Learning how to clean concrete countertops before installation or use is a top priority to avoid damage. Concrete countertops have pros and cons and require specific care like any countertop material. This guide will teach you everything you need to know to maintain your kitchen countertops in pristine condition.
The best way to clean your concrete countertops is with a pH-neutral cleaner following this simple procedure.
A pH-neutral cleaner is the best way to clean concrete counters. Avoid soap. Soap leaves a film just like soap scum in the shower, no matter how much you rinse. Soap makes the surface dull, dingy, and even harder to keep clean. A pH-neutral cleaner (pH 7-9) is more efficient and effective. Spray on, wipe or scrub with a non-abrasive sponge, and buff dry for no streaks.
Dish soap is often recommended as a cleaning agent for all types of countertops because it is safe and won’t harm the surface. But it is messy, requires a lot more time and effort, and creates a soap scum buildup.
Many homeowners prefer to use a commercial concrete cleaner or stone countertop and quartz countertop cleaners like this Granite & Marble Cleaning Spray for quick convenience and no soap scum.
This cleaner is pH-neutral, will not damage the finish, does not need rinsing, and leaves a streak-free shine. It simplifies caring for concrete countertops on a daily basis.
Many cleaners and household products can damage concrete. You cannot simply use whatever you have on hand. It’s imperative to learn what products you should use to clean concrete countertops.
Here’s a list of products and cleaners safe for concrete countertops.
You should not use any bleach-based cleaners, abrasive powders, acidic cleaners like vinegar, lemon or citrus, Lysol, or hard water mineral cleaners like CLR for concrete countertop care.
Such harsh or caustic cleaners are not safe and can remove the sealant, discolor the dye, or cause etching and physical damage to the surface and finish like you see in the photo below.
Diluted bleach is sometimes an option to remove a stubborn stain (discussed below), but only for a quick application. And you should test it first.
Use isopropyl alcohol diluted with water for disinfecting concrete countertops.
Important: Note that many brand-name disinfectant products like Clorox Wipes or Lysol Wipes and common sanitizers like bleach and vinegar can cause etching and damage. So, do not use these products.
The Mold & Mildew Remover for granite, quartz, and stone is another option to effectively and safely sanitize countertops. It is non-damaging on all hard surfaces.
Concrete countertop stains can occur from foods, drinks, harsh chemicals or cleaners, or hard water deposits.
Each type of stain requires a different solution. Sometimes baking soda or bleach, or other damaging cleaners may be needed to get a stain out. So removing a food stain, acid stain, or water rings requires careful attention and detailed explanations.

Several options exist to make your concrete countertop shiny depending on the level of sheen or gloss you’d like and how the concrete surface was finished.
There are pros and cons to each option above and the different types of sealants or topical coatings used to protect the concrete or provide a particular look.
Thoroughly discuss these choices with your concrete countertop fabricator before installation to ensure the result will be what you want.
Proper cleaning and timely maintenance can help keep your concrete counter tops in good condition for a long time. Here’s how to protect it from damage from heat, scratches, cracks, stains, and so on.
Sealing your concrete kitchen countertop with an appropriate concrete sealer is necessary to protect against stains.
Several different types of sealants are available and applied depending on how the surface is finished or the concrete mix. White concrete tends to be more stain-resistant.
For sealing concrete countertops you’ll need to choose a topical or penetrating sealer.
Topical coatings can be applied to rough-honed finishes. Penetrating sealers are needed for polished finishes.
Our best recommendation is Stain Proof Permanent Penetrating Sealer.
If you’re using a penetrating sealer, you must finish it with a coat of wax. Wax provides additional protection when applied to any finish or sealant. You should apply wax to the cement countertop once or twice a month, especially in the kitchen.
You can check if the wax layer is intact by dropping a bit of water on it. If it doesn’t darken the concrete, it’s okay.
Daddy Van’s Beeswax is our top pick. Very pure product. Don’t use car wax. It has other ingredients that are not good for concrete.
Most scratches are in the sealer and not in the concrete itself. To repair scratches follow these tips:
Yes, you can use sandpaper on concrete floors or counter tops to repair etch marks, rough spots, hone or polish the surface, or prep for sealing.
Make sure the surface remains wet when sanding and periodically remove all debris to keep from burnishing the cement. Diamond pads or discs are the best options, but you can use metal or wood sandpaper.
This Manual Marble Polishing Pad Kit is pretty handy for etching repair on concrete.
DIY sanding of small areas is doable, but sanding large areas is best left to professionals.
Yes, concrete countertops require more maintenance compared to other countertop materials. Granite, quartz, quartzite, porcelain, butcher block, laminate, and even marble countertops are not as demanding. Concrete countertops must be sealed and regularly waxed. But even then the surface can be stained, etched, scratched, cracked, chipped, and hot pans can damage sealants. Repairs are often more complicated and expensive than other types of countertops.
A new concrete countertop sealer should be applied every six months to three years, depending on use and condition. Apply a concrete wax on top of the sealer monthly or as needed for additional stain protection.
Pure Beeswax is the best type of concrete wax to apply. Do not use automotive wax as the additives are not suitable for concrete. Apply the wax over the entire surface with a soft cloth or pad. Rub vigorously and buff to a shine.
Be careful using bleach on a concrete countertop. You may read elsewhere that using bleach on concrete is okay, but it depends on how the concrete is finished, dyed, and sealed. Bleach can be used with a short contact time to remove some stains, but test first. Bleach and other caustic or acidic cleaners may etch concrete and damage sealants.
White vinegar is acidic and should not be used to clean concrete countertops. Acidic or caustic cleaners, including many common household cleaners and brand-name products, can etch concrete causing dull, chalky, rough, and pitted spots.
Make a concrete countertop look new by honing it, polishing it, and applying a new sealer. Go over the entire surface with 50-grit diamond polishing pads. Progress to finer-grit pads (200, 400, 800, 1600) for the desired level of finish. Apply a concrete stain. Apply the correct concrete sealer for the level of finish.
