pH-safe cleaning is essential for terracotta floors because terracotta is a porous, natural clay material that can be easily damaged by harsh chemicals. Cleaners that are too acidic (like vinegar) or too alkaline (like bleach or ammonia) can strip sealants, cause discoloration, and slowly erode the surface. Using a pH-neutral cleaner helps preserve the floor’s natural color and texture while protecting any existing sealant. These cleaners are gentle enough to clean effectively without reacting chemically with the clay.
To clean terracotta floors safely, sweep or vacuum first to remove grit that could scratch the surface, then mop with warm water mixed with a pH-neutral floor cleaner. Avoid soaking the floor, as excess water can seep into the porous tiles and cause stains or damage over time. After mopping, rinse lightly with clean water if recommended by the cleaner, and dry the floor to prevent water marks. Regular pH-safe cleaning keeps terracotta floors looking warm and natural while extending their lifespan.
What Are Terracotta Floors?
Terracotta floors are made from natural clay that is shaped and fired at relatively low temperatures, giving them warm tones and a rustic appearance. Because they are usually unglazed, terracotta tiles are highly porous and require proper sealing and maintenance in commercial environments.
Types of Terracotta Floors
Terracotta flooring comes in several types, each suitable for different commercial applications depending on traffic, aesthetics, and maintenance needs:
Unglazed Terracotta
- Natural, matte finish with earthy tones.
- Highly porous, so it requires sealing to prevent stains.
- Ideal for rustic restaurants, cafes, or heritage-style commercial spaces.
Glazed Terracotta
- Has a protective glossy layer that reduces porosity.
- Easier to clean and more resistant to spills, making it suitable for hotels, retail stores, and lobbies.
Pressed or Machine-Made Terracotta
- Uniform in size and thickness, offering a consistent look.
- Often used in large commercial areas like courtyards, entryways, and warehouses.
Handmade Terracotta
- Each tile is unique, with natural variations in color and texture.
- Perfect for boutique hotels, heritage buildings, and premium commercial interiors where aesthetics are a priority..
Why Proper Cleaning Matters for Terracotta Floors
Terracotta floors may look durable, but their porous nature makes them vulnerable to damage if cleaned incorrectly. In commercial environments, using harsh chemicals, acidic cleaners, or excessive water can penetrate the tile surface, causing discoloration, staining, and long-term structural weakening. Proper cleaning protects both appearance and safety.

Common Causes of Dirt and Staining on Terracotta Floors
Terracotta floors gradually accumulate grime and stains, particularly in commercial environments with constant foot traffic. Because terracotta is porous, contaminants can penetrate the surface if cleaning and sealing are not properly maintained.
Foot Traffic Carrying Dirt, Sand, and Moisture
In commercial spaces, shoes bring in abrasive dirt and moisture from outdoors. These particles scratch the surface and allow grime to settle deep into the tile.
Food Spills, Oils, and Grease
Restaurants, cafés, and hospitality venues often experience food and oil spills. These substances absorb quickly into unsealed terracotta, causing dark stains and odors.
Outdoor Exposure in Courtyards or Entrances
Terracotta used in outdoor or semi-outdoor areas is exposed to rain, dust, and environmental pollutants. Continuous exposure increases moisture absorption and surface discoloration.
Inadequate Sealing or Worn Sealers
When sealers wear down or are applied incorrectly, terracotta tiles lose their protective barrier. This allows dirt, liquids, and oils to penetrate the surface more easily.
Use of Incorrect Cleaning Products
Acidic or harsh cleaners can strip sealers and damage the tile surface. This leaves terracotta vulnerable to staining and accelerates surface deterioration.
How to Clean Terracotta Floors Properly
Daily and Routine Cleaning
Daily maintenance is essential for commercial terracotta floors. Sweeping or dust mopping removes loose dirt and grit that can scratch the surface and wear down sealers. Microfiber dust mops are ideal, as they trap fine particles without abrasion.
Damp Mopping With pH-Neutral Cleaners
For routine cleaning, use a pH-neutral terracotta-safe cleaner mixed with warm water. Mop with a lightly damp mop—never oversaturate the floor. Excess moisture can seep into unsealed areas and weaken the tile over time.
Allow floors to dry completely after cleaning to prevent moisture absorption.
Deep Cleaning for Heavily Soiled Floors
In commercial spaces with heavy soil buildup, deep cleaning may be required. Apply a terracotta-safe cleaner and allow it to dwell briefly to loosen embedded dirt. Gently scrub using a soft-bristle brush or low-speed floor machine with non-abrasive pads, then rinse thoroughly and dry.
Safe Stain and Spill Removal for Terracotta Floors
Immediate Spill Cleanup
Spills should be cleaned immediately to prevent liquids from soaking into the porous surface. Prompt action reduces staining and slip hazards in commercial environments.
Use pH-Neutral Cleaning Solutions
Mild, pH-neutral cleaners are effective for removing food spills, oils, and dirt without harming the tile or sealer.
Avoid Harsh or Acidic Products
Vinegar, bleach, ammonia, and citrus-based cleaners should be avoided, as they can etch the surface and strip protective sealers—consistent with warnings for natural porous tiles from sources like Consumer Reports flooring care guides.
The Importance of Sealing Terracotta Floors
Sealing is one of the most critical steps in terracotta floor care, especially for commercial properties. Sealers create a protective barrier that limits moisture absorption and staining.
