How to Clean Stone Tile Floors & Grout

Natural stone flooring is durable and long-lasting; however, care must be taken when cleaning stone tile floors and grout. Although stone tile flooring can withstand a lot of wear and tear, certain cleaning products may cause damage to the surface. Clean stone tile floors and grout properly to preserve their beauty and increase their lifespan.

Sweep the floor with a broom or vacuum cleaner. Use a soft-brush attachment on the vacuum cleaner so that the floor is not scratched. Sweep along the grout lines as well as the face of the stone tiles.

Fill a bucket with warm water. Add a few drops of mild dish soap to the water.

Scrub the grout with a soft-bristled scrub brush or old toothbrush. Dip the brush into the bucket of soapy water and scrub the grout briskly to remove dirt and grime.

Dip a sponge mop into the bucket and wring it out well. Mop the stone tile floor thoroughly with the soapy water. Mop the grout lines as well to pick up the dirt and grime that was removed with the scrub brush. Rinse and wring out the mop frequently. Change the bucket of mop water as it becomes dirty.

Discard the bucket of soapy water once you have mopped the entire stone floor. Rinse out the bucket well and fill it with plain, warm water. Rinse out the mop thoroughly with water.

Mop the entire floor again with the plain water. This will rinse away any soap residue from the floor and grout. Change the bucket of rinse water frequently as it becomes soiled.

Dry the floor with a clean rag to remove any excess moisture or streaks left on the stone. Switch to a fresh rag as one becomes saturated with moisture.

Use ammonia if the floor and grout is heavily soiled and in need of a deep cleaning. Mix ½ cup ammonia with 1 gallon warm water and clean the stone tile floor and grout in the same manner described above. Be sure to rinse the floor with plain water and dry with a soft rag.


Do not use products containing vinegar, lemon juice or other acids. Avoid using abrasive cleaners on stone flooring.
