1. Use a Dust Mop or Broom to Remove Dust and Dirt Particles
Before you start cleaning the spills and stains on your polished concrete floor, it’s important to remove any loose dirt and dust.
This can be easily done by using a dust mop or a soft-bristle broom. Simply sweep the surface of the floor, ensuring that you reach all corners and edges.
2. Clean the Floor’s Surface with a Vacuum
In addition to using a dust mop or broom, it’s recommended to vacuum the polished concrete floor regularly. A vacuum cleaner with a soft brush attachment can effectively remove any remaining dirt and debris that may have been missed during sweeping. By vacuuming the surface, you ensure a clean starting point for the stain removal process.
3. Dampen the Polished Concrete Floor with a Mild Cleaning Solution
Once the loose dirt and dust have been removed, it’s time to damp-mop the polished concrete floor. Fill a bucket with warm water and add a mild cleaning solution specifically designed for polished concrete floors.
Avoid using harsh chemicals or abrasive cleaners, as they can damage the surface of the concrete.
Wet a mop in the cleaning solution and wring out any excess water. Then, mop the floor in a gentle circular motion, ensuring that the entire surface is covered.
4. Eliminate Tough Stains Using Baking Soda
If you encounter a tough stain on your polished concrete floor, such as oil or acidic stains, baking soda can be an effective solution. Baking soda acts as a gentle abrasive and can help lift the stain without causing damage to the concrete.
To remove the stain, create a paste by mixing baking soda with water. Apply the paste directly to the stained area and let it sit for about 15 minutes.
Then, scrub the stained area using a soft brush or a non-abrasive sponge. Rinse the area with clean water and repeat the process if necessary.
Baking soda is particularly useful for oil stains and can help absorb the oil from the surface of the concrete.
5. Dry the floor with a microfiber cloth or soft towel.
After cleaning the polished concrete floor, it’s important to dry it thoroughly to prevent any water stains or damage. Use a soft towel or a microfiber cloth to absorb the moisture from the surface of the floor.
Ensure that the floor is completely dry before stepping on it or placing any furniture back in its place.
This step not only prevents water stains but also helps maintain the shiny appearance of the polished concrete.
6. Seal Your Concrete Floors
To further protect your polished concrete floors from spills and stains, consider sealing them. Concrete sealers act as a barrier against liquids, preventing them from penetrating the surface and causing stains.
There are various types of concrete sealers available, including topical sealers and penetrating sealers.
Topical sealers create a thin protective layer on top of the concrete, while penetrating sealers penetrate the concrete, providing long-lasting protection.
Consult a professional or refer to the manufacturer’s instructions to choose the most suitable sealer for your polished concrete floor.

Can you use bleach and ammonia on polished concrete?
While bleach and ammonia are strong cleaning agents, they’re not suitable for polished concrete floors. Here’s why:
- Damage to sealant: Bleach can break down the sealant on your polished concrete, making it vulnerable to staining and etching. This can lead to the need for costly repairs.
- Discoloration: Bleach can cause discoloration and yellowing, especially on darker shades of polished concrete.
- Fumes: Bleach emits harmful fumes, especially when mixed with other cleaning products. Inhaling these fumes can irritate your eyes, nose, and lungs.
- Etching: Ammonia is highly alkaline and can etch the surface of your polished concrete, leaving it dull and rough.
- Fumes: Like bleach, ammonia also emits strong fumes that can be harmful if inhaled.
- Slippery surface: Ammonia can leave a residue on your floors, making them slippery and dangerous.
Can you do steam cleaning on polished concrete?
No, it is not recommended to use a steam cleaner on polished concrete floors. The high heat and moisture from the steam can cause the surface to erode over time, leading to cracks and dullness.
Additionally, the steam can also damage the sealant that protects the polished concrete.
