Simple Green Oxy Solve Total Outdoor Pressure Washer Cleaner
The Simple Green Oxy Solve Total Outdoor Cleaner combines peroxide-powered cleaning with a formulation designed for outdoor surfaces. It is capable of lifting dirt, grime and stains from mold, mildew, moss and algae, on a wide range of materials including wood, composite, vinyl, metal, fabric, plastic, wicker, concrete, stone, brick and asphalt.

Use with appropriate outdoor equipment and follow label directions for best results.
Key features include a peroxide-enhanced action that targets organic stains and an emphasis on surfaces commonly found around homes and commercial properties. This makes it suitable for multifaceted cleaning tasks, from decks to walkways. As with all cleaners, test on inconspicuous areas first and observe surface compatibility before broad application.
Oxy Solve House And Siding Pressure Washer Cleaner
This concentrate is designed to remove stains from mold and mildew on exterior surfaces such as vinyl, aluminum, wood, brick and stucco. It uses peroxide power to lift grime without resorting to harsh chemicals, addressing common exterior cleaning needs for homes and light commercial properties. The product is suitable for use on house exteriors and siding projects where a less aggressive yet effective approach is desired.
Typical applications include vinyl siding, aluminum panels, wood siding and brick facades. Always follow dilution guidance and rinse thoroughly to avoid residue. For large areas, consider batching projects to maintain consistent results and to prevent streaking on lighter colors.
Simple Green Industrial Cleaner And Degreaser
This industrial-strength cleaner is designed to remove heavy dirt, grease, food residue and stains from washable surfaces. It is recognized by the U.S. EPA’s Safer Choice Program and is suitable for cleaning counters, carpet, floors, machines, equipment and vehicles. The formulation emphasizes heavy-duty cleaning without compromising safety, making it a go-to option for facility maintenance teams and professional cleaners working with diverse substrates.
When using an industrial cleaner, apply according to label directions, test on sensitive materials, and ensure appropriate PPE is used for degreasing tasks. The product’s versatility supports a wide range of cleaning scenarios, from workshop floors to outdoor equipment surfaces that require stronger degreasing power than typical household cleaners.
ZEP House/Siding Wash
ZEP’s House/Siding Wash is capable of cleaning large exterior areas, with coverage up to about 5,000 square feet for typical applications. The concentrate formulation makes up to 20 gallons when diluted appropriately. This product targets common exterior contaminants such as mildew, algae and general grime on siding and related surfaces, providing a cost-effective option for medium-to-large residential or commercial cleaning tasks.
For optimal results, measure dilution carefully to avoid surface damage and ensure thorough rinsing. Suitable for siding, decks and exterior masonry, the product can be used with pressure washers or manual scrubbing as needed. Always wear protective gear and follow the label’s safety recommendations during handling and application.
ZEP All-In-One Pressure Wash
The ZEP All-In-One Pressure Wash is designed to tackle dirt, grease, oil, grime, road film and stains caused by mold or mildew. It is described as suitable for use with pressure washing equipment or manual application, offering flexibility across different cleaning setups. The all-in-one formulation can simplify workflows by combining cleaning power with surface-safe performance for an array of materials often encountered in exterior cleaning projects.
When using all-in-one products, follow dilution and application guidelines to balance cleaning efficacy with surface safety. This option is particularly appealing for operators who need a straightforward solution that performs across multiple substrates without switching products mid-task.
Buying Guide: Key Purchase Considerations
Surface compatibility is paramount. Always verify whether a cleaner is suitable for wood, vinyl, brick, metal or concrete, and test on a small area first to avoid discoloration or damage. Dilution control matters; many formulations work best when diluted to specific ratios to balance cleaning power with safety. For large exterior jobs, consider concentrates that cover more square footage per gallon and provide cost efficiency.
Environmental and safety factors are essential. Look for products recognized by EPA Safer Choice programs when possible, and review labels for required PPE and ventilation guidelines. Peroxide-based or green-clean formulations may offer strong performance with reduced harsh chemical exposure, which is beneficial for both workers and outdoor vegetation near cleaning zones.
Application method and equipment compatibility influence outcomes. Some cleaners are designed for pressure washers, while others are suitable for hand scrubbing. Consider whether you need rapid surface cleaning, mold and mildew staining control, or heavy grease removal, and choose a formula that aligns with the project’s scale and surface type.
Cost and coverage should factor into planning. Concentrates that yield more gallons per container typically provide greater value for large properties. Compare dilution requirements, cleaning strength, and required rinsing to estimate total labor and water usage. For ongoing maintenance, selecting a versatile product that works across multiple surfaces can simplify procurement and inventory management.
Safety and storage are practical considerations. Store cleaners away from direct sunlight and in original containers with clear labeling. Follow disposal guidelines for concentrate and rinse water, particularly in outdoor environments where runoff could impact landscaping or drainage.
Versatility versus specialization is a trade-off to weigh. All-in-one cleaners offer convenience for mixed surfaces, while surface-specific formulas may maximize effectiveness on a single substrate. Assess your typical cleaning tasks to determine whether a general-purpose or a specialized option best fits your operation.
