Is a Granite Countertop Hygienic?

When it comes to food preparation and everything else that you do in the kitchen, the first thing that you must consider is the cleanliness and hygiene of the things that you use. Improper food handling and dirty implements can cause food poisoning and other illnesses. Countertops are where you usually prepare food for cooking and eating, and you need to make sure that they are hygienic and will not cause any illnesses. If you have a granite worktop, you must be thinking if it is safe to prepare food on it.


Granite is not non-porous, but it is less so compared to other types of stone countertops, such as marble. Granite has tiny pores where water and other liquids and particles can accumulate, but with the help of a sealant, it seals the surface so that nothing gets past the barrier that can cause health issues over the years.

The sealant will also prevent scratches. If you want to have a granite worktop London installers are aplenty, and they can do the sealing for you. You can also apply a granite sealant on your worktop from time to time to ensure that the sealant has not worn off from everyday wear and tear.

Polished versus honed

Polished granite is less porous than honed, and the former seals the pores on the surface. It means that a polished granite countertop more efficiently repels moisture. We all know that a moist and dark place is bacteria’s favourite breeding ground. Without moisture, there is no environment for bacteria to thrive.


Your granite worktop will last you for decades without any problem, provided you perform all the necessary steps to ensure that it is always clean, sanitised and used correctly.

You can also use isopropyl alcohol diluted in water. A soft cloth is enough to wipe it down. The use of harsh chemicals in cleaning the worktop will make it lose its shine, as well as remove the sealant that protects the whole countertop from contamination. Do not let stains sit for too long as they can be harder to remove.
