The 10 Best Concrete Cleaners of 2023

Best Overall

Zep Neutral pH Floor Cleaner Concentrate

View On Amazon

If you have sealed concrete floors, Zep Neutral pH Floor Cleaner is an excellent choice. Thanks to its neutral pH formula, it preserves the floor’s polish without stripping its protective coating. Zep also improves the overall appearance of floors by restoring their shine. It’s also safe to use on other types of indoor and outdoor flooring, including marble, granite, vinyl, and stone. 

This concentrated formula can make up to 128 gallons of solution, providing plenty of cleaning power at an affordable price. In lieu of a traditional string mop, the manufacturer recommends applying the cleaner with a microfiber mop to improve maneuverability. Zep doesn’t require any rinsing, which is a nice convenience, but it may leave behind a sticky residue. If this happens, you can easily mop the floor with water as a final clean. Just be sure to also wear rubber gloves during the process, as a precaution.

Please note that this product should not be used on wood or unsealed concrete floors. Doing so can result in damage. When it comes to cleaning multiple surfaces, Zep isn’t as versatile as other options, but it's a stellar performer on sealed concrete floors.

Best Budget

Krud Kutter Concrete Clean & Etch

View On Amazon

Krud Kutter contains a unique additive known as "Oil Grabber," which penetrates the surface and dissolves tough stains. This versatile formula can be used to remove grease, oil, mildew, algae, and more. It can also be used on a variety of surfaces, including driveways, patios, sidewalks, basement, and garage floors. 

We think this is also a great product to use before coating, staining, or sealing concrete surfaces. Its phosphoric acid base effectively etches concrete and promotes adhesion. Biodegradable and water-based, the formula is safe to use around surrounding plants and grass. Just note, we read a handful of reports that say Krud Kutter may cause white spots and discoloration. Be sure to test an area first, if this is a concern.

Krud Kutter comes in a concentrated formula that needs to be diluted before use. The application process will take some elbow grease. The solution should be worked into the surface using a stiff bristled broom until it stops foaming, then rinsed off three times with a hose. Allow the surface to thoroughly dry before applying a stain or sealant. Expect this cleaner to be affordably priced. One 32-ounce bottle can clean up to 200 square feet!

Best Alkaline

Sunnyside 64216 TSP All Purpose Cleaner

View On Amazon

First off, you should know Sunnyside TSP contains trisodium phosphate, a powerful alkaline cleaner that can tackle the toughest stains on concrete. This product is ideal for basements, garage floors, and other contained areas. However, the high phosphate content may be dangerous if it enters outdoor water sources. Sunnyside TSP does an excellent job of removing grease and paint, so it's a great choice for prepping surfaces before painting. 

This powdered formula is concentrated, and needs to be mixed with a gallon of hot water before use. When working with this product, it’s best to wear protective gear, such as gloves and a mask, because TSP can cause skin irritation and burns. You’ll see the best results after scrubbing with a bristle brush, which means it will likely take some elbow grease to apply.

Best for Pressure Washers

Simple Green Oxy Solve Total Outdoor Cleaner Pressure Washer Concentrate

View On Amazon

This pressure washer concentrate uses the power of peroxide to lift dirt and grime, as well as stains from mold, mildew, moss, and algae. It’s ideal for cleaning a variety of surfaces, including concrete, wood, wicker, fabric, stone, brick, and asphalt. Oxy Solve’s biodegradable formula meets the standards of the U.S. Environmental Protection Agency’s Safer Choice program, which means it’s safe to use around plants, pets, wildlife, and waterways.

You’ll likely get the best results by using Oxy Solve with a pressure washer. The manufacturer recommends applying it at a low pressure setting, letting it sit for three to five minutes, and rinsing it off at high pressure. You can also apply the product by hand with a soft-bristle brush or sponge. While Oxy Solve effectively cleans many outdoor surfaces, some say it doesn't work on vinyl siding. Just know that it produces a strong smell, so be sure to work in a well-ventilated space and have a mask and gloves handy.

Best Degreasing

Oil Eater Original Cleaner Degreaser

View On Amazon

This powerful cleaner is formulated to dissolve tough grease and oil on most surfaces, and it works exceptionally well on concrete. Oil Eater is suitable for home and commercial use, and it’s USDA-approved for use at food service facilities. This formula contains no harsh solvents, and it is noncorrosive and biodegradable. In addition to eradicating grease on concrete, it can be used to clean patios, driveways, grills, boat hulls, tires, and many other surfaces. 

Because Oil Eater is ultra-concentrated, it will need to be diluted before use. Depending on the ratio of water, it can be used as light, medium, or heavy-duty degreaser. (Refer to the dilution chart on the label to determine the appropriate amount.) This product can be applied with a brush, broom, or pressure washer. Once you’ve worked the cleaner into the stained surface, let it sit for five minutes and then thoroughly rinse it off with a hose. While it removes grease stains almost immediately, it may have more difficulty removing oil stains.

Best for Rust

Iron-Out Outdoor Rust Stain Remover

View On Amazon

This liquid formula from Iron OUT is highly effective at removing rust stains from outdoor surfaces. Despite being a professional grade rust remover,  it can be easily applied with a tank sprayer, cloth, or roller. Because the solution is pre-mixed, it doesn’t need to be diluted, and we love how it dissolves stains almost instantly without scrubbing. Once it’s applied, however, the instructions say to rinse it off immediately. (You should wear gloves as you are working, too.)

Iron OUT is a highly versatile formula that can be used on a variety of outdoor surfaces, including exterior walls, sidewalks, driveways, fences, and decks. Because it's also safe to use around plants and grass, accidental overspray won’t cause any harm. It’s important to note that this product may have a bleaching effect. It may leave white spots behind, particularly on concrete surfaces, so be sure to test first.

Best Eco-Friendly

ACT Concrete Cleaner

View On Amazon

While the majority of concrete cleaners are chemical-based, ACT offers an environmentally friendly formula that’s safe to use around children, animals, and plants. Using a process known as bioremediation, this product contains microbes that naturally break down and effectively eliminate stains. ACT Concrete Cleaner can be used on a variety of surfaces, including cement driveways, patios, and decks. We love that it won’t remove paint. 

This powder formula can be easily applied with a broom. One pound will cover approximately 100 square feet. All you need to do is work it into the stained surface, mist the applied product with a spray bottle, and let it sit. There is no need to sweep or wash it off afterwards. The only drawback is that it takes two to four weeks to completely remove stubborn stains. However, misting and adding more cleaner can speed up the process. ACT Concrete Cleaner is significantly pricer than other options, but is an eco-friendly option.
