Granite is made of natural stone and is reactive to chemicals. Certain chemicals may cause granite to stain or etch and may be damaged permanently. This is why it is also important to mind the type of materials or cleaning apparatus to use.

When done properly and consistently, cleaning your granite countertops can be very rewarding. Not to mention it keeps your countertops safe from any bacterial, fungal, or mold growth.

Before you start cleaning

The first thing you would want to do is to clear your countertops of anything on its surface. this gives you a chance to do some quick assessment of the work in front of you. Also, if there is damage to your sealant, you will need to prioritize its repair to avoid further damage. Wipe off, with a clean microfibre cloth any food or beverage residue that might be resting on the surface.

There are a few materials needed to carry out deep cleaning your granite countertops. Most of them are household items that you most probably already have. First, wear gloves when you clean. Soaps and detergents may be corrosive with prolonged exposure. This also helps you avoid scratches when cleaning. The other materials are dish soap, make sure to read the label, and look out for acidic components, a microfibre towel, a bowl, and warm water.

Deep Cleaning Your Granite countertops

Step 1: Inspect your countertop

Once you have removed any containers or utensils sitting on the countertop surface, take a quick glance at the entire surface. You will want to look out for any scratches and discolorations. Food, water, and beverage residue will be a common sight. Also, look out for areas that are starting to rust. Rust is common if you have metal containers sitting on the countertops for extended periods of time.

Step 2: Wipe off any residue

Take a clean microfibre towel and damp it in warm water. Give your granite countertop a clean once over. This will take care of most of the dust, watermarks, food particles, beverage, and grease left standing on the surface.

Step 3: Deep Cleaning

Deep cleaning is easier than you think. It does require some attention and some patience but an overall easy task that will not take you more than 30 minutes barring any hard to remove stains.

Add 3-5 drops of concentrated dish soap to about a liter of warm water. The water needs to be warm as this improves the reactivity of the soap to the material that you want to remove. Dip the microfiber towel in the soapy water and then wring out the excess. You should be seeing suds surface from the towel. Gently wipe the towel all over the granite surface. Depending on the amount of dirt and grease, you might have to repeat the process about 2-3 times. Remember not to force any material that is hard to remove. If you do encounter this, let the soapy water soak for 2-3 minutes then try to wipe off again, gently. Granite can scratch so really be careful.

Step 4: Dry the Countertops

After you’ve wiped off all the grease and dust and other material, inspect your work. Once satisfied, take a clean microfibre towel and wipe it dry. A chamois is also handy especially if you have a wide surface to clean. It absorbs standing water more effectively. You will still have to use a microfibre towel to wipe it dry. This step is vital since standing water can actually develop water stains if left to dry on its own. Not only that, but bacteria and fungi love moist areas. Your granite countertop should be squeaky clean once you’re done. Once achieved, give yourself a pat in the back for a job well done.

But granite can be scratch, get discolored, and even break under specific conditions. Here are things to avoid when cleaning granite countertops:

Acidic Cleaning Agents

Acids can wear off the sealant which is the protective layer of your granite countertop. Once penetrated it can cause damage to the stone itself. Vinegar has gained popularity over the internet and a lot of youtube cleaning tutorials as a favorite all in one cleaning agent. Steer clear. It is not for granite. Steer clear of any citrus-based cleaning agents too.

Abrasive tools

Granite surfaces can easily scratch taking away the gleam and shine which is the reason you chose the material in the first place. Watch out for sharp objects. Aggressive wiping or cleaning can cause scratches too. Always cay out your cleaning tasks gently.
