Understanding Natural Stone
Natural stone—especially calcite-based stones like marble, travertine, limestone, and some slates—has a sensitive chemical makeup. Cleaning products not designed specifically for stone can cause permanent surface damage. Once you understand what to use (and what to avoid), maintenance becomes straightforward and predictable.
Routine Preventative Measures
Simple habits can dramatically extend the life of your stone:
Use coasters under glasses, especially those containing citrus or alcohol.
Avoid placing hot cookware directly on stone—use trivets or mats.
Use placemats under dishes or décor that could scratch the surface.
Never use glass cleaner, multipurpose cleaner, bleach, or toilet bowl cleaner on natural stone.
Only use products clearly labeled as natural-stone safe.
Treating Spills Correctly
Acidic or caustic liquids can etch polished marble, limestone, travertine, and many slates. Etching is surface corrosion, not a stain.
DO:
Blot spills immediately.
Use stone-safe cleaners only.
DON’T:
Rub spills—this spreads the damage.
Use glass cleaner near marble vanities or toilet bowl cleaner on stone floors.
Note: Cultured marble is man-made and behaves differently from natural marble.
Caring for Natural Stone Floors
Choose the right cleaning tools
For routine cleaning, invest in:
A quality microfiber mop (ideal for polished stone)
A proper dual-bucket wringer system
Clean cotton towels or microfiber cloths
A squeegee for small spills or detailing
Avoid sponge mops—they leave streaks and can push dirt into stone pores.
Newly Installed Stone Floors
Brand-new polished stone should be professionally detailed to remove:
Grout haze
Construction residue
Adhesive films
Factory blemishes
This deep-cleaning opens the stone’s pores and prepares it for sealing (if appropriate).
If grout film remains, a stone-safe film remover may be necessary.
Should Newly Installed Floors Be Sealed?
Porous stones (honed limestone, travertine, some granites): sealing is recommended.
Highly polished marble or dense granites: sealing is usually not needed.
If you skip professional detailing after installation:
Avoid damp-mopping for several days.
Vacuum gently with a canister vacuum (not an upright).
Use only horsehair brush attachments.
Dry dust-mop frequently with a clean microfiber pad.
Avoid stone soaps—they leave residue and require periodic stripping. Use a pH-neutral cleaner formulated specifically for natural stone.
Deep Cleaning Floors
When needed, use a stone-safe heavy-duty tile and grout cleaner. Homes with direct outdoor access should also use quality floor mats—clean them regularly to prevent grit from damaging polished stone.
Kitchen, Bath & Vanity Care
Kitchen Countertops
Even durable stones like granite should not be cleaned with:
Glass cleaner
Dish soap
Generic household cleaners
They can damage the sealer or leave a soapy film.
Use a stone-safe cleaner—full strength in cooking zones, diluted 1:1 on light-use areas. Always blot spills rather than rub them.
Avoid scouring pads with abrasive grits. Use only plastic-safe alternatives.
Vanity Tops
Clean regularly with a diluted stone-safe cleaner.
Avoid glass cleaner overspray on marble vanities—use the same stone-safe cleaner or rubbing alcohol for mirrors.
Keep perfumes, lotions, and cosmetics on protected trays.
Never use powder cleansers or cream abrasives.
Shower Stalls: Dos & Don’ts
DO:
Monitor grout and caulk lines.
Clean daily using diluted stone cleaner and a squeegee.
DON’T:
Use powdered or cream cleansers.
Use common soap scum removers (e.g., Tilex) on polished stone.
Use mildew removers or harsh disinfectants not labeled stone-safe.
Use “self-cleaning” spray products.
Removing soap scum:
Use only stone-safe soap film removers.
Treating mildew:
Use a stone-safe mildew remover (e.g., MB-9).
Cleaning Around Toilets
If your toilet sits on marble or another natural stone, never use generic toilet bowl cleaners—they can etch the stone instantly. Use powder cleansers for the bowl and stone-safe disinfectants around the base.
Common Questions About Sealing Stone
How many applications of sealer are needed?
Depends on porosity—granite often needs 2–3 applications; very porous stones may need more.
How often should resealing be done?
Generally every 2–5 years, depending on exposure to heat, sunlight, and foot traffic.
How can I tell if resealing is needed?
Place a few drops of water on the stone. If the area darkens within 30 minutes, the stone needs resealing.
Will sealing change the appearance?
Most impregnating sealers do not alter the finish. They work below the surface to reduce absorbency.
Will sealing prevent etching?
No. Etching is a chemical reaction, not absorption—sealants cannot prevent it.
What does a color-enhancing sealer do?
Enhancers deepen color and can create a wet look while offering stain protection.
Should grout be sealed?
Yes—sealing grout prevents staining and simplifies routine cleaning. Color sealing can also change or refresh grout color.
Stain Management
Not all discoloration is a stain.
A true stain is darker than the stone and caused by absorption (oil, coffee, ink).
Lighter marks are usually etching (acid damage) or bleaching (alkali damage).
Etching looks like water marks or rings and occurs on calcite-based stones. It requires professional honing—poultices will not fix it.
10 Common Stone Problems
Loss of shine from wear—can be restored professionally.
Etching from acidic spills—requires honing or polishing.
Stains from oils, inks, or foods—many removable, some permanent.
Efflorescence—white powder from moisture; resolves as the stone dries.
Spalling/flaking—internal salt buildup; difficult to repair.
Yellowing—from dirt, waxes, or iron oxidation.
Lippage—uneven tiles; requires grinding to flatten.
Cracks & chips—repairable with custom-tinted epoxy.
White stun marks—internal crystal fractures; often unrepairable.
Water rings/spots—etching or mineral deposits; requires honing.
Professional Maintenance Services
Routine maintenance keeps stone looking its best long-term. Superior Stone Refinishing offers customized maintenance plans, ongoing cleaning, periodic sealing, and full restoration. Call 714-917-5255 to learn more.
Stone Restoration Services
Stone restoration involves returning worn, scratched, or etched stone to its original—or newly desired—finish. This work must be performed by trained professionals using wet diamond grinding, honing, and polishing.
Diamond grinding produces superior clarity and lasts longer than screen sanding or polish-only methods. Though the upfront cost is higher, the extended lifespan saves money over time.
Professionals also ensure surrounding surfaces are protected from water and slurry.
Tile & Grout Cleaning and Restoration
A trained tile and grout specialist can:
Deep-clean tile and grout
Replace missing grout
Repair broken tiles
Seal grout
Color seal grout for a fresh, uniform appearance
If your tile or stone needs restoration, maintenance, or expert care, Superior Stone Refinishing is here to help.
