Travertine pavers are prized for their timeless beauty and natural texture, making them a popular choice for patios, pool decks, and outdoor walkways. Over time, however, they can develop stains, discoloration, or buildup from weather exposure and foot traffic. One question many homeowners ask is: Can you acid wash travertine pavers?
Let’s take a closer look at what acid washing does, whether it’s safe for travertine, and what you should do instead.
Understanding Acid Washing
Acid washing is a cleaning process that uses a diluted acid (commonly muriatic acid) to remove tough stains, mineral deposits, or grime from stone surfaces. It’s often used on concrete to restore its appearance.
While it can be effective for certain materials, acid washing is not recommended for travertine pavers.
Why You Shouldn’t Acid Wash Travertine
Travertine is a type of limestone — a calcium carbonate–based stone. Acid reacts strongly with calcium carbonate, causing it to etch, dissolve, and dull the surface. Even a mild acid solution can eat away at the stone’s polished or honed finish, leaving rough patches, pitting, and permanent damage.
If you acid wash travertine pavers, you might notice:
-
Loss of natural sheen or smoothness
-
White chalky residue
-
Increased porosity (making the stone more prone to stains)
-
Weakening of the surface structure
In short, acid washing can do far more harm than good.
Safe Alternatives for Cleaning Travertine Pavers
Instead of acid washing, you can safely clean your travertine using gentler methods:
1. Mild Soap and Water
Mix a few drops of pH-neutral stone cleaner or dish soap with warm water. Mop or scrub lightly with a soft-bristle brush, then rinse thoroughly.
2. Pressure Washing (with care)
Use a pressure washer on a low to medium setting to remove dirt, algae, and grime. Avoid using too much pressure, which could loosen the stone or grout.
3. Poultice for Stains
For stubborn stains, apply a poultice made from baking soda and water. Let it sit overnight, then rinse and wipe clean.
4. Professional Stone Cleaner
Look for products labeled “safe for natural stone.” These are specifically formulated to lift dirt and stains without damaging the stone.
Maintaining and Protecting Travertine
To keep your travertine pavers looking their best:
-
Seal them regularly (every 2–3 years) to protect against moisture and stains.
-
Sweep and rinse regularly to prevent buildup.
-
Avoid harsh chemicals, vinegar, or acidic cleaners.
Proper maintenance keeps the stone’s color rich and the surface smooth for years.
Final Thoughts
No — you should not acid wash travertine pavers. The acid will damage the stone, strip its finish, and make it more vulnerable to staining. Instead, use pH-neutral cleaners, light pressure washing, and proper sealing to safely restore and maintain your travertine’s natural beauty.
If your pavers are heavily stained or weathered, consider hiring a professional stone restoration specialist who can clean and reseal them without risk of damage.
