Simple Green Oxy Solve Concrete Cleaner
Simple Green Oxy Solve is a peroxide-powered cleaner formulated for concrete and related masonry surfaces. It targets tough stains such as oil spills, rust, grease, automotive fluids, tire marks, and exhaust buildup without relying on harsh chemicals. The product is unscented, which can reduce overpowering odors during application, and it is designed for use with standard pressure-washing equipment on driveways, walkways, patios, and other masonry areas.
The peroxide-based action helps lift grime from surface pores, contributing to a cleaner appearance after a thorough rinse. The formulation is suitable for concrete cleaning tasks that involve embedded staining and broad surface areas. For best results, apply evenly, allow a brief dwell, agitate if needed, and rinse with a pressure washer. It works as a versatile option for a single-step approach to routine exterior cleaning.
SIMPSON Heavy Duty Cleaner
SIMPSON 88282 Cleaner is a concentrated soap solution designed for pressure washers and spray bottles. It is presented as a heavy-duty cleaner capable of tackling tough oil and grease on concrete, vinyl siding, appliances, windows, cars, fences, and decks. The product is described as a non-butyl degreaser that can cut through stubborn residues, reducing the need to combine multiple cleaners for a job.
The cleaner is marketed as highly versatile, usable in equipment such as pressure washers, automatic scrubbers, and steam cleaners, as well as for manual spraying, mopping, or wiping. Its high concentration allows dilution to achieve substantial cleaning yields—up to 256 gallons of cleaning solution per bottle—making it a cost-effective option for large cleaning projects where multiple surfaces are involved.
Zep Driveway And Concrete Cleaner
Zep Driveway and Concrete Pressure Wash Cleaner Concentrate is a construction-grade cleaner designed to remove tough oil stains, dirt, and grime from concrete, brick, asphalt, and aggregate surfaces. It is positioned as highly effective for walkways, patios, driveways, and parking lots, delivering strong cleaning power for outdoor hardscapes.
The product is not intended for wood, painted, sealed, or stained surfaces that have not been refinished, indicating it should be used selectively on materials that can tolerate stronger cleaners. The concentrate format allows scaling to larger jobs, making it suitable for homeowners and professionals tackling extensive exterior cleaning tasks where heavy soiling is present.
BEEST Vinyl Siding Cleaner
BEEST Vinyl Siding Cleaner for House Wash is a highly concentrated formula designed to produce up to 26 gallons of pressure-washer soap. While marketed for vinyl siding and exterior surfaces, it is described as a multi-surface cleaner suitable for vinyl, concrete, stone, plastics, outdoor furniture, fabrics, walls, floors, and more. This broad compatibility makes it a versatile option for exterior cleaning tasks involving multiple materials.
The product emphasizes whitening and brightening outdoor surfaces and removing dirt, grime, and airborne algae to restore a refreshed appearance. Its concentration level suggests a lower per-use cost for large exterior cleaning projects, particularly when multiple surfaces require treatment in a single job cycle.
EDOU 18-Inch Surface Cleaner
EDOU 18-Inch Pressure Washer Surface Cleaner is a stainless steel attachment designed for efficient cleaning of large, flat surfaces like patios, driveways, sidewalks, and decks. It supports a maximum of 4,000 PSI and includes dual nozzles and extension wands, offering broader coverage and reduced cleaning time compared to standard spray wands. The all-metal construction emphasizes durability and long service life under frequent outdoor use.
The unit features four casters to improve maneuverability and stability, minimizing splatter and protecting adjacent surfaces during operation. A built-in screen filter and quick-connect fittings aid maintenance and setup, making it a practical choice for homeowners who regularly tackle large concrete areas and want even, consistent results across wide areas.
Buying Guide
Key considerations for choosing concrete cleaners
- Surface compatibility: Concrete and masonry surfaces generally tolerate peroxide-based cleaners and heavy-duty degreasers, but painted, sealed, or stained wood and some specialized coatings may be adversely affected. Check compatibility with your specific surface before use.
- Stain type and cleaning goals: Oil and grease stains often respond well to degreasing formulas (such as SIMPSON) and heavy-duty cleaners (like Zep). For general grime and algae along with routine deep cleaning, peroxide-based cleaners (such as Simple Green) can be effective.
- Concentration and dilution: Concentrated cleaners offer greater coverage per bottle, but dilution requirements vary. High-concentration products may require specific dilution ratios to balance efficacy and safety for surface materials.
- Application method and equipment: If you rely on a pressure washer, ensure the product is labeled for use with pressure washers and that your machine’s PSI rating is compatible with the cleaner’s recommended range. Some products are compatible with manual spray or mop applications as well.
- Multi-surface versus specialty: Multi-surface cleaners provide flexibility for different exterior materials, while specialty products may target specific stains (oil, rust, algae). Consider whether you need one product for several tasks or a dedicated cleaner for a particular issue.
- Environmental and safety considerations: Look for biodegradable formulas, low-odor options, and clear safety instructions. Use PPE as recommended, and store chemicals away from children and pets.
- Packaging and yield: Larger bottles or concentrates can reduce cost per use, especially for big jobs like driveways and multiple surfaces. Be mindful of disposal guidelines for concentrate concentrates after use.
