How to Clean Concrete Floors

Until now, you may have believed that concrete is exclusively used as a flooring material in garages, parking areas, driveways, and commercial establishments. However, concrete is also used for indoor flooring in residential and office settings.

In today's fast-paced lifestyle, where individuals rarely have time to clean their tiled or marble floors thoroughly, concrete has emerged as a practical and worthwhile investment. Nonetheless, this doesn't imply that concrete flooring requires no maintenance. On the contrary, to preserve the desirable qualities of concrete floors, individuals need to exercise caution when selecting cleaning methods and choosing suitable cleaners.

When it comes to cleaning concrete outdoors, a power washer proves to be the most convenient option. With this tool, you can effectively remove dirt, mildew, and grime in a single afternoon. Renting a power washer and carefully following the instructions for its usage is crucial. 

Start by spraying the surface of the patio with a detergent and scrubbing it into the concrete with a stiff brush. Don't use a brush with metal bristles, because the metal fibres can get stuck in the pores of the concrete and cause it to rust. Before cleaning, ensure you put on safety goggles and gloves for protection. Once the pressure washer is turned on, move the wand from one side to the other, employing a motion similar to mopping a floor.

Cleaning Concrete Floors

While the concrete was once primarily used for outdoor purposes such as patios, sidewalks, driveways, basements, and garages, it has now gained popularity as a sophisticated option for indoor floors and countertops. Concrete is highly regarded for its exceptional durability. However, like any surface, it can accumulate dust, debris, and spills over time, requiring regular cleaning to keep it in optimal condition. In addition, unsealed concrete is particularly vulnerable to degradation when rust or mould penetrates its surface. Fortunately, maintaining and caring for concrete floors is relatively easy with routine cleaning.

Proper care is especially important for resurfaced concrete floors to ensure long-term preservation. Whether you're cleaning a finished concrete floor inside your home, refreshing unsealed concrete on your patio, or dealing with stubborn stains in your garage, simple solutions are available to restore the appearance of concrete and make it look brand new.

However, it's important to note that concrete is not completely immune to stains and will require periodic cleaning. So whether embarking on a spring cleaning spree or tackling a challenging stain, knowing how to clean concrete floors properly is essential to achieve the best possible results.

Before You Begin

To ensure the protection and effective cleaning of your concrete floors, it is important to understand the type of finish applied to the concrete. In addition, promptly cleaning and treating stains and spills is crucial. Here are some common concrete floor treatments found in homes:

Painted

Although concrete is susceptible to staining, achieving a long-lasting surface with oil-based or latex paint can be challenging. If the concrete surface has been polished or sealed, the paint will need help to adhere properly, leading to peeling and poor durability.

Polished

Concrete can be polished using wet or dry methods to achieve a lustrous finish that doesn't require waxing or recoating. The desired level of shine can be selected, and the concrete can also be stained to resemble the appearance of marble, granite, or other polished stones.

Stained

For those who prefer a different colour than grey, various stains are available in a wide range of colours to enhance newly poured or existing concrete. These stains deeply penetrate the concrete and provide a permanent colour transformation. After staining, the concrete can be sealed for added protection or left unsealed, depending on the desired finish.

Unsealed

When concrete is poured without any additional treatment, it remains unsealed. This means the surface retains its natural porosity, making it prone to staining, especially from liquids like oil.

Steps for Cleaning Concrete

Remove Loose Dirt and Debris

Remove loose dirt from the surface of your concrete by sweeping or vacuuming unless you're dealing with a mould or mildew issue in your basement. In that case, follow the instructions below to address these potential household toxins.

Remove any weeds that have grown in the cracks of a patio or driveway and treat them as needed.

Mix a Cleaning Solution and Mop

In a bucket or sink, mix 2 gallons of warm water with 2 teaspoons of dish soap to make a cleaning solution. Use this solution to mop the concrete floor. Avoid harsh cleaners that can potentially damage and diminish the sealant's effectiveness. Follow the recommendations of the installer regarding the resealing process.

Spot Treat Stains

You can use a mixture of liquid laundry detergent and water to treat stains without breaking the bank. First, focus on the stained area by directly pouring the detergent onto the stain. Then, use a stiff nylon brush to scrub the area, avoiding wire-bristle brushes as they can potentially scratch the concrete surface. Finally, rinse the area with water and allow it to dry. This cost-effective method can help remove stains and restore the appearance of the concrete.

Repeat if Necessary

If the stain persists and doesn't disappear with the previous cleaning solution, you can enhance your cleaning mixture by combining white vinegar and water or baking soda and water. Apply this solution to the stain and scrub the area again. Finally, rinse the area thoroughly with a bucket of water or a garden hose to remove any residue. This method can provide an extra boost to tackle stubborn stains on your concrete surface.

Rinse and Dry

After cleaning, it's important to rinse the floor to remove any remaining soapy residue. Next, return over the floor with clean water and a wet mop, ensuring the soap is thoroughly washed away. Next, allow the floor to air-dry naturally, allowing any excess water to evaporate. This step will leave your concrete floor clean and free of any cleaning solution residue.

How to Remove Stains From Concrete

Cleaning concrete floors with tough stains is possible in a number of ways. Depending on the substance spilt and the flooring's current condition, a specific method should be selected.

Flour and hydrogen peroxide can be mixed to make a paste that can be used to remove stains from interior concrete using a more natural approach. After applying the paste to the stained area, you should let it sit overnight before scraping it off with a plastic-edged scraper.

Stains can be easily removed with a solution of trisodium phosphate (TSP) and water. Use a nylon bristle brush to remove the stain, and then rinse the area thoroughly with water from the hose. You can find TSP at any hardware or home improvement store.

Muriatic acid is useful for removing rust and dried grout from outdoor floors. When working with this potent toxin, however, caution is essential. Always follow the manufacturer's instructions when using muriatic acid to clean concrete, and always wear protective eyewear and gloves.

Care must be taken when cleaning indoor polished or stamped concrete floors. Mop the floor using a solution of water and a gentle cleaner such as Castile soap, liquid dish detergent, stone cleaner, or moderate floor cleaner. Mop the floor with the solution, and then wipe it down with a fresh water mop. Floors that have been polished or stamped should not be cleaned with ammonia, bleach, or other harsh chemicals.

For the best results and to prevent damage to your concrete floors, always follow the recommended cleaning instructions and safety precautions.

The following are some tried-and-true methods for removing stains from concrete floors:

• Cornflour or dry kitty litter can be used to absorb oil and grease stains when applied as a thin layer. You should give the oil time to soak in, ideally for three days. Concrete that hasn't been sealed is porous, so oil needs time to seep into the base. Clear the area using a vacuum cleaner, and repeat if necessary.
• To remove stains from food and drinks, combine 1 quart of water with 2 tablespoons of dish soap. Apply the concoction using a stiff brush and thoroughly scrub the area. Oily areas require liquid application and scrubbing. Thoroughly clean it with just water.
• In order to remove tyre tracks, first wet the area and then use a degreaser. You should wait at least four hours after applying the cleaner before scrubbing it with a stiff brush. Please thoroughly rinse.
• White vinegar can be used to remove light rust stains from concrete; simply pour it on the stains and let it sit for at least 30 minutes. Scrub it with a stiff brush, and then wash it thoroughly. If the stains are particularly large and dark, use a commercial rust remover containing oxalic acid.
• To eliminate mildew stains, mix 1 quart of water with 2 tablespoons of powdered laundry detergent and 2 tablespoons of trisodium phosphate (TSP). Rubber gloves are a must for safety. Using the cleaning solution and the bristled brush, thoroughly scrub the mouldy area, and then rinse. The combination of chlorine bleach and water is effective in removing stubborn mildew stains. Use a stiff brush and a solution of one cup of bleach per gallon of water to clean the area, then give it a final scrub and rinse.

Unsealed Concrete Floor Cleaning Procedures

Unsealed concrete is porous and easily stained or worn down. Therefore, it is essential to clean up spills on the floor as soon as possible to avoid staining. Use a wet rag to wipe up any spills right away.

The same method should be used on a regular basis to clean sealed concrete floors. The first step in cleaning is to sweep or vacuum the floor. Then, using one gallon of hot water and one eighth of a cup of mild dish soap, mop the floor. You should mop the floor and then rinse it with clean water and let it dry naturally.

Stains and messes that refuse to go away take more work to clean up. Most stains, alas, are not washable. However, before resorting to more extreme measures, you can try removing them with dish soap and hot (or boiling) water and a stiff-bristled nylon brush.

If the dishwashing liquid and water solution doesn't work, the concrete will need to be cleaned. To begin, make a smooth paste by combining trisodium phosphate (TSP), water, and an absorbent substance such as kitty litter or sawdust. Spread the paste over the stained area and wait for it to dry. Once the paste has dried, it can be swept or vacuumed away. One treatment may not be enough to completely remove the stain, so you may need to be patient and give it another try.

TSP should be used with caution. Put on some gloves and a long-sleeved shirt, and think about grabbing a pair of safety goggles and a face mask, too. If you must use TSP indoors, make sure there is adequate ventilation. Be cautious around glass, metal, ceramic tile, grout, and other surfaces that are vulnerable to TSP's corrosive effects. Checking the rules in your area is also recommended because TSP use may be limited by local regulations.

Pre-mixed concrete stain removers are another option; just make sure to read the label and use the product as directed. Again, it's best to test cleaning products on a small, hidden section of flooring before tackling larger, more obvious messes.
