Travertine

Calcareous stone with natural voids that are either filled with a softer grout or left open, and either way the holes are where a spill goes.

What travertine can and cannot take

  • Heat Use with care
  • Water and soaking Use with care
  • Acids, including vinegar Avoid
  • Strong alkalis Use with care
  • Solvents Use with care
  • Chlorine bleach Use with care
  • Abrasives Avoid

Always test on a hidden area first and let it dry before you treat the visible mark.

General rules for travertine

Travertine behaves like limestone with an extra complication: the holes.

A spill on filled travertine sits on the filler as well as the stone, and the filler is softer and more porous than the stone around it. On unfilled travertine, liquid goes straight into the voids where nothing reaches it.

So blot fast, poultice over the holes as well as the surface, and expect the pitted areas to hold the mark longest.

Check the label

Travertine is calcareous like limestone, and it has natural holes running through it. Filled travertine has those holes grouted at the factory, and the filler is where a spill goes and where it stays. Unfilled travertine is worse again.

Stains on travertine

Travertine is a limestone formed at hot springs, which is why it is full of holes.

The holes are the difference

Filled travertine has them grouted at the factory with a resin or cement filler that is softer and more absorbent than the stone. Unfilled travertine leaves them open. Either way, liquid collects in them.

The chemistry is limestone's

Calcium carbonate, so acid etches it and the ban on vinegar and limescale removers is absolute.

Filler comes out

Aggressive cleaning, and particularly acid, dissolves the filler and leaves the holes open, which is a visible and expensive change.

It is common in bathrooms

Where acidic limescale removers live, which is the most frequent way travertine gets etched.

  1. Care and cleaning of natural stone, Natural Stone Institute trade body

    Stone trade body guidance that calcareous stone such as limestone and travertine is sensitive to acid so only mild non acidic cleaners are used, that acidic cleaners are still not advised on granite, slate or sandstone because they can hold acid sensitive minerals, that scouring powders scratch stone, that the routine clean is a neutral cleaner or mild washing up liquid in warm water, that organic stains are treated with hydrogen peroxide, and that ammonia and bleach are never mixed.

    Stone restoration specialist describing a poultice as an absorbent powder mixed with a cleaning agent, bicarbonate of soda with hydrogen peroxide for an organic stain, spread about a quarter of an inch thick, covered with plastic wrap taped down and left for 24 to 48 hours, that stubborn stains need more than one application, and that a stone that is deeply etched or discoloured beyond surface penetration needs professional restoration rather than a poultice.

  3. Cleaning grout, Tile Council of North America trade body

    Tile trade body guidance that grout manufacturers do not advocate the use of acids because acids attack the cement in the grout, that grout is alkaline based and is dissolved by acids, that mildly alkaline cleaners are preferred over acidic ones, that oil and wax based cleaners leave a film that attracts dirt, that alkaline cleaner not properly rinsed leaves a sticky residue, and that cementitious grout should be sealed to prevent staining.
