Prosoco Light Duty Concrete Cleaner

Prosoco Light Duty Concrete Cleaner – General Purpose Acidic Cleaner for New Construction Stain Removal

Prosoco Sure Klean Light Duty Concrete Cleaner is a specially formulated acidic cleaner designed to remove common construction and atmospheric staining from a wide range of masonry and concrete substrates. It is intended for contractors and trades professionals handling new construction cleanup, post-installation stain removal, and routine maintenance cleaning on architectural concrete, manufactured stone, decorative pavers, and more. The product removes rust, mud, atmospheric dirt, mortar smears, efflorescence, and other stains without altering surface texture, making it suitable for use on finished and decorative surfaces where appearance is critical. Supplied as a concentrate for on-site dilution, it offers flexibility and economy for large-scale jobsite application.

Unlike muriatic acid-based cleaners, Light Duty Concrete Cleaner contains no muriatic acid, reducing the risk of surface damage and worker exposure hazards associated with stronger acid formulations. It is safe for most pigmented concrete and colored mortar, and its water-rinsable formula makes cleanup straightforward on active job sites. The cleaner also improves color uniformity and enhances the appearance of treated substrates by adding depth to colors and brightening white matrices and exposed aggregate.

Key Features & Benefits

No Muriatic Acid Formula

Prosoco Light Duty Concrete Cleaner achieves effective stain removal without the hazards associated with muriatic acid, a common ingredient in competing products. This reduces worker exposure risk and minimizes the potential for unintended surface etching or discoloration. Contractors can use this product with greater confidence on finished architectural surfaces where muriatic acid would be too aggressive.

Multi-Substrate Compatibility

The cleaner is effective across a broad range of substrates, including smooth architectural and engineered concrete, custom masonry, concrete brick, manufactured stone, and decorative pavers. This versatility allows contractors to use a single product across multiple surface types on the same job site. Always test prior to full-scale application to confirm suitability and results.

Removes a Wide Range of Construction Stains

Light Duty Concrete Cleaner removes rust, mud, atmospheric dirt, mortar smears, efflorescence on brick and decorative pavers, secondary efflorescence on concrete block, and localized rust and metallic staining on unpolished limestone, travertine, and marble. This broad stain removal capability makes it a reliable general-purpose cleaner for new construction and post-installation cleanup scenarios.

Does Not Alter Surface Texture

The acidic cleaner is formulated to remove staining without etching or physically altering the surface texture of treated substrates. This is especially important on decorative and architectural surfaces where surface finish is part of the design specification. Contractors can clean aggressively without concern for texture damage when used as directed.

Concentrate for On-Site Dilution

Supplied as a concentrate, Light Duty Concrete Cleaner allows for on-site dilution to the appropriate strength for the task at hand. This reduces shipping weight and storage volume compared to pre-diluted products, offering cost efficiencies for contractors managing supply logistics on large projects. The product is water rinsable, requiring no special neutralization chemistry after use.

Improves Appearance and Color Uniformity

In addition to stain removal, the cleaner adds depth to colors, brightens white matrices, and enhances exposed aggregate finishes. This dual-function benefit means cleaned surfaces often exhibit improved aesthetic uniformity compared to pre-cleaning appearance, adding value beyond basic stain removal.

Common Applications

New Construction Cleanup

Removes mortar smears, construction soiling, and atmospheric staining from newly installed masonry, concrete, and stone surfaces. Best results are achieved when cleaning is performed within 7–28 days of installation depending on substrate type.

Efflorescence Removal on Brick and Pavers

Effectively removes primary and secondary efflorescence staining from brick, decorative pavers, and concrete block. Addresses both new construction efflorescence and atmospheric efflorescence that develops over time.

Rust and Metallic Stain Removal

Removes localized rust and other metallic staining on unpolished limestone, travertine, and marble. Always test prior to full application to confirm results and suitability on these substrates.

Concrete Brick and Manufactured Stone Cleaning

Removes mortar residues and construction soiling from concrete brick and manufactured stone within the recommended 7–14 day window after mortar joint tooling. Minimizes risk of accent color loss when used as directed with proper testing.

Atmospheric Dirt Removal

Removes atmospheric dirt and grime buildup from architectural concrete, custom masonry, and engineered concrete surfaces on both new and existing construction. Suitable for exterior cleaning applications on occupied buildings when proper precautions are taken.

Post-Installation Surface Preparation

Prepares masonry and concrete surfaces for subsequent sealing or protective coating applications by removing stains and residues that could interfere with adhesion or appearance. Cleaning before applying sealers or coatings improves final finish uniformity and long-term performance.

Application Instructions

Surface Preparation

1. Clean masonry before installing non-masonry materials such as windows, doors, finished flooring, metal fixtures, hardware, light fixtures, roofing materials, or any other materials that the cleaner could harm.
2. If cleaning must be completed after installation of non-masonry materials, test all adjacent substrates not intended to be treated before full-scale application. Protect untreated substrates from splash, residue, wind drift, and fumes using Sure Klean Strippable Masking or polyethylene sheeting.
3. Ensure all caulking and sealant materials are in place and thoroughly cured before cleaning begins.
4. When applying to the exteriors of occupied buildings, cover all windows, exterior intakes, and air conditioning vents, and shut down air handling equipment during application.
5. Protect open wall cavities from rain during construction to minimize moisture-related efflorescence staining.
6. When working over traffic areas, clean when traffic is at a minimum and protect or divert traffic as necessary.

Concrete Brick and Manufactured Stone

1. Remove mortar residues and construction soiling within 7–14 days of tooling the mortar joints.
2. Allow mortar and grout to cure at least 7 days before cleaning.
3. Minimize accumulation of excess mortar on the face of manufactured stone to limit potential for accent color loss during cleaning.
4. Avoid bonding agents where practical, as they make excess mortar more difficult to remove without loss of applied accent colors.
5. Clean carefully using fresh water and a soft brush during construction to manage mortar accumulation before chemical cleaning.
6. Always test the cleaner on manufactured stone before full application to confirm results and check for accent color sensitivity.

New Brick and Tile Surfaces

1. Clean construction soiling and mortar residues on new brick and tile surfaces within 14–28 days of installation for most effective results.
2. Mortar and grout smears left on the surface beyond this window become more difficult to remove and may cause undesirable results — plan cleaning schedules accordingly.
3. Allow mortar and grout to cure for at least 7 days before cleaning.
4. Test product on a small inconspicuous area before full-scale application.

General Cleaning Process

1. Dilute concentrate to the appropriate ratio on-site according to the product data sheet recommendations for the specific substrate and stain type.
2. Pre-wet the surface with clean water before applying the diluted cleaner.
3. Apply the diluted cleaner to the pre-wetted surface using appropriate application equipment.
4. Allow the cleaner to dwell for the time specified in the product data sheet, keeping the surface wet during dwell.
5. Scrub the surface as needed using appropriate brushes or cleaning equipment.
6. Rinse thoroughly with clean water to remove all cleaner residue.
7. Always read the full product data sheet and safety data sheet before application for complete instructions specific to the substrate and conditions.
