Before you try anything: always speak to a professional before cleaning, treating or applying any product to your stone. Every slab is different, and the wrong product can cause permanent damage. Contact us or a qualified stone restorer first.
Quick answer
Limescale on travertine has to be removed without acid, because descalers that dissolve it will also etch the stone. Soften the deposit with warm water and pH-neutral cleaner, then shave it off carefully with a new plastic razor blade held flat. Heavy build-up is a job for a stone restorer.
First, check what you are dealing with
- Chalky white crust you can feel: limescale. Follow the steps below.
- Smooth dull patch with no crust: etching, often from past descaler use.
What you need
- pH-neutral stone cleaner
- Warm water
- New plastic razor blades
- Microfibre cloths
Step by step
Soften the deposit
Lay a cloth soaked in warm water and pH-neutral cleaner over the scale for 10 minutes.
Shave it off
Hold a new plastic razor blade almost flat and gently push under the scale. Keep the travertine wet as you go.
Repeat and dry
Re-wet and repeat until the crust is gone, then rinse and dry thoroughly.
Check for etching
If the area underneath looks dull, it has probably been etched by past descaler use. See fixing etching.
What not to use on travertine
- Vinegar, lemon juice or "natural" citrus cleaners: they etch travertine.
- Scourers, steel wool and abrasive creams on a polished surface.
- Mixing cleaning chemicals, especially bleach with anything else.
- Bathroom descalers, CLR, vinegar and lime removers.
- Metal razor blades and steel wool.
When to call a professional
If scale is thick or has been there for years, a restorer can remove it with stone-safe products and re-polish any etching underneath. A stone restorer can refill open holes, re-hone the surface and blend repairs into the surrounding stone.
Understanding hard water and limescale on travertine
Travertine is a limestone deposited by mineral springs, so it is calcium carbonate and etches as readily as marble.
Most travertine is honed, so damage usually shows as darker rings, lighter dull patches or fills that look different from the stone around them.

Good to know
Limescale on travertine collects in the texture and fills around taps. A soft brush with pH-neutral cleaner helps loosen it before scraping.
Stop it happening again
Whether yours is ivory, beige, walnut and silver travertine, vein cut or cross cut, repairing it fixes today's mark; protecting it stops the next one. Our clear Stone Protection Film sits over the surface, so acids cannot etch it and liquids cannot soak in. Most travertine is honed and filled, so the Matte/Satin film is the usual match: it keeps the natural, low-sheen look. It is installed across Sydney with a 10-year written warranty.
