Natural stone floors, from marble and granite to limestone, travertine, and slate, bring an unmistakable sense of sophistication and value to commercial spaces. They elevate lobbies, corridors, and public areas, leaving a lasting impression on visitors and employees alike.
But these surfaces are also highly sensitive. Without proper maintenance, natural stone can quickly lose their shine, develop etching or staining, and even suffer permanent damage. For property and facility managers, understanding how to care for stone correctly is essential to protecting both the look and longevity of your floors.
At DPM Surface Care, we help commercial facilities across Knoxville, Nashville, Chattanooga, and the Tri-Cities preserve and protect natural stone surfaces through customized maintenance programs and advanced cleaning technologies. Here are 7 best practices for cleaning natural stone floors without damaging them.
1. Understand the Type of Stone You Have
Not all natural stone is created equal. Each type has unique properties that determine the right cleaning methods and products.
- Marble and Limestone are calcium-based and highly susceptible to etching from acidic cleaners.
- Granite is harder and more durable but still benefits from proper pH-balanced cleaning to prevent dulling.
- Travertine is porous and requires sealing to prevent moisture and soil penetration.
- Slate has a textured surface that can trap dirt and debris, requiring more frequent maintenance.
A proper stone identification and condition assessment ensures you use the right care system from the start.
2. Avoid Harsh or Acidic Cleaners
The number one cause of damage to natural stone floors is the use of improper cleaning solutions. Acidic or high-alkaline products can etch, discolor, or dull the surface. Use only neutral pH cleaners specifically formulated for natural stone. These remove soils effectively without compromising the stone’s structure or finish. If you’re working with a janitorial team, make sure they’re trained to identify and use approved products only.
3. Implement a Daily Maintenance Routine
Keeping stone floors clean starts with consistent daily care. Dirt, sand, and moisture can quickly abrade the surface if left unchecked.
- Dust mop or vacuum daily using a non-abrasive microfiber tool.
- Spot clean spills immediately to prevent staining or etching.
- Use walk-off mats at all entrances to reduce tracked-in debris.
These simple steps prevent buildup and help maintain the stone’s natural luster between professional cleanings.
4. Schedule Periodic Deep Cleaning and Polishing
Even with regular maintenance, soil and micro-scratches will accumulate over time. Scheduling professional deep cleaning and restoration helps restore clarity, shine, and protection. At DPM Surface Care, we use specialized equipment and cleaning agents designed for natural stone. Our technicians are trained to:
- Gently deep clean and extract embedded soils
- Polish or hone surfaces to remove dullness and etching
- Reapply sealers (if needed) to protect against future damage
For most commercial facilities, quarterly or semiannual stone maintenance is ideal, depending on traffic and environmental conditions.
5. Protect with Proper Sealing
Sealing is one of the most critical and often overlooked steps in stone maintenance. A quality sealer provides a barrier against moisture, staining agents, and contaminants without altering the natural appearance of the stone. Penetrating sealers allow stone to “breathe” while locking out liquids and spills. Re-sealing intervals vary based on usage, but most commercial settings require reapplication every 1–2 years.
6. Avoid Common Mistakes
Facility teams often make well-intentioned mistakes that can shorten the life of stone floors. Watch out for:
- Over-wetting floors during mopping (can lead to water marks and efflorescence)
- Using waxes or coatings meant for VCT or vinyl flooring (they can trap dirt and dull stone)
- Neglecting grout lines, which can collect soil and bacteria and detract from appearance
Partnering with an experienced surface care provider ensures your staff follows proper protocols that preserve your investment.
7. Schedule Regular Inspections
Routine inspections allow you to address small issues before they become costly repairs. DPM Surface Care offers maintenance evaluations that identify early signs of wear, moisture damage, or chemical etching, helping you plan proactive care and stay ahead of problems.
