EaCo Chem NMD 80 Masonry Detergent
This product targets mortar smears and efflorescence on diverse masonry surfaces. It is described as safe, effective, and easy to use with no scrubbing required, improving productivity for outdoor projects. It is marketed as a biodegradable solution and does not require a respirator when used outdoors. Best for contractors or homeowners cleaning brick, concrete, stone, and related materials where efflorescence is a primary concern.
Who it’s best for: Small to medium exterior brick cleaning jobs, DIY homeowners, and professionals who want minimal effort with solid results on multiple masonry substrates. Limitations: outdoor use is emphasized; verify indoor ventilation needs if used indoors.
EaCo Chem Heritage Restorer (1 Gallon)
The Heritage Restorer line emphasizes non-corrosive technology aimed at historic or sensitive substrates. The formula combines surfactants, mild acids, and water-based solvents to remove mineral oxide residues and hydrocarbon-based stains. It’s pitched as versatile for brick, limestone, sandstone, granite, terracotta, terrazzo, and more. Best for historical restoration or projects where preservation of substrate integrity matters.
Who it’s best for: Projects involving historic masonry or delicate surfaces where aggressive cleaners could cause damage. Limitations: the product is described as non-corrosive but practitioners should test on a small area first to ensure substrate compatibility.
EaCo Chem Heritage Restorer (5 Gallon)
This larger-volume Heritage Restorer option targets the same non-corrosive restoration niche as the 1-gallon version but is positioned for bigger jobs and ongoing maintenance projects. It uses a similar blend of surfactants and mild acids to lift mineral and oxide residues from brick and stone surfaces. Best for restoration crews or facility managers cleaning multiple walls or large historic sites.
Who it’s best for: Professional restoration teams or owners planning repeated cleanings across extensive masonry surfaces. Limitations: verify container handling and storage guidelines for multi-gallon purchases.
Zep Part Wash Cleaning Detergent Powder
Zep Part Wash is a high-performance detergent designed for metal surfaces and industrial cleaning environments. It is suitable for hot vat or recirculating spray wash cabinets and is safe for all metals, including aluminum and zinc. This option is best for heavy grime, industrial brick applications, or masonry shops where robust cleaning power is needed. It’s a strong choice when traditional masonry detergents lack the required aggressiveness.
Who it’s best for: Industrial settings and large-scale brick or concrete cleaning where rugged performance is essential. Limitations: may be too strong for delicate historic brick without proper dilution and surface testing.
Sun Joe Snow Foam Car Wash Soap & Cleaner Concentrate
This concentrate focuses on creating a thick foam that lifts dirt and contaminants. It uses biodegradable ingredients and claims gentleness on paint, wax, and sealants. While marketed for automotive cleaning, the foam action and safety profile make it a practical, light-cleaning option for brick surfaces in exterior settings or for vehicles with brick-adjacent finishes. Best for light, frequent cleaning where soap lather helps access textured brick surfaces.
Who it’s best for: Homeowners or small businesses performing regular exterior brick cleaning with light to moderate soil. Limitations: not a heavy-duty solution for deep mineral deposits or tough efflorescence compared to dedicated masonry detergents.

- Outdoor suitability: If used outdoors, ensure the product allows outdoor use without respirator requirements and is biodegradable when possible.
