How to Care for Granite Countertops


Granite is one of the most popular countertop choices, and for good reason. This natural stone, which is formed over time from volcanic magma, is one of the most durable options available. It is also resistant to high temperatures and easy to clean.

There’s always been a misconception that granite countertops require no maintenance. But reality is, it might demand the least when compared to other materials, however, there is still some work to be done to keep your investment looking great.

To Seal or Not Seal

Since all stones are porous - although the degree differs amongst the type of stones – applying a seal on the surface will prevent spills from penetrating the surface which causes discoloration.

Granite countertops are usually sealed when installed and experts recommend resealing every twelve months. However, you can do simple tests to see if it is necessary.

Method 1: sprinkle a few drops of water on the granite countertop and wait for 4 minutes. If the water is absorbed into the granite, then resealing is required.

Method 2: put a drop of mineral oil on the granite and wait for 10 minutes. Wipe off the oil and see if a dark spot has appeared. If it has, then resealing the granite countertop is necessary.

*NOTE: the dark spot will fade within 30 minutes after it first appeared.

Repeat the sealing test once very few months to ensure your granite countertop is well protected.

Basic Cleaning

The surface of a well-sealed granite countertop is relatively impervious to bacteria. Therefore, to perform basic cleaning, soak a dish cloth with warm soapy water (use dishwashing soap since it consists of antibacterial properties), remove excess water and wipe the surface. This is adequate for daily sanitizing.

For occasions where a stronger disinfectant is required, mix together a 50:50 solution of water and 91% isopropyl alcohol. Spray solution onto granite and let it sit for 3-5 minutes. Rinse countertop with water and dry with a clean cloth.

Things to keep in mind

  1. Although a well-sealed granite countertop is impervious, do clean up spills immediately
  2. Use trivets or mats under hot dishes and cookware to minimize damage
  3. Place mats under china, ceramics, silver and other objects can avoid scratches
  4. Frequent use of harsh or abrasive cleaners and sponges and acidic cleaners will dull and weaken the sealant over time. Therefore, avoid using Windex, vinegar, lemon, lime or anything with ammonia or bleach.

With proper care and maintenance, your countertop will last for years to come and remain looking as beautiful as it was first installed.
