White, chalky deposits on brick, concrete blocks, pavers and masonry façades can quickly make a clean building look old and poorly maintained. These deposits are commonly known as efflorescence.
Although light surface deposits may sometimes be brushed away, stubborn or recurring efflorescence usually requires a professional masonry-cleaning method. For contractors, property managers, municipalities and restoration specialists, FORCE Concentrated Industrial Acid Cleaner – 20 L is a powerful professional option for removing efflorescence and restoring masonry surfaces.
Available from 1001 Produits et Services d’Entretien, FORCE is a concentrated, biodegradable, professional-grade masonry cleaner designed for demanding construction, building-maintenance and restoration projects.
What Is Efflorescence?
Efflorescence is a crystalline deposit of soluble salts that appears on porous construction materials. It is commonly white but may occasionally appear yellowish or brown, depending on the minerals and contaminants present.
Efflorescence generally requires three elements:
- Soluble salts within the brick, mortar, concrete or surrounding materials
- Moisture entering or moving through the masonry
- A porous surface through which the moisture can travel
As water moves through the masonry, it dissolves salts contained in the building materials. When that water reaches the surface and evaporates, the salts remain behind as a visible powdery or crystalline deposit.
Efflorescence may appear on:
- Red clay brick
- Concrete brick and block
- Mortar joints
- Concrete foundations
- Retaining walls
- Pavers
- Commercial and institutional façades
- Newly constructed masonry
- Older buildings affected by water infiltration
Why Does Efflorescence Keep Coming Back?
Cleaning the visible deposits is only part of the solution. If efflorescence returns repeatedly, there may be an ongoing source of moisture behind or around the masonry.
Common moisture sources include:
- Defective gutters or downspouts
- Improper flashing
- Cracks around windows and doors
- Sprinklers directed toward the building
- Poor site drainage
- Rising ground moisture
- Water entering through damaged mortar joints
- Insufficient protection at the top of a wall
Industry guidance recommends correcting moisture-entry problems and allowing the masonry to dry before attempting to remove the deposits. Persistent efflorescence may indicate continued water intrusion and should not be treated as only a cosmetic issue.
Why Ordinary Pressure Washing May Not Be Enough
Fresh, powdery efflorescence can sometimes be removed with a dry, stiff fibre brush. Water rinsing may also dissolve light salt deposits.
However, water can temporarily dissolve the salts and carry them back into the masonry. As the surface dries, the salts may migrate outward again and produce another visible deposit.
Heavy, hardened or deeply established efflorescence may therefore require a proprietary professional masonry cleaner. The Brick Industry Association recommends using an appropriate formulated cleaner for stubborn deposits and carefully following the manufacturer’s instructions.
Increasing water pressure is not necessarily the solution. Excessive pressure can damage brick surfaces, erode mortar joints and alter the appearance of the façade. The goal should be to let the appropriate cleaning product loosen and dissolve the contamination rather than attempting to blast it away mechanically.

FORCE Concentrated Industrial Acid Cleaner is designed for intensive masonry and façade restoration.
Its concentrated professional formula helps remove:
- Efflorescence
- Cement residue
- Mortar and construction deposits
- Rust stains
- Mineral accumulation
- Organic atmospheric pollution
- Heavy contamination on compatible masonry surfaces
FORCE is supplied in a concentrated 20-litre format, making it a practical solution for contractors and professionals working on large walls, commercial properties, institutional buildings and restoration projects. The product was previously sold under the name TARTROX.
Why FORCE Is a Leading Professional Choice in Quebec and Canada
No single acidic cleaner is appropriate for every type of stone, brick or architectural surface. However, FORCE stands out as one of our strongest professional masonry-cleaning options for compatible surfaces.
Professional-strength performance
FORCE is formulated for intensive work rather than routine household cleaning. It is suitable for projects where ordinary detergents, brushing or water rinsing cannot fully remove mineral and construction-related deposits.
Concentrated 20-litre format
Because FORCE is concentrated and may be diluted according to the surface, contamination and manufacturer’s directions, one container can cover substantial project areas.
This makes it especially practical for:
- Masonry contractors
- General contractors
- Commercial cleaning companies
- Building-restoration specialists
- Property-management companies
- Municipal maintenance departments
- Industrial facilities
More than an efflorescence remover
Some products are designed only for light white deposits. FORCE provides broader professional cleaning capabilities by also targeting cement residue, rust staining and atmospheric contamination on compatible masonry surfaces.
Professional guidance from a Canadian supplier
1001 Produits et Services d’Entretien has more than 30 years of experience supplying professional cleaning, maintenance and masonry products. Customers can obtain assistance with product selection, project quantities and professional applications rather than purchasing an unidentified generic acid without support.
The Professional Method for Removing Efflorescence
The correct procedure depends on the type of masonry, the condition of the wall and the severity of the deposits. Always consult the current product label, technical information and safety data sheet before starting.
1. Confirm that the deposit is efflorescence
Efflorescence is generally dry, crystalline and powdery. It should not be confused with:
- Mortar smears
- Lime runs
- Calcium deposits
- White scum
- Paint residue
- Mould
- Rust
- Vanadium or manganese staining
Applying an acidic cleaner without correctly identifying the stain can create an unexpected reaction or make the discolouration more difficult to correct.
2. Identify and correct the moisture source
Inspect the wall, roofline, gutters, flashings, windows, joints and surrounding drainage.
Removing the visible salts without addressing the water source may produce only temporary results. Allow the wall to dry after correcting the moisture problem.
3. Dry-brush loose deposits
Before applying a liquid cleaner, remove as much loose material as possible with a stiff, non-metallic fibre brush.
Avoid steel-wire brushes. Metal particles left behind on the wall may rust and create additional staining.
Dry brushing also prevents unnecessary product use when part of the deposit can be removed mechanically.
4. Perform a test area
Always test FORCE in a small, inconspicuous section before treating the entire wall.
The test should confirm:
- Surface compatibility
- Appropriate dilution
- Required contact time
- Effect on the brick colour
- Effect on the mortar joints
- Final appearance after drying
- Whether a second treatment will be required
Because bricks, stones, concrete products and mortars vary considerably, a cleaner that performs well on one wall may react differently on another. Professional masonry guidance consistently recommends test-cleaning a representative section before beginning the complete project.
5. Protect surrounding materials
Before applying an acid-based cleaner, protect adjacent surfaces, including:
- Windows
- Doors
- Metal fixtures
- Painted surfaces
- Vehicles
- Plants and landscaping
- Nearby walls and flooring
- Areas exposed to runoff
Use appropriate personal protective equipment and follow the product’s safety data sheet. Acidic masonry cleaners are professional chemical products and must be handled, stored and applied with the appropriate precautions.
6. Prepare and dilute FORCE correctly
Dilute FORCE only according to the current product instructions and the results of the test area.
Do not assume that a stronger solution will produce a better result. An unnecessarily aggressive mixture may affect the colour or surface of the masonry and mortar.
Use clean, acid-compatible application equipment. Never combine FORCE with bleach, alkaline chemicals or another cleaning product.
7. Apply in small, controlled sections
Apply the prepared solution uniformly to a manageable section of the wall.
Working in smaller areas helps:
- Maintain a consistent contact time
- Prevent the solution from drying
- Reduce streaking
- Control runoff
- Produce a more uniform finish
Do not allow the cleaning solution to dry on the masonry. Hot, sunny or windy conditions may shorten the working time considerably.
8. Agitate stubborn deposits when appropriate
Where permitted by the product directions and test results, a non-metallic masonry brush can help loosen heavy crystalline deposits.
Avoid aggressive scraping and abrasive blasting. Abrasive methods can remove the outer surface of brick and mortar, permanently changing the texture and increasing future water penetration.
9. Rinse thoroughly
After the recommended contact time, rinse the masonry thoroughly with clean water.
Insufficient rinsing may leave chemical or dissolved mineral residue behind. Use controlled water flow and the gentlest effective pressure.
High-pressure cleaning should not be used as a substitute for proper chemical action. Excessive pressure can erode mortar joints and damage brick surfaces.
10. Let the masonry dry before evaluating it
Wet masonry normally appears darker, so the final result should not be judged immediately after rinsing.
Allow the cleaned section to dry completely. If deposits remain, a second controlled treatment may be preferable to one excessively aggressive application.
What Should You Avoid When Cleaning Efflorescence?
Do not use untreated muriatic acid
Raw muriatic acid can be unpredictable and difficult to control. It may burn or discolour brick, etch mortar joints and cause additional staining.
A formulated proprietary masonry cleaner offers more consistent performance than a job-site acid mixture.
Do not rely on excessive pressure
Pressure alone may damage the surface without removing the salts responsible for the deposit.
Do not sandblast brick
Sandblasting and other aggressive abrasive methods can remove the protective outer surface of masonry and permanently damage both brick and mortar.
Do not skip the test area
Different bricks and mortars can react differently to acidic cleaners. Testing is one of the most important steps in any professional masonry-cleaning project.
Do not ignore recurring moisture
When efflorescence repeatedly returns, investigate the wall assembly and surrounding drainage before continuing to clean it.
Ideal Applications for FORCE
FORCE can be considered for compatible masonry-cleaning projects such as:
- Brick façades
- Concrete-block walls
- Commercial buildings
- Warehouses and industrial facilities
- Institutional properties
- Municipal buildings
- Retaining walls
