Natural stone is featured in countless homes serving as the material of choice for showers, floors, and primarily kitchen countertops. While it may be tempting to assess the cleanliness of these counters simply by the number of crumbs present, their porous nature allows them to conceal much more than you might think.

So, what does this mean?

Natural stone such as granite and marble are considered porous, which indicates that it has microscopic holes on the surface. These tiny indentations allow liquids, air and bacteria to penetrate the exterior of the countertops. Once these contaminants are present, they are likely to remain harboured in the stone and can potentially become harmful.

Even a thorough wiping with disinfectant wipes will not prevent these particles from entering the pores, nor will it remove them. This makes spills and other countertop mishaps much more serious as they are increasingly difficult to clean.

With the kitchen being one of the most high-trafficked areas in the home, keys, groceries and other miscellaneous items are inevitably placed on the counter surface, leaving it susceptible to the exposure of bacteria and other substances. Over time, these simple exposures can cause the counter to darken or stain, altering the colour from its original appearance.

While there is no way to change the structure of natural stone to eliminate its pores, there are several steps you can take to protect your counters and keep them looking their best.

Natural Stone: Protection and Care

It’s always a good idea to consistently wipe down your counters to remove food particles and other residue – but when it comes to protecting your natural stone in the long-term, the most simple and effective solution is to have it cleaned and sealed. This not only maintains the integrity of the material but prevents future stains and damage.

Although most natural stone is sealed upon installation, the sealant naturally wears off with time leaving the surface susceptible to stains, scratches and bacteria. To maintain your counters and stone surfaces properly, it’s recommended they are cleaned and re-sealed annually.

Depending on the surface, various types of stones present different needs when it comes to the products and techniques used to clean and seal. To prevent damage, it’s crucial to hire a professional that is specially trained and certified, such as COIT.

The technicians at COIT carefully prepare, pre-clean, and pre-seal your surface all before beginning the standard procedure. Once they have honed the surface, they will seal it to protect the pores from unwanted bacteria seeping in. Recognizing how vulnerable natural stone can be, laboratory developed and field tested cleaning solutions are used to cut through tough grease and dirt.

Not only can the colour of your stone be restored, but the experts at COIT always hone the surface to remove any signs of wear and tear, then polish to the desired amount of shine. It is recommended to have your natural stone surfaces cleaned and sealed every 12 to 24 months.


It’s safe to say that many surfaces in our homes may look and feel clean while unwanted contaminants still lurk under the surface. Whether you want to get ahead of allergy season with a Spring clean or make your counters shine again; the Pros at COIT are committed to providing the best cleaning experience possible, leaving you with a healthier and happier home.
