Know your stone

The natural stones that we offer in our range can be classified into three categories according to their compositions: granites, siliceous stones and limestone stones. Knowing the difference between these compositions is essential when choosing cleaning products.

Silica stones are composed mainly of particles of silica, feldspar or quartz. This type of stone includes: granite, slate, sandstone, quartzite, brownstone and bluestone. This mineral composition makes the siliceous stone very hard, massive, dense and resistant. It is easy to clean with mild acidic cleaning solutions.

Limestone contains in particular crystallized calcium carbonate. Limestones include: marble, travertine, limestone and onyx. Limestones, in general, are sensitive to acids which react directly with the stone. This stone therefore requires more precautions as well as different cleaning procedures than siliceous stone or granite. Similarly, since limestone is generally soft, shocks on one of its angles or edges should be avoided.


Maintenance tips

To get the longest life and preserve the beauty of your natural stone, follow this list of tips:
Basic rule: Avoid acids (especially for limestone)
1. Be sure to clean immediately (i.e., within 5 minutes) any acid in contact with your worktop: lemon or other citric fruits (orange juice, apple juice, …), vinegar, wine, champagne, …
2. Avoid acid-based cleaning products

How to clean?

1. Clean your surfaces with a soft cloth that is dry or lightly dampened with soapy water
2. Use a neutral cleaner, household soap or a mild liquid detergent (e.g. dishwasher with lukewarm water)
3. So rinse the surface thoroughly after washing with the soap solution.
4. For cleaning scale around the faucet, which often requires an ‘anti-scale’ product, use products that are relatively mildly abrasive (e.g. white vinegar, less aggressive), keep the exposure of the stone to the detergent product short and rinse thoroughly.

“Super-cautious” advice for use (also for limestone)

  • Trivets: Although all types of stone resist heat well, the use of trivets or mats is recommended.
  • Coasters: Use coasters, especially those containing alcohol or citrus juices.
  • Daily cleaning: Regularly dust the surfaces with a dry, untreated feather duster, or with a cloth lightly dampened in soapy water. Dust and dirt are abrasive and can damage your stone over time. In addition, daily maintenance prevents cleaning with more aggressive products from becoming necessary.
  • Handheld vacuum cleaners: Make sure the metal or plastic attachments or wheels aren’t worn, as they could scratch the surface of some soft stones.

Cleaning products to avoid:

There are many quality products for cleaning limestone. You have to avoid:

  • Products containing lemon, vinegar or other acids which can tarnish or damage limestone.
  • Scouring powders or creams containing abrasives.


How to remove stains?

  • Stains from acids cannot in principle be removed since it is not a real stain – that is to say an “addition of material” – but a “removal of matter” resulting from a chemical reaction between acid and calcium.
    Nevertheless, acidic stains can be removed by repolishing the worktop. Thus, any worktop can be repolished as many times as you wish and thus be returned to its initial state.
  • Oil-based stains (grease, plumber’s putty, tar, cooking oil, milk, cosmetics) must be chemically dissolved so that the source of the stain can be removed or rinsed away. Clean gently with a mild, liquid product containing one of the following: household detergent, mineral spirits or acetone.
  • Other tasks, e.g., inks, paint, metal (rust, etc.): For any other type of task, do not hesitate to contact us. We will always be available to advise you on the maintenance and cleaning of your worktop.
