Pet Urine on Natural Stone Floors (Marble, Travertine, Slate)

Your dog or cat had an accident on a marble, travertine, limestone, slate or granite floor. Here is what to do first, what to clean it with, what to keep off it and when to call a stone professional, using what the Natural Stone Institute, Daltile, Arizona Tile, the AKC and Humane World for Animals say.

Step 1: Blot it right away

Speed matters on any floor. The AKC says: "Regardless of what your dog has peed on, your best course of action is to act fast."

On stone, blot rather than wipe. The Natural Stone Institute's advice for spills is: "Blot the spill with a paper towel immediately. Don't wipe the area, it will spread the spill. Flush the area with water and mild soap and rinse several times. Dry the area thoroughly with a soft cloth. Repeat as necessary."

Why stone is different: stains and etching

Stone can be hurt in two ways. The Natural Stone Institute explains the chemistry: "Calcareous stone is composed mainly of calcium carbonate, a chemical compound commonly found in natural stone, shells and pearls. Calcium Carbonate is sensitive to acidic solutions so mild, non-acidic cleaners are recommended."

Siliceous stone is tougher, but the Institute says it "is generally resistant to most acids found in kitchen settings, although acidic cleaners are still not recommended, as these stones may contain trace levels of minerals that are acid sensitive."

Arizona Tile names the stones most at risk: "All calcite-based stones, such as marble, limestone, onyx, travertine, etc., are sensitive to acids." It adds: "Many slates will also etch, and so will a few "granites"".

Daltile describes what acid damage looks like: "The result is not a stain, which could be removed, but an etching of the stone surface, which cannot be removed without refinishing the stone. In polished finish stones, a mild acid attack will usually manifest itself as a "dull" spot within the surrounding glossy surface."

What about urine itself? The Natural Stone Institute lists urine among organic stains: "Organic (coffee, tea, wine, fruit, tobacco, paper, food, urine, leaves, bark, bird droppings) May cause a pinkish-brown stain and may disappear after the source of the stain has been removed." We found no stone industry guidance saying whether pet urine on its own etches stone, so treat any dull spot as a question for a stone professional.

Step 2: Clean with a neutral stone cleaner

The Natural Stone Institute says: "Clean stone surfaces with a neutral cleaner, stone soap, or a mild liquid dishwashing detergent and warm water. Similar to any item cleaned in your home, an excessive concentration of cleaner or soap may leave a film and cause streaks. Follow manufacturer recommendations."

Daltile's method: "A solution of the pH neutral cleaner and water mixed to manufacturer instructions should be applied to the stone surface with a sponge or spray bottle." It also notes: "Some textured stones may require a different cleaning method or additional procedures not specified here."

Step 3: Rinse and dry

The Natural Stone Institute says: "Rinse the surface thoroughly after washing with the soap solution and dry with a soft cloth. Change the rinse water frequently." Daltile adds: "Make sure to always limit the time liquids sit on any type of natural stone and dry the surface thoroughly."

What to keep off stone

Arizona Tile warns: "Do not use scouring powders or creams; these products contain abrasives that may scratch the surface. Do not use vinegar or any cleaners containing acids or strong alkaline agents."

Daltile says: "Stone cleaners should never contain acid or bleach. Acids, even a light solution of vinegar and water, will etch and eventually damage many varieties of natural stone."

The Natural Stone Institute also warns: "Do not mix ammonia and bleach. This combination creates a toxic and lethal gas."

Sealers: what they do and don't do

Arizona Tile says: "Unsealed stone is more susceptible to absorbing moisture, dirt and cleaning chemicals." But a sealer is not a shield. The Natural Stone Institute says: "Sealing does not make the stone stain proof, rather it makes the stone more stain resistant." It also notes: "When consulting with your stone supplier, you may find that many stones do not require sealing."

If you do seal, Daltile says: "Always reference manufacturers' literature for specific information on the duration of the sealer's protection and make sure that the sealer is applied in strict accordance with the manufacturer's instructions." Sealed or not, the cleaner warnings above still apply.

The grout between stone tiles

If the accident reached the grout lines between stone tiles, see our guide to cleaning dog pee from tile and grout. Whatever you use on the grout will also touch the stone, so the warnings above still apply.

Stains that won't lift: poultices and pros

For a stain that has soaked in, the stone bodies describe a poultice, an absorbent paste. The Natural Stone Institute warns: "Poultice procedures may have to be repeated to thoroughly remove a stain, but some stains may never be completely removed." For help, it says to "call a stone professional (recommended)."

The Institute's organic stain section, which covers urine, gives an indoor method using strong household chemicals. We don't repeat it here; read it on the Natural Stone Institute care page or ask a stone professional.

Daltile says: "If the stain is old or has penetrated the stone deeply, a poultice may not be enough to remove it." And: "CAUTION: Poultice may dull the shine of the polished stone. If this occurs you will need to use a stone polish to restore the natural shine."

For etching, the Natural Stone Institute says: "Contact your stone dealer or call a professional stone restorer for refinishing or repolishing etched areas." If the spot is months old, see our guide to old, dried pet urine stains.

Stopping repeat accidents

The AKC says: "Lingering scent can draw your dog back to the same area, reinforcing accidents." Humane World for Animals says: "If your pet is having regular accidents, have them checked by a veterinarian to rule out medical causes."

If the smell returns, see why pet urine smell comes back after cleaning. For the habit itself, read why dogs and cats keep peeing in the same spot and dog marking indoors. For patios and garages, see dog pee on concrete.
