Simple Green Oxy Solve Exterior Cleaner

Simple Green Oxy Solve is a peroxide-based concentrate designed to lift grime from a variety of exterior surfaces, including brick. It leverages an oxidizing action to remove stains without relying on harsh chemicals, helping keep plants and landscaping safer during application. The formula is suitable for vinyl, aluminum, stucco, wood, and brick, making it a versatile choice for homes with mixed materials.
- Surface compatibility includes brick, vinyl, wood, stucco, aluminum, and more
- Targets stains from algae, moss, and mildew with an oxidizing lift
- Formulated to lift grime while reducing harsh chemical exposure
When using, apply the cleaner to the surface, allow a dwell time for staining to loosen, then rinse thoroughly with water. For best results on brick, use a soft-bristle brush to work the cleaner into crevices, followed by a complete rinse to minimize residue and ensure an even finish.
30 Seconds Outdoor Cleaner

30 Seconds Outdoor Cleaner is designed to dissolve organic stains caused by algae, mold, mildew, and moss. The spray-and-rinse formula is convenient for exterior surfaces and is safe for lawns and plants when used as directed. The product is positioned as a fast, low-effort option that eliminates staining without requiring pressure washing, which can be gentler on brick when used correctly.
- Effective against algae, mold, mildew, and moss
- Can be used on vinyl siding, decks, patios, and brick surfaces
- Hose-end sprayer simplifies application; no pressure washer required
For brick, spray the solution onto the affected areas, allow it to dwell briefly, and rinse with a garden hose. Avoid excessive soaking of nearby plant life and rinse carefully to prevent run-off staining adjacent areas.
MasonryDefender Brick Sealer Satin Sheen

MasonryDefender Brick Sealer provides both exterior and interior protection for brick walls. This water-based acrylic sealer creates a washable, easy-to-clean surface while preserving the natural look of brick. Applied as a clear coat, it adds a satin sheen that subtly enhances the masonry while offering moisture resistance and reduced dust shedding on brick walls.
- Water-repellent protection for interior and exterior brick
- Clear acrylic formula with a satin sheen
- Helps prevent dirt buildup and simplifies future cleaning
Apply in multiple thin coats as recommended by the manufacturer to achieve uniform coverage. This sealer is best used after cleaning to lock in the cleaner’s results and extend the life of brick surfaces against moisture-related damage and dust buildup.
Quick N Brite Fireplace Gel Cleaner

Quick N Brite Fireplace Gel Cleaner is designed for brick, stone, rock, tile, and marble surfaces in fireplaces. The kit includes a heavy-duty, non-abrasive gel cleaner and a scrub brush for thorough cleaning. Its concentrated formula targets soot, creosote, and ash, offering a straightforward way to revitalize a fireplace without harsh scrubbing or abrasive tools.
- Specialized for fireplace brick and surrounding surfaces
- Non-abrasive gel that lifts soot and creosote
- Includes a scrub brush for easier application
To use, apply the gel with the included brush, let it work on grime, rinse with water, and wipe clean. The product is marketed as user-friendly and gentle enough for frequent maintenance without requiring heavy PPE equipment.
Eco Etch Pro Concrete Cleaner & Etcher

Eco Etch Pro is an etcher designed to prep concrete, brick, and masonry surfaces by removing efflorescence, rust, calcium deposits, and mortar residue. It relies on a safe organic acid chemistry as a substitute for harsher acids, creating a better surface profile for coating adhesion or subsequent cleaning. This product is positioned as a gentle alternative to traditional muriatic acid-based etchers.
- Etches concrete and masonry to improve surface porosity
- Removes efflorescence and mortar deposits
- Non-toxic organic acid alternative to traditional acids
Use with proper ventilation and follow label directions for dilution and contact time. It is typically employed prior to coating, sealing, or deep cleaning to ensure bricks and other masonry surfaces present an ideal substrate for maintenance work.
Buying Guide
Key purchase considerations
- Surface compatibility: Choose products designed for brick, masonry, or concrete to avoid dulling or damage to the surface texture.
- Stain type and severity: Algae, moss, mildew, soot, efflorescence, and mortar deposits each respond differently to cleaners, gels, and etchers. Match the product to the dominant stain present.
- Concentration and coverage: Concentrates offer cost savings but require dilution and more handling. Review coverage estimates and expected dilution ratios to estimate total material needs for your project.
- Application method: Sprays, foams, gels, and wipes each have use cases. Consider whether you prefer hose-end sprays for large areas or brushes for crevices and mortar joints.
- Rinse and residue: Some formulas require rinsing; others are designed to be rinsed with water flow. Plan for adequate rinsing to prevent streaks or residue buildup on brickwork.
- Safety and environmental impact: Look for biodegradable, non-toxic formulations when possible. Wear protective gloves and eye protection, especially with acids or strong oxidizers.
- Finish and protection: If you intend to seal brick after cleaning, pair a cleaner with a compatible sealer to improve longevity and resist future staining.
- Ease of use and time: Products that require less effort (no-pressure-washing options, quick dwell times) can reduce overall project time, especially on larger homes.
- Cost per project: Compare price per gallon, plus dilution ratios, to gauge overall cost. Some concentrates offer significant value for larger cleaning tasks.
Surface-focused considerations
Brick and masonry surfaces vary in porosity and texture. Porous brick can absorb more cleaner and require longer dwell times, whereas smooth brick may rinse more easily. For historical masonry, test a small inconspicuous area first to confirm no color change or surface dulling occurs after cleaning or sealing. For outdoor brick exposed to weather, consider a follow-up with a protective sealer to reduce future staining and moisture infiltration.
Comparative notes
- Oxidizing cleaners (like peroxide-based formulas) tend to lift organic stains effectively with less risk to sensitive plants when used as directed.
- Foam and gel products can provide targeted contact on vertical brick surfaces and reduce overspray concerns near landscaping.
- Sealants add ongoing protection but require a clean, dry surface for best adhesion and even coverage.
- Etchers are best for efflorescence and mortar deposits but should be used with caution on decorative bricks or aged masonry finishes.
