How to Clean Pavers with Mariatic Acid | A Detail Guide By Expert

This article’s primary objective is to educate us on how to clean pavers with muriatic acid and other topics discussed in the context of the article.

The muriatic acid, also called strong water or hydrochloric acid, is a chemical normally used for cleaning hard surfaces and hard to clean, as is the case of brick, concrete, among others. It is a highly corrosive product that must be used with extreme care; otherwise, it could cause damage to our skin or objects in our home.

How to Clean Pavers with Mariatic Acid

Sometimes when pavers are installed on a walkway or patio area, the mortar is not completely wiped off and dries on the surface to be paved. This creates an oil stain that doesn’t come off no matter how hard you rub it or what type of cleaning solution you use. In these cases, muriatic acid wash is necessary to dissolve the mortar. Muriatic Acid washes also remove stubborn stains that do not respond to other cleaning methods.


  • Ensure you use a small amount of powdered lime sprinkle around the pavers’ edges in a continuous mound to flow with the acid as it runs away.
  • Put on disposable gloves, long sleeves and pants, and a face shield.
  • Fill a plastic bucket with a mixture of 1-part hydrochloric acid and ten parts water. Gently agitate the solution with a paint stirrer to mix it.
  • Wet the paver surface lightly with a garden hose until all top surfaces are wet.
  • Pour the mixture over the pavers’ stained areas and let it sit for five to 10 minutes.
  • Scrub the pavers with a long-handled brush, such as is used for washing cars. Continue rubbing until the stains are removed from the pavers.
  • Rinse the pavers thoroughly using a garden hose, directing water flow to the mounds of lime powder.
  • Use a shovel to scoop up the lime powder and place it in garbage bags for disposal. Contact your local sanitation department to locate the nearest hazardous waste disposal location and collect the bags for it.

How to Clean and Maintain Concrete Pavers

Solid pavers are mainstream and found in different open-air regions. Generally talking, they are truly tough and require little upkeep and support. Notwithstanding, you need to ensure you clean them well to keep them in great condition.

You should all the more adequately eliminate any development. Choose to use ice melt products because you feel there is too much snow to shovel, be aware that you will need to remove the puddles immediately afterward. Leaving a lot of liquid ice on the pavers for a generally extensive stretch will probably harm the pavers. You will also need to remove any sand or grit, and if mud develops, it is best washed off.

At the point when done, fill them with a reasonable grout. Smooth well and let dry. Then apply a sealer for better protection.

Products used to Clean Efflorescence from Concrete Pavers.

Efflorescence is the white powdery substance seen on the surface of brick and masonry walls and walkways. It comes from the water-soluble salts that leach out of brick, mortar, and grout when exposed to moisture. The salts settle on the surface and remain after the moisture evaporates, giving the brick a chalky appearance.

Chemical removal media

Several companies make products with their formulas to clean efflorescence. Some of the cleaning chemicals’ components are acid, detergent, bleach, solvents, and petroleum distillates. Cleaners can be labeled for multipurpose masonry, grout, and concrete cleaners effective for efflorescence, rust, and staining. There are several brands of efflorescence cleaners on the market now that are environmentally safe and biodegradable. Not all brands are environmentally safe, however, and some are dangerous and toxic. Make sure you read the labels carefully and follow all warnings and instructions carefully.

Muriatic acid

Washing the wall or hallway with muriatic acid mixed with water in a 1 part acid ratio to 12 parts water is a recommended last-resort solution to remove efflorescence. However, muriatic acid is a dangerous chemical that can cause serious injury and should be used with a thorough understanding of the product and safety procedures. Homeowners who like to do it themselves would do well to avoid using it.

Mechanical removal methods

Outdoor efflorescence can sometimes be removed by washing it with a garden hose with a high-pressure nozzle or a pressure washer. Scrubbing with a stiff, dry brush can also work, or you can try washing it with water and detergent or water mixed with vinegar. The efflorescence will eventually stop once all the salts have seeped from the brick and the brick dries completely. 

This is particularly true for interior bricks. If you want, wait and treat the symptoms for a few years. An aggressive way to remove efflorescence is with sandblasting, although it can damage the brick or binder.


Stopping moisture seeping through brick is a critical preventive measure. Once the brick is dry, apply masonry sealer to all exposed surfaces. If you have a brick wall that fills in with dirt, the problem of salt leaching through your brick may continue indefinitely, depositing and trapping the salts in the sealant. 

Trapped salts damage and deteriorate your masonry. Remove dirt behind the wall, seal the brick on all surfaces, and install a waterproof barrier. Similarly, a brick walkway on dirt or sand may have to be removed and a moisture barrier placed under it. Use low alkali cement and mortar when laying bricks to reduce efflorescence.

How to Clean Efflorescence on Concrete Paver

The first step to remove efflorescence is to let it dry. Next, you have to look for the causes and origin of the salts, and once the source of moisture has been eliminated, you can start treating. The previous step to eliminate efflorescence is to let it dry.

The simplest method is to dissolve the crystals with pressurized water and remove them with a natural bristle brush. To carry out this type of cleaning, choose a hot day so that the water evaporates and the surface remains dry. If not, the salts will dissolve back inside it. If the crystals do not dissolve with water, use a hydrochloric acid cleaner. Another less aggressive option with ceramic tiles is vinegar. Both products must be applied under pressure. When the salts recrystallize and harden, it is necessary to use metal bristles or electric brushes. Sometimes salts are found in solution in mortar or ceramic pieces. In these cases, the same rain and the passage of time make the crystals disappear.

To prevent efflorescence from coming out again, it is advisable to waterproof the affected area once treated.
