The easiest way to clean concrete floors is to use solutions that are specifically designed for concrete floors. Because no two concrete floors are the same, each requires a different maintenance approach.

You wouldn’t clean floors in your polished and sealed living room the same way you would clean a concrete garage floor. We’ve got some great advice on how to clean concrete floors you’ve always wanted.

Differences Between Concrete And Cement Floors

The terms “concrete” and “cement” are sometimes used interchangeably, yet they refer to two distinct materials. There is, in fact, nothing called a concrete floor.


In concrete construction, cement is a fine powder formed of crushed minerals and stones. Despite the fact that cement can be used for a variety of purposes, it isn’t strong enough to be used for flooring.

Concrete is made of cement, water, and any type of aggregates such as crushed sandstone, gravel, and more. The wet cement acts as a glue that holds everything together during the curing process.

Two Most Common Options That Can Help To Clean Concrete

Cement Floor Cleaner

Polished concrete floors are the most durable, despite the fact that concrete floors in general are. In contrast to a glazed or sealed floor, which must be sealed and resealed to avoid deterioration, a well-maintained shiny concrete floor needs just regular care.

A concrete floor’s brilliant shine can be ruined if it’s covered with the kind of gritty particles and filth that can damage the surface.

There’s no need to purchase a dedicated cleaner, although you can find such goods in hardware stores if you do so. Instead, you can use household chemicals to clean and polish your concrete floor.

Concrete floor stains may be an exception to this rule. Finding the cause of the stain is the most effective technique to remove it from discolored concrete floors.

Commercial stain removers are available for the majority of common blemish types. Bleach or ammonia can be used instead to avoid the toxic fumes produced by professional floor cleaners. However, mixing these two cleaning products can result in a dangerous reaction.

You’ll probably need to polish the concrete flooring after you’ve cleaned them. Once every two years, you only need to polish your concrete to give it a beautiful glow and keep it from becoming too shiny.

Using a floor cleaner or a concrete polisher is considerably easier than using a buffing chemical and a microfiber cloth. Concrete polishers can be rented, or the operation can be contracted out to a concrete contractor.

Either way, it’s a relatively straightforward process. The first step is to fill in all cracks with epoxy or some other caulk that expands and fills the gaps.

After that, use a sander with a coarse abrasive to polish the floor. Abrasives of increasing fineness and decreasing coarseness should be used to refine the sanding process until the desired result is achieved. When the polishing is done, use a floor polish and let it dry.

Products You Can Use

When cleaning a concrete floor, it is crucial to know what finish it has so that you can use the correct cleaning chemicals and instruments for the job.

Generally, a pH-neutral cleaner is needed to remove stains from waxed or sealed concrete and restore its appearance. It is important to avoid harsh cleaning solutions or products such as lemon extract, vinegar, ammonia, and bleach to avoid damaging concrete.

When cleaning concrete floors in general, dust mops, brooms, and vacuums are all excellent options. Most of all, concrete flooring nowadays is either sealed or waxed, but we offer solutions for both types of unfinished concrete.

Types Of Cleaning Concrete Or Cement

Whatever the problem, the best way to clean it will vary depending on the situation. Having many stains on your cement or concrete will necessitate a distinct treatment for each.

Before You Start

Removing stains from a soiled cement or concrete floor takes time and effort, but it is not impossible. There are a few things to keep in mind before you get started:

Do not mix different cleaning methods. Toxic gases and other health issues might result from mixing different solvents. Give the floor ample time to dry between each stain removal procedure, then repeat the process for each stain type.

Good ventilation is essential. Open the garage doors if you’re working there. You should open the windows if you’re working in an enclosed space. Irritating dust and other contaminants will be released into the air as a result of your work.

Ensure the health of your lungs by taking the necessary precautions. Wearing a mask is also a good idea if you suffer from allergies or asthma.

Dirty Cement Simple Cleaning

Cleaning the entire surface should be done before attempting to remove cement stains.

  1. Debris can be removed by using a push broom on the surface.
  2. Half a cup of baking soda, one gallon of lukewarm water, and enough liquid dish soap go into a bucket. Spread it throughout and scrape dirty areas with a hard brush or a push broom. Let it air dry after rinsing.
  3. Rewet the area and apply oxygenated bleach for stubborn stains. There is no risk of damaging your lawn or driveway using oxygen bleach, unlike chlorinated bleach. Scrub the area once more with the broom’s bristles, then leave the oxygenated bleach on for 10-15 minutes to do its work.
  4. Then, use clean water to thoroughly clean the area and your broom. Both should be allowed to air dry completely.

Removing Mildew, Mold, Or Moss

Mold, moss, and cement cannot be removed from organic materials simply by sweeping. Cleaning mold stains from cement requires killing the spores that are responsible for the discoloration.

  1. Mix equal quantities of hot water and distilled vinegar and apply to the moss stain on your cement.
  2. After spraying, use the push broom to thoroughly clean the area.
  3. Allow the area to dry thoroughly after rinsing with fresh water.

Make a solution of oxygenated bleach and hot water in a 1.4:1 ratio to remove very persistent mold or mildew stains from cement.

Grease Stains

If you have a concrete floor, you may want to keep an eye out for oil stains caused by lawnmowers, cars, or other machinery. Because cement is porous, you can discover that the oily sludge has penetrated deep into the surface, leaving a permanent mark.

Getting rid of these oily cement stains can be done, but patience is required. In other words, elbow grease is the most excellent technique to remove grease stains from your cement. Here are the steps:

  1. Sprinkle cornstarch, baby powder, clay, diatomaceous earth, cat litter, on the spilled area to soak it up. They’re all incredibly absorbent and can remove oily smears from cement with ease. You’ll need about a half-inch thick coating, though.
  2. To remove the oil, leave the powder in place for at least 24 hours. Keep an eye on it and add more powder if the top layer begins to show signs of greasy buildup. Sweep up and dispose of the mess at the end of the day.
  3. Pour 1 quart of hot water with 1 teaspoon of liquid dish soap into a bucket, and mix thoroughly.
  4. Using a brush or broom, scrape the mixture into place. After thorough rinsing in hot water, allow it to air dry.

Rust Stains

You can use white vinegar to rub with a hard brush to remove rust stains from cement that are still fresh. To avoid etching, use fresh water to rinse the area thoroughly after using an undiluted vinegar solution.

When dealing with older or larger rust stains, dampen the area and then sprinkle it with oxalic acid. Mild enough that it cannot create scratches on concrete, yet with the capability to dissolve rust. Scrub the stain thoroughly using a stiff brush, and then rinse thoroughly.

Special Cleaning Method For Sealed Concrete

Cleaning concrete can be difficult because grout lines, fissures, and/or saw cuts can collect dirt and bacteria, making for an ugly appearance.

As a result, it’s critical to look for and remove any visible dirt lines on the floor. In either case, it’s best to do it just after you’ve finished cleaning the remaining floor; otherwise, some of the dirt will be removed during your usual sweeping and mopping.

This makes it simple to spot-clean the fine lines. Concrete floor cracks and saw cuts can be cleaned with an old brush and a less powerful cleaner. Using the procedures below, you can clean the remaining floor thoroughly to remove grime and stains.

  1. To begin, use a static broom or a microfibre dust mop to remove any dust or debris from the surface. The effectiveness of this particular cleaning equipment in removing dust explains why they are recommended. For those who don’t have a proper brush with long bristles to cover the metal section or beater bar of the vacuum cleaner, it is strongly recommended not to use this method because it can leave scratches on the concrete finish.
  2. Moisture should be kept to a minimum even while using a pH-neutral cleanser. Use a damp microfiber cloth and a mild cleaner to clean your concrete floor on a weekly basis. Dust and debris should be vacuumed off your concrete floor every day, and stains and marks should be cleaned using a moist mop.
  3. The stained concrete floor will require periodic buffing to restore its former luster. Depending on the sort of finish you have, a commercial product is recommended for this task.

  2. Start with a moderate cleaning agent like a pH-neutral product and a non-wired brush to remove stains from unfinished concrete. Apply the cleanser and rub in circular motions to the stained area. If necessary, repeat the process when the floor has completely dried.
  3. There may be times when industrial stain removers like bleach or degreaser are needed to remove stains that have been there for some time.
