How to remove stains from Polished Concrete Floors

Polished concrete floors are exceptionally durable due to the densification and polishing process.

Because they don’t require sealers or waxes, they’re often easier to maintain than other forms of decorative concrete floors. Polished concrete should last for years if you follow this simple cleaning routine.

To remove stains from polished concrete, use a dry dust mop. Damp-mop with a pH-neutral cleaner or special cleaners and conditioners regularly make for polished concrete. These cleaners don’t just clean the surface; they also leave a dirt-resistant coating behind. They don’t require buffing and can be applied with a mop.

If the floor loses its luster over time, just buffing it with a commercial polishing chemical will usually restore it. If an extra touch-up is required, the floors can be softly re-polished with a fine-grit abrasive.

What and Cleaners Should I use on Concrete Floors?

For decorative concrete floors, a pH-neutral cleanser is preferable. You’ve to enquire from your contractor or the wax or the sealer maker to propose their best cleaning solutions.

Avoid harsh cleaning agents like ammonia, lemon, bleach, vinegar, or pine cleansers on concrete since they might etch the surface. Find out more about how to choose a concrete cleaner.

Both dry and damp mopping should be done with microfiber cleaning pads.

Equipment such as an auto scrubber or a swing buffer can be employed in high-traffic business areas.

A steam mop can be used to clean concrete floors without chemicals.

Use warm water and dish soap to remove stubborn stains, then scrub with a bristle brush (use a degreaser if necessary)

On larger tasks, a wet vac can help remove extra water.

How to Clean Plain Concrete Floors

Using a brush, a blower, or a garden hose, clean the surface of dust and debris.

A soft (non-metal) scrub brush and warm water should be used initially to remove stains. Gradually increase the strength of the soap, then add ammonia.

Chemicals or degreasers may be required to remove stubborn stains. (which only should be utilized on plain concrete; they should not be used on stained or polished concrete.)

Exterior or semi-exterior surfaces, such as garages, can be power washed.

After thorough washing, seal the concrete to make the next cycle much more effortless.

If you plan on staining the concrete in the future, don’t use muriatic acid to clean it.

How to Clean Stained Concrete Floor


In most circumstances, stained concrete floors get little foot traffic and are relatively easy to clean.

Regularly dust mop or damp mop to remove dirt and grime and reduce abrasion. For a deeper cleaning, damp mop with a pH-neutral cleaner and water.

Use an excellent film-forming sealer and a layer of wax or floor finish to protect it. Reapply as needed, usually every several years, depending on wear.

Follow the same procedure for stained floors in commercial settings; however, more frequent application of protective wax is required due to more significant foot activity.


A proper floor sealer should always protect stained floors from water, filth, stains, and abrasion. This top layer of protection not only extends the life of your floor but can also add sheen and improve the color.


Many contractors advocate putting an excellent commercial-grade floor wax made for concrete floors on top of the sealer for added protection against stains, filth, and abrasion. By bearing the brunt of regular wear and strain, this layer aids in preserving the sealer.

Repairs to Concrete Floors


In the event your concrete floor has minor scratches, cracks, or gouges, don’t fret, as these types of flaws can always mostly be repaired with the appropriate patching material.

If the damages are more severe, the floor would require resurfacing with an overlay. Sometimes, it’s attainable to highlight existing floor cracks to make them look like part of the original floor design by staining, saw cutting, and other techniques.

Fixing Discoloration

Minor cracks, scratches, or gouges in your concrete floor may nearly always be repaired with the appropriate patching material.

The floor might require replacing an overlay if the cracking is more severe or widespread. Through staining, saw cutting, and other procedures, it is sometimes feasible to enhance existing floor fissures and make them part of the floor design.

When correctly applied, concrete floor stains and dyes penetrate deeply into the surface, providing permanent color that won’t flake, peel, or fade.

On the other hand, acid stains react chemically with the concrete and can be fickle and generate unexpected color fluctuations.

If the floor isn’t covered with a sealer or floor wax, stains from spills or other incidents may be absorbed into the concrete.

You may fix floor stains and discoloration in various ways, from applying a tinted sealer to completely changing the color with a fresh coat of dye or concrete stain.
