How to Clean Sandstone

Updated March 23, 2017

Sandstone is a natural stone used in a variety of applications inside and outside the home. Countertops, walls, floors, sculptures and tiles are all examples of how sandstone is used. Sandstone is porous, which means that extra care must be taken when cleaning and maintaining it. Chemicals from liquids can seep into the stone and cause discolouration. To maintain the beauty of the sandstone, it must be cleaned regularly and correctly.

Seal the sandstone. If applicable, sealing the sandstone is the first step in helping to keep it clean. Walls and tiles are examples of sandstone applications that can be sealed. Sealing prevents the porous surface from being penetrated. Apply one coat of sealer with a brush, clean cloth or lambswool applicator. Allow 24 hours for it to dry.

Clean any spill that occurs on the sandstone as soon as possible. The longer the liquid stays on the sandstone, the greater the chance that it will damage it.

Dust the sandstone regularly with a nontreated, dry, clean dust mop. Try to cover as much of the surface area as possible. Alternatively, you can use a vacuum to dust the sandstone as long as you use a soft bristled attachment that will not damage the stone.

Wipe down the sandstone with a clean, soft cloth that is dampened in plain warm water. Commercial cleaners contain harsh chemicals which will cause staining and erosion and should be avoided.

Spray heavily soiled sandstone with a neutral pH cleaner. Spray the cleaner directly on the sandstone and wipe it with a clean cloth. Rinse the sandstone with water to remove any trace of the cleaner.


Do not scrub the sandstone with harsh bristles because it will damage the stone.
