Why Travertine Requires Special Care
What Is Travertine?
Travertine is a natural limestone that’s commonly used in showers, floors, and walls for its elegant and timeless appearance. However, its porous structure makes it vulnerable to mold, mildew, and water stains, especially in damp areas like showers.
Common Mistakes When Cleaning Travertine
- Never use vinegar or bleach: These acidic or harsh cleaners can etch and discolor the stone
- Avoid abrasive scrubbers: Steel wool or stiff brushes can scratch the finish
- Don’t skip sealing: Unsealed travertine absorbs moisture more easily, encouraging mold regrowth

Step-by-Step: How to Clean Mold Off Travertine Showers
Step 1 – Dry the Area First
Before starting, ensure the shower area is completely dry. Use a fan or open a window to ventilate. Mold thrives in damp environments, so drying the space slows its spread.
Step 2 – Apply a pH-Neutral Cleaner
Spray your stone-safe cleaner directly on the moldy sections of your shower. Let it sit for 5–10 minutes. This will help loosen the mold without damaging the stone’s surface.
Step 3 – Scrub Gently
Using a soft-bristle brush or non-abrasive sponge, scrub the mold in small circular motions. Focus on grout lines and etched areas where mold hides. Avoid using pressure that could scratch the surface.
Step 4 – Rinse the Surface Thoroughly
Use clean, warm water and a microfiber cloth to rinse away the cleaner and mold residue. Leaving residue behind can cause streaks or attract more buildup.
Step 5 – Spot Treat With Hydrogen Peroxide
For stubborn mold spots that don’t come off, dampen a cotton ball or cloth with 3% hydrogen peroxide and dab directly onto the affected area. Let it sit for 10–15 minutes. Rinse thoroughly.
Note: Hydrogen peroxide is safer than bleach and won’t damage sealed travertine when used correctly.
Step 6 – Dry the Area Completely
After cleaning, dry the area fully using a fresh microfiber towel. Travertine must be kept dry to prevent future mold growth.
How to Prevent Mold on Travertine in the Future
1. Keep the Area Well-Ventilated
Use an exhaust fan during and after showers. Open the door or window to allow air to circulate and moisture to escape. Less humidity = less mold.
2. Wipe Down the Shower After Use
A quick daily wipe with a microfiber cloth can make a huge difference. This prevents moisture and soap scum from building up in textured stone.
3. Seal the Travertine Regularly
Apply a breathable stone sealer every 6 to 12 months. This creates a barrier that makes it harder for water and mold to seep into the surface.
