Cleaning products and tools

To properly sanitize your granite countertop, you’ll need the items listed below:

  • warm water;
  • mild or gentle dish soap;
  • dish cloth;
  • (two) clean microfiber cloth or towel;
  • 70% isopropyl alcohol;
  • spray bottle.

These are basically a homemade, ordinary selection that everyone can get their hands on. That said, there are some overall tips to prevent bacteria and other microorganisms from settling on top of countertops.

First of all, maintain an effective sealer (more on that in a bit). That will serve like a cover against outside elements and nothing will sit on the stone itself. Second, you should disinfect it weekly if you cook in the kitchen every day. Third, never chop meat or any kind of food unless it’s on a cutting board. Lastly, don’t let spills (especially sweet substances) dry off on the surface without wiping them. As we all know, moisture will attract bacteria and even rats.

Things to avoid

Of course, there are commercial and more powerful cleaners in any nearby store that you can always buy. There’s nothing wrong in using a recommended cleaning solution, but make sure to follow the instructions on the label.

There are chemicals, however, that you should never use – because they will damage your granite permanently, be it the sealer or the surface itself. These include:

Sealing is important!

We’ve mentioned several times on this blog: to truly preserve the beauty and texture of your granite, you must seal it at least once a year. Applying coats of sealer is crucial to extend your countertop’s durability over time.

As granite stones are porous – in other words, prone to water absorption – we need to take extra measures to protect the surface from cracks, stains and scratches. Old balconies and vanities that were never taken care of have to be changed entirely, which affects your own budget more than anything.
