Why are countertop cleaning and sealing important? Countertops can sometimes get missed when you think about what should be professionally cleaned and sealed.
Professional countertop cleaning removes embedded dirt, oils, and buildup that everyday wiping may leave behind, while sealing helps protect porous natural stone such as granite, marble, and travertine from absorbing liquids and developing stains. Most natural stone countertops should be evaluated for resealing every 1–3 years, depending on the stone's porosity, usage, and existing sealer. Professional deep cleaning may be needed sooner for stubborn buildup or staining. Engineered quartz countertops generally do not require sealing.

Do you know the benefits of countertop cleaning and sealing? Why are countertop cleaning and sealing important? Countertops can sometimes get missed when you think about what should be professionally cleaned and sealed.
Countertops come in all different materials, and all of them need to be sealed to ensure longevity. I will walk you through all the info you will need.
Getting your countertops professionally cleaned and sealed is highly recommended. Even though you clean your countertops daily or multiple times a day because of cooking and things like that, it doesn't mean that you are getting them absolutely clean.
Countertops are typically a form of natural stone - granite, marble, travertine, etc. Natural stones can be very absorbent if not adequately taken care of and prepped. Now you may be thinking I have granite, and granite is very dense, so I am OK to not worry about my countertops.
This is a very common miscommunication that people encounter. You are correct; granite is a much denser stone than marble or travertine, but it is still a natural stone, and if not correctly taken care of, you can have granite issues.
Think about it, countertops see all sorts of chemicals, products, and foods, and they see these things all day long and every day. Countertops can collect all kinds of bacteria and other things as well. Countertops can even grow E. coli and other yucky stuff because of their use.

This is why we highly suggest you have your countertops cleaned and sealed every 12-18 months. By having your countertops cleaned by a professional, you are getting a deep, sanitizing clean that lifts and removes almost all the bacteria living on the surface. It also helps prevent staining within the countertops, leaving them looking beautiful.

We also highly recommend having your countertops thoroughly sealed every 12-18 months to help prevent different bacteria and chemicals from absorbing into the stones and staining them. We also offer many other services for countertops.
No matter where the countertop is located (bathroom, kitchen, etc.), we recommend taking good care of it.
When we clean countertops, we use a citrus-based cleaner that is made for countertop cleaning. We spray the countertop, let the cleaner dwell, and then use our truck-mounted system to extract and sanitize it.
This system uses high heat and high pressure (220-degree water at 1200 PSI). This will lift and remove all the chemicals, dirt, and grime that may be on your countertop.
Once the countertops are cleaned thoroughly, we apply a hybrid solvent penetrating sealer made for the different types of countertops. We have a couple of sealers, depending on the stone.
We flood the countertops with the sealer, let it absorb in, and then wipe away any excess. If we need to do a quick buff with terry cloths to even out, we most of the time do not have.

We also offer color sealing (for ceramic and porcelain countertops only). We can color seal the grout lines if you have a ceramic or porcelain countertop.
This sealer absorbs into the grout lines, clogs the pores, and helps prevent staining. Color sealing is only used on grout lines, not other stone countertops.

Another service we offer to countertops is honing. You may notice (especially on marble) that there seem to be thin scratches or marks on the countertop over time. These marks can be etching or scratches in the stones.
We can remove the etching or scratches and achieve a matte, satin, or semi-gloss look for the countertops with honing. Honing is kind of like we are sanding a thin layer off the top of the stone to reveal the undamaged stone. If these sheens are not shiny enough, we can help with that.
One last service we offer for countertops (stone ones) is polishing. Polishing will bring the stone countertops to a high shine, also known as a high gloss look.
When we polish, we use a compound that reacts with the stone's calcium, making the stone denser and bringing out the stone's true beauty.
Polishing is excellent for achieving that brand new countertop look and helps harden the stone, making even fewer things able to absorb into it. With polishing and sealing, you are sure to give your countertops an excellent, strong barrier against the different elements that come in contact with them.

All these different services help ensure that your countertops stay clean, sanitary, and looking their best longer. Sometimes countertops get forgotten about because we feel I clean these so often.
I am sure they are completely fine, but as you can see, this may not be the truth. Take care of your countertops right away or start now. This will help you know you are keeping your friends and family healthy by knowing you're working with protected countertops.
Natural stone surfaces require waterproofing (or sealing) due to their porosity. Granite, marble, travertine, soapstone, and other natural stones have tiny pores that absorb liquids.
Red wine, coffee, cooking oil, and cleaning products can penetrate porous stone and leave permanent stains.
Softer stones, such as marble and travertine, absorb liquids more quickly than granite and therefore require more frequent sealing. If you have marble countertops, plan to seal marble more often than granite. Light granites also tend to be more porous than dark varieties and benefit from more frequent waterproofing.
Dense stones, such as "Absolute Black" granite, absorb very little liquid; consequently, they require less frequent treatment, and the sealant may barely penetrate the stone at all. This is why dense, dark granite handles spills better than lighter stones.
Quartz countertops are different. Quartz is an engineered stone that is often non-porous and low-maintenance; therefore, it does not require waterproofing. However, it does require gentle cleaning to preserve its finish.
Prompt cleaning prevents stains on porous materials like granite and stops the buildup of soap scum and water spots, preserving their appearance. Homeowners should also avoid harsh chemicals such as bleach, ammonia, or vinegar, which can weaken the sealant and dull the finish.
A dirty countertop can quickly become a breeding ground for bacteria, odors, and stubborn stains, making routine care even more important for both hygiene and appearance.
Beyond daily care, proper countertop maintenance directly influences home value, as clean, well-kept surfaces make a strong impression on potential buyers.

While quickly wiping up spills helps prevent surface stains, only professional sealing creates a protective barrier that blocks liquids from penetrating the stone. Experts also inspect for cracks, chips, and worn sealant, helping prevent costly repairs and extend the life of your countertops.
Natural stone can trap bacteria beneath the surface. Professional deep cleaning sanitizes the stone more effectively than household cleaning, creating a safer kitchen. Properly sealed countertops can harbor up to 99% less bacteria than unsealed ones.
Professional care restores color, shine, and cleanliness, making your kitchen look new again. Real estate experts agree that well-maintained countertops significantly improve resale value, making this investment beneficial whether you plan to stay or sell.
Yes. Most granites are denser than marble or travertine; many homeowners mistakenly believe that this characteristic eliminates the need for sealing. This is one of the most common misconceptions.
Although granite is highly resistant to heat and daily wear and tear, it remains a natural stone. If left untreated, unsealed granite can absorb oils and liquids that may darken the surface and leave permanent stains.
A dense stone simply absorbs substances more slowly; consequently, damage accumulates over time rather than appearing overnight. The best way to protect granite countertops is proper sealing and regularly.
You can check your seal at home in about 15 minutes with a simple water test:
Areas around the sink and cooktop wear down fastest, so test those spots first.
For most stone countertops, proper maintenance involves regular cleaning and sealant application every 12-18 months. Use mild soap, pH-neutral cleaner, and a microfiber cloth to wipe spills immediately, avoiding water spots and dust buildup.
If raw meat, lemon juice, or other acidic spills occur, clean immediately with warm water and a gentle cleaner. Avoid bleach or ammonia, as harsh chemicals can damage countertop material and sealant. You can use a soft cloth or sponge to clean countertops to prevent scratches.
Before sealing, countertops should be free of dust, spills, and water spots. After sealing, continue using mild dish soap, a microfiber cloth, and warm water for regular cleaning to extend durability and prevent the biggest problems like staining and etching.
Unsealed countertops accumulate far more than just crumbs. Over time, you will notice the appearance of:
A quick wipe with a sponge cleans the surface layer but fails to reach impurities that have penetrated the stone. That is where professional cleaning comes in.

Granite countertops and quartz countertops are durable, but they still require proper care to maintain their appearance and longevity. Your granite needs some care, too.
Daily cleaning with mild, non-abrasive cleaning products helps prevent residue, grease, and soil buildup on granite surfaces or quartz surfaces.
Stainless steel appliances in the kitchen can sometimes contribute to cross-contamination, so it’s important to wipe down granite surfaces around these areas carefully. Note that using a dry, lint-free cloth can help achieve a smooth finish and avoid scratching the surface.
Regular deep cleaning and soaking stubborn spots ensures your counter remains sanitary and highly effective at resisting bacteria and odors.
Following a consistent maintenance process helps protect large areas of stone surfaces and preserves the natural beauty of your countertop. Always determine the proper technique for each type of surface to maintain its finish and longevity.

A clean, organized kitchen not only looks inviting but also promotes better mental well-being and reduces cooking-related stress. One of the simplest ways to maintain this calm and order is by cleaning your countertops daily, which helps eliminate spills, stains, and crumbs before they become permanent problems.
When cleaning, blot spills rather than wipe to prevent liquids from spreading across the countertop, and always dry the area afterward to avoid water spots or streaks.
Following these basic steps can save you from common countertop mistakes and keep your kitchen both functional and beautiful.
Bleach, ammonia, vinegar, and lemon juice can strip sealant and etch natural stone. Use a pH-neutral cleaner or mild dish soap with warm water for daily cleaning. Professional cleaners made for your countertop material are safest.
Spills from wine, coffee, citrus, or oil can stain or etch stone quickly. Keep a microfiber cloth or paper towel handy and wipe spills immediately to protect your sealant and prevent permanent marks.
Hot pots can crack or discolor stone, and cutting directly on surfaces risks scratches and bacteria buildup. Always use hot pads and cutting boards to protect your kitchen countertops.

Abrasive pads and powders can damage the sealant and scratch the stone. Use a gentle cleaner and a soft cloth, letting the cleaner lift stains. For stubborn stains, call a professional.
Sealant wears down over time. Regular cleaning and resealing on schedule prevent stains, water spots, and damage before they become costly problems.
We recommend professional cleaning and sealing every 12 to 18 months for kitchen countertops, bathroom vanities, bar tops, and any other stone surfaces in your home.
High-traffic kitchens, light-colored granite, and marble countertops require less frequent maintenance. It is advisable to reseal sooner if:
Honing and high-gloss polishing are both part of the natural stone restoration process, yet they yield different finishes.
Honing removes a thin surface layer of stone to reveal the pristine material beneath. This technique eliminates deep acid etching and fine scratches, common issues on marble countertops, resulting in a matte, satin, or semi-gloss finish.
High-gloss polishing creates a brilliant shine. For calcareous stones like marble and travertine, we apply a polishing agent that reacts with the stone’s calcium content, helping to tighten its surface structure.
For granite, we use specialized polishing powders and pastes applied with a variable-speed handheld polisher. Both methods serve to revive the stone's natural beauty.
Combining polishing with a new water-repellent treatment (sealer) gives your countertops effective protection against liquid spills and everyday wear and tear.

Professional cleaning of granite countertops goes far beyond simple scrubbing. Deep cleaning removes the stubborn dirt, grease, and residue that routine daily maintenance cannot eliminate.

Using the appropriate products and the lint-free cloth included in the kit restores your countertop to its original appearance without damaging the granite surface. Imagine the result: a polished, radiant granite surface instead of a dull one, while also saving money in the long run by avoiding unnecessary repairs.
After cleaning, applying a high-quality impregnating agent (sealer) provides long-lasting stain protection and preserves the granite's shine and polish. Following the label instructions ensures safe application and prevents damage to your countertop.
Any excess product should be wiped away; additionally, periodic reapplication may be necessary to maintain effective protection.

How often should granite countertops be sealed?
We recommend sealing granite countertops every 12 to 18 months. Lighter-colored granites may require more frequent treatment, while dense stones—such as Absolute Black granite—require it less often. Perform the water test to check.
Do quartz countertops need to be sealed?
No. Quartz countertops are manufactured products that are generally non-porous; therefore, they do not absorb liquids the way natural stone does. However, they do require gentle daily cleaning.
How do I know if my countertop needs sealing?
Place a few drops of water on the surface and wait 10 to 15 minutes. If the water beads up, the protection is effective. If it is absorbed and darkens the stone, it is time to apply a new coat of sealer.
What is the best way to clean natural stone countertops every day?
Use warm water with mild dish soap or a pH-neutral stone cleaner, along with a microfiber cloth. Then, dry the surface to prevent water spots.
Can you remove etching from marble countertops?
Yes. Matte sanding (or honing) removes a thin layer of stone to eliminate deep corrosion marks and scratches. Polishing can then restore a high-gloss finish.
What happens if you leave excess sealer on the countertop?
Excess sealer can dry and form a sticky film or a dull haze on the surface. Wipe it off just a few minutes after application.
