appropriate. High-traffic surfaces, lighter-colored granite (which tends to be more porous), and countertops exposed to more cooking oils and acidic spills may need resealing annually. Darker granite is often denser and may only need sealing every 3 years. Performing the water bead test annually is more reliable than following a fixed calendar schedule, since actual wear depends on how heavily the surface is used and which products have been used on it.

How to Reseal

Clean the countertop thoroughlyUse dish soap and water to remove all surface grease, residue, and cleaner buildup. Allow the surface to dry completely — at least 30–60 minutes after cleaning — before applying sealer. Sealers cannot penetrate into wet stone.
Apply sealer in 3-foot sectionsSpray or apply the granite sealer product (Granite Gold Sealer, StoneTech BulletProof Sealer, and Method Stone Care are widely recommended) in a manageable section. Immediately wipe the sealer into the stone with a clean microfiber cloth — do not allow it to puddle or dry before wiping.
Buff until dryUse a second clean cloth to buff the area dry and clear of any haze. Move to the next 3-foot section and repeat. Overlap slightly between sections to avoid gaps in coverage.
Apply 2–3 coatsFor maximum protection, apply two or three coats, allowing 20–30 minutes between each coat. The additional layers fill deeper pores that the first coat may not have fully penetrated. This is especially important for lighter, more porous granite varieties.
Allow full cure time before heavy useMost sealers are fully cured within 24 hours, though the surface may be usable sooner. Avoid placing wet objects directly on the counter and avoid heavy cleaning for at least 24 hours after resealing to allow the sealer to fully bond with the stone.

Frequently Asked Questions

I accidentally used bleach on my granite — what should I do?

Act immediately. Rinse the area thoroughly with clean water — twice — then dry it completely with a microfiber cloth. Inspect the surface for any dullness, streaking, or discoloration once dry. If the bleach was diluted and you rinsed quickly, a single exposure is unlikely to cause permanent visible damage on a well-sealed surface. Perform the water bead test the next day to check whether the sealant has been compromised — if water no longer beads up in that area, reseal promptly. If you notice a dull patch, a stone restoration professional can polish and refinish the affected area.

Is it safe to use Clorox wipes on granite?

No — and this is one of the most common mistakes homeowners make. Despite Clorox’s statement that diluted bleach solution is technically safe on sealed granite, Clorox wipes are a completely different product. Clorox wipes contain citric acid in addition to other active ingredients, and citric acid is specifically harmful to granite sealants and polished stone surfaces. Marble.com and most stone care professionals explicitly name Clorox wipes as a product to avoid on natural stone entirely. The contact time and citric acid content make wipes riskier than a diluted bleach solution used and rinsed correctly. Use a damp cloth with dish soap or a granite-safe spray instead.

Can I use hydrogen peroxide on granite?

3% hydrogen peroxide (the standard drugstore concentration) is acceptable as an occasional spot treatment and as a poultice ingredient for organic stains like coffee, wine, and berries. It is a gentler oxidizer than bleach and is far less likely to damage sealant in limited use. However, it should not be used as a routine daily cleaner or disinfectant spray — repeated use can gradually dull the finish and dry out the sealant over time. Concentrated hydrogen peroxide (above 3%) should never be used on granite. For routine disinfection, 70% isopropyl alcohol is a better choice — it is equally effective at killing pathogens, evaporates cleanly without residue, and is safer for the stone’s long-term appearance.

Why does my granite look dull and cloudy even though I clean it regularly?

Cloudy or dull granite is almost always caused by residue buildup — soap, cleaning products, or sealer that was not fully rinsed and buffed dry, accumulating into a film over multiple cleaning sessions. This is not permanent damage in most cases. Start by cleaning thoroughly with dish soap and warm water, rinsing completely, and drying aggressively with a clean microfiber cloth. If cloudiness persists, apply a small amount of mineral spirits to a soft cloth and wipe the affected area — this dissolves most surface residues effectively. For stubborn haze, very light dry buffing with 0000 (extra-fine) steel wool in circular motions can restore clarity. Follow any of these treatments by applying a fresh coat of granite sealer to the area. If cloudiness continues after all these steps, it may indicate that previous exposure to bleach, ammonia, or acidic cleaners has caused actual surface etching, which requires professional grinding and refinishing.

Is granite really antibacterial? Do I actually need to disinfect it?

Sealed granite is among the most bacteria-resistant countertop surfaces available. As a non-organic, non-porous (when sealed) material, it does not provide the moisture retention or surface texture that bacteria and mold require to proliferate. A University of Michigan study found that bacteria placed on sealed granite surfaces did not reproduce and died off rapidly. For everyday kitchen use, routine cleaning with mild dish soap and warm water — which removes the biofilm bacteria cling to — is entirely adequate for food safety. The main scenario where active disinfection is warranted is after handling raw poultry, meat, or fish, where pathogens like Salmonella and E. coli are specifically present in high concentrations. In those situations, 70% isopropyl alcohol after cleaning is a safe and effective disinfectant that does not require bleach.

Can I use vinegar to clean granite if I dilute it enough?

No — dilution does not make vinegar safe for granite. Vinegar’s acidity (pH 2–3) etches the polished surface of granite and breaks down stone sealers regardless of concentration. Even highly diluted vinegar, used repeatedly, causes cumulative etching that manifests as a dull, hazy finish over time. The same applies to any citrus-based cleaner, lemon juice, and acidic “natural” cleaning products. Granite requires pH-neutral cleaners — anything significantly below pH 7 (acidic) or above pH 7 (alkaline) creates problems. Dish soap, which is close to pH-neutral, is the correct everyday choice, not vinegar.

How can I tell if my granite is sealed well enough for daily use?

Use the water bead test described in this article — it takes 60 seconds and gives you an immediate, reliable answer about your specific countertop’s current seal condition. Sprinkle a few drops of water on the surface and watch. If water beads up and stays rounded, the seal is intact. If water spreads and soaks in within a few minutes, leaving a darker wet area, the seal has worn through and resealing is needed. Test in multiple locations — around the sink and faucet area, where sealant wears fastest due to constant water exposure, and near the cooktop, where cooking oils and heat accelerate wear. When in doubt, resealing costs very little in time and material and provides significant protection — there is no downside to resealing more frequently than strictly necessary.

What is the absolute safest daily cleaning routine for granite?

The simplest and safest daily routine: wipe down with a damp microfiber cloth dampened with warm water and a few drops of mild dish soap, wipe again with a clean damp cloth to rinse off soap residue, then dry completely with a dry microfiber cloth and buff lightly for shine. That is it. No specialty products, no mixing, no risk. For weekly deeper cleaning, use a pH-neutral granite-specific cleaner. For periodic disinfection, use 70% isopropyl alcohol after cleaning. Once a year, perform the water bead test and reseal if needed. This routine keeps granite looking great indefinitely and costs almost nothing.

🪨 Can You Use Bleach on Granite? — Key Takeaways

Short answer: No. Bleach degrades granite sealant, dulls the polished finish, and can permanently discolor stone — especially dark or highly polished varieties.
The one narrow exception: A heavily diluted solution on a well-sealed surface for very occasional spot treatment, immediately and thoroughly rinsed — technically not harmful in a single use, but unnecessary when safer alternatives exist.
Never use: Full-strength bleach, Clorox wipes, vinegar, lemon-based cleaners, ammonia, Windex, Formula 409, abrasive scrubbers, or scouring powders on granite.
Daily cleaning: Mild dish soap + warm water + microfiber cloth. Rinse completely and dry immediately. This handles 90% of daily cleaning needs.
Disinfecting: 70% isopropyl alcohol — spray on, 2–3 minute dwell, wipe with damp cloth, buff dry. No bleach needed.
Stain removal: Baking soda + water poultice for oil stains; baking soda + 3% hydrogen peroxide poultice for organic stains (coffee, wine). Leave 24–48 hours covered with plastic wrap.
The real protection: A well-maintained sealant. Test with the water bead test annually and reseal when water no longer beads up on the surface.
Cloudy granite: Almost always residue buildup — deep clean with dish soap, rinse completely, buff dry. Use mineral spirits for persistent haze.
