The Ultimate Guide to Cleaning Granite Countertops

There's a reason granite is popular countertop material. It's beautiful, strong, and gives your kitchen a much-needed update. However, it takes a little work to keep them beautiful.

The trouble is there's so much bad advice out there which can leave granite dull and damaged. So how do you clean and maintain granite without damaging it? The first step is a great sealer aka granite impregnator.

Luckily, we have the advice and recommended supplies to keep your countertops looking great. Read on to learn how to clean, sanitize, and protect your granite countertops.

How to Clean Granite Countertops

Never use abrasive scrubbers or steel wool on granite. It can scratch the finish and make your countertops look dull. It's best to use a soft microfiber towel or a wrung-out sponge.

While you shouldn't use acidic or ammonia-based cleaning products, commercial granite does not react to common acids. This includes products like Windex, vinegar, bleach, or lemon juice. While these cleaners are great for streak-free windows or stubborn bathroom stains, they don't properly clean your granite countertops and shouln't be used. Like all other food prep surfaces, commercial granite should be properly cared for. 

We recommend the use of Stone Pro Crystal Clean for routine cleaning because it has antimicrobial properties that kill surface bacteria and viruses. Cleaning with soap and water will affect the look of your granite and make it look dull and lifeless. If you have done this, revive granite with Stone Pro Formula 51 to remove surface residue. Additionally, Formula 51 can and will remove both natural and synthetic waxes from commercial granite surfaces. Please bear in mind Formula 51 is not for daily or routine use. Stone Pro Crystal Clean should be used as a daily cleanser.

For more options on cleaning, see additional granite cleaners. Since these products are specifically made to care for natural stone, you'll get even better results. Unless you have a stain, that's really all you need to do to keep your countertops looking beautiful.

How to Sanitize Granite

The sealant on your granite will keep out most bacteria. Wiping down your countertops with proper cleaners will be enough to protect you from harmful bacteria.

There are some situations when you want a little more sanitization. For example, if you've just had raw chicken on the counter, you need more than just soap & hot water. In that case, you can use a specially formulated product like GranQuartz 111M Kitchen and Counter cleaner. It's safe to use, has a pleasant scent, and won't leave residue behind.

Protecting the Sealant on Your Countertops

When you have a granite countertop installed in your home, it will typically come with a layer of sealant on it but if not will need a quality granite impregnator, like Stone Pro “Ultimate Pro” Impregnator. This sealant acts as a barrier from oil and water-based stain.

Unfortunately, the sealant won't last as long as the granite no matter how well you care for it so expect to reapply sealer after a few years of regular use. A coat of sealant typically lasts two to five years, depending on your cleaning habits and how much you use your countertops.

No need to panic though, it just means you'll need to reseal your countertops. You can either do it yourself with a sealant kit or hire a professional. Before you get your granite countertops resealed, make sure they actually need it. Using too much sealer can absorb oil and cause stains.

To check the sealant, put a few drops of water on the counter. If the sealant still works, it should bead up. If the water soaks in, it's time for a new coat of sealant.

How to Remove Stains From Granite

Commercial granite is measured by its porosity aka the ability to absorb water. There are many things that can cause stains or discoloration. Be sure not to put hot pans directly on sealed granite counters and to wipe up spills quickly.

Sometimes accidents happen. We have options for oil stains like Lithofin Oil-EX. This product is specially formulated to remove stubborn oil stains from natural, unsealed stone. However, you may need additional advice. If you do, please contact us toll-free at 866-801-4225 for help.
