Stone Cleaning That Reveals—and Protects—Natural Beauty
Professional cleaning and protection for flagstone, limestone, bluestone, sandstone, slate, travertine, stone patios, walkways, walls, steps, pool surrounds, and landscape features.
Natural Stone Deserves More Than A One-Method Cleaning
Every stone surface has its own density, porosity, finish, age, joint material, staining, and previous treatment.
Ohio Power Washing begins by evaluating the stone and any existing coating or sealer. We then select a cleaning approach appropriate for that surface instead of assuming every patio, wall, or walkway should be cleaned like concrete.
- Remove accumulated soil, algae, moss, and organic discoloration
- Address surface staining with material-appropriate treatment
- Respect delicate, porous, or weathered stone
- Evaluate old coatings and sealers before application
- Recommend cleaning-only or Clean + Protect service
Care For A Wide Range Of Exterior Stone
Correct identification matters because cleaning solutions, pressure, dwell time, and sealer compatibility can vary significantly.
Flagstone
Irregular patios, paths, steps, and landscape installations.
Limestone
Porous architectural stone, walls, caps, walks, and patios.
Bluestone
Natural cleft patios, walkways, porches, and outdoor rooms.
Sandstone
Warm-toned, absorbent paving and landscape features.
Slate
Layered stone requiring careful cleaning and product selection.
Travertine
Patios and pool surrounds with unique pores and finish needs.
Stone Walls
Veneer, retaining walls, monuments, boulders, and accents.
Other Natural Stone
Evaluated individually for composition, condition, and finish.
A Careful Plan From Inspection To Final Review
The best-looking result begins with understanding the surface before applying water, cleaner, or sealer.
Identify & Inspect
We review the stone type, joints, finish, drainage, stains, damage, and previous coatings.
Protect The Area
Nearby plants, siding, glass, metal, painted surfaces, and furnishings are considered before work.
Test & Clean
We select appropriate chemistry and controlled cleaning methods for the material and condition.
Rinse & Dry
Residue is thoroughly removed and the stone is allowed the required drying time before protection.
Protect & Review
If selected, a compatible sealer is applied before final inspection and care instructions.
Three Stages Of Professional Stone Care
Cleaning reveals the surface. Preparation makes protection possible. A compatible sealer helps preserve the finished result.
Stone-Specific Cleaning
We loosen and remove grime and organic growth using an approach selected for the stone—not a universal pressure setting.
Surface Evaluation
After cleaning, we evaluate absorption, remaining stains, joints, coating residue, dryness, and sealer suitability.
Compatible Protection
When appropriate, a penetrating or surface-enhancing stone sealer is applied under suitable weather and moisture conditions.
Stone Clean Or Stone Clean + Protect
We can refresh a weathered surface or provide a more complete cleaning and protection package.
Stone Clean

Help Reduce Absorption And Simplify Maintenance
Natural stone is often porous. The right protective treatment can help reduce how readily moisture and spills enter the surface.
- Help resist water and common outdoor staining
- Make routine maintenance more manageable
- Preserve a natural appearance or enhance color when desired
- Reduce rapid absorption into suitable porous stone
- Support a complete exterior-maintenance plan
Sealer performance and appearance vary by stone type, porosity, exposure, preparation, existing coatings, and product selected. Sealing cannot make stone maintenance-free or prevent every stain.
Designed Around The Surface—And The Property
Revived Appearance
Remove the dull film and organic discoloration hiding the stone’s natural color and variation.
Controlled Cleaning
Pressure, solution strength, dwell time, and agitation are selected for the stone and its condition.
Optional Protection
A compatible sealer can help reduce absorption and improve resistance to common outdoor exposure.
Existing-Coating Review
Old sealer, wax, topical coating, or uneven finish is considered before recommending new protection.
Improved Curb Appeal
Clean patios, walks, walls, and entry stone create a better-looking exterior throughout the property.
Clear Expectations
We explain likely results, permanent conditions, specialty stains, drying needs, and aftercare in advance.
Some Stone Conditions Need More Than Routine Cleaning
Natural variation is not always a stain.
Rust migration, mineral deposits, efflorescence, oil, paint, leaf tannins, mortar residue, etching, salt damage, failed sealer, freeze-thaw deterioration, and permanent color variation may require specialty treatment or repair.
We will explain what is realistically cleanable and whether sealing is appropriate. Cleaning and sealing improve appearance and maintenance; they do not repair cracked, spalling, loose, or structurally failed stone.

Professional care for the stone features that shape residential and commercial outdoor spaces.
What Property Owners Usually Ask
Can all natural stone be pressure washed?
No. Natural stone varies greatly in hardness, porosity, surface finish, age, and condition. Some stone tolerates controlled mechanical cleaning, while softer or deteriorated material requires lower pressure and greater reliance on suitable chemistry. We evaluate the surface first.
Do you clean limestone?
Yes. Limestone is a major part of our natural-stone service. Because it is porous and can be sensitive to harsh or acidic products, the cleaning method must be chosen carefully.
Should every stone surface be sealed?
No. Sealing depends on stone type, location, moisture movement, finish, previous products, desired appearance, and condition. We recommend sealing only when the surface and application are suitable.
Will sealer make my stone shiny or darker?
Not necessarily. Penetrating natural-look products may cause little visible change, while enhancing or topical products can deepen color or add sheen. Available options depend on the stone, previous treatments, and slip-resistance needs.
Can you remove rust, oil, efflorescence, or old sealer?
Some specialty stains and coatings can be improved, but they may require additional testing, specialty products, multiple treatments, or stripping. Permanent etching, mineral changes, and stone damage may remain visible.
How long must stone dry before sealing?
Drying time depends on the stone’s porosity, weather, shade, joint system, cleaning process, and sealer requirements. The stone must meet the selected product’s moisture and weather conditions before application.
