Simple Green Oxy Solve Concrete Cleaner
Simple Green Oxy Solve Concrete and Driveway Cleaner is a peroxide-based cleaner designed to lift tough stains from concrete surfaces without relying on harsh solvents. Its oxygenating action helps break down oil, grease, rust, tire marks, and exhaust buildup, making it a strong choice for driveways and walkways. The formula is intended to be more eco-friendly than some traditional degreasers while delivering powerful stain lifting. Applications include staining removal on masonry, patios, and other flat concrete areas that see heavy use.
Simpson Cleaning 88282 Purple Cleaner
This concentrate is designed for high-performance cleaning in industrial or heavy-duty settings. It is a non-butyl degreaser formulated to cut through tough oil and grease and can be used in a pressure washer, spray bottles, or manual applications. Dilution flexibility allows you to generate up to 256 gallons of cleaning solution per bottle, delivering cost efficiency for larger cleaning jobs. It is marketed for use on concrete as well as other surfaces like vinyl siding, appliances, and fences, making it a versatile choice for mixed cleanup tasks around a property or facility.
Zep Driveway and Concrete Cleaner Concentrate
Zep’s Driveway and Concrete Cleaner is a concentrated formula aimed at removing tough oil stains and grime from concrete, brick, asphalt, and other hard surfaces. It’s marketed as a construction-grade cleaner, suitable for heavy-duty use on walkways, driveways, and parking areas. The product emphasizes stain removal performance on exterior concrete surfaces while noting surfaces that are not suitable for treatment, such as wood or painted/stained finishes that require refinishing. For frequent outdoor cleaning or for properties with persistent staining, Zep offers a potent option with strong degreasing power.
Simpson Cleaning 88283 Green Cleaner
The Green variant of Simpson’s concentrated cleaner is designed for multi-purpose degreasing across concrete and other exterior surfaces. It is marketed as non-toxic, biodegradable, and compliant with health and safety standards. Like the Purple variant, it is intended for use with pressure washers, automatic scrubbers, steam cleaners, and manual applications, offering a flexible cleaning solution for comprehensive exterior maintenance of concrete, siding, and other surfaces susceptible to oil buildup, grease, and dirt.
WOJET Surface Cleaner (Chemical Adjunct)
WOJET’s 20-inch surface cleaner is a robust accessory designed to work with high-pressure washers, helping to reduce striping and improve coverage on large, flat surfaces such as driveways and sidewalks. While primarily an attachment, it enhances the effectiveness of chemical cleaners by providing even cleaning action. The model emphasizes four-wheel stability, a sealed swivel, and a stainless steel build, contributing to durability and consistent results across expansive concrete areas.
MEKOH 14” Electric Surface Cleaner
MEKOH’s 14-inch surface cleaner attachment is designed for electric and gas pressure washers, with a maximum of 2500 PSI and a flow rate of 2.7 GPM. It features dual rotary nozzles for wide, even cleaning and faster coverage on large surfaces. The product emphasizes lightweight, durable ABS construction and a 1/4-inch quick-connect that enables quick setup to start cleaning. This tool helps maximize the effectiveness of chemical cleaners by delivering a uniform cleaning path on concrete, driveways, sidewalks, and decks.
Buying Guide: Key Purchase Considerations
- Surface compatibility: Concrete is highly porous; choose cleaners specifically formulated for concrete to avoid etching or residue buildup. Signals of suitability include phrases like “for concrete,” “driveways,” or “patios.”
- Degreasing power: For oil and grease stains, look for degreasers with strong solvent or surfactant action. Non-butyl formulas are common for safer handling, but still effective on heavy grime when properly diluted.
- Eco and safety profile: Consider cleaners that meet health and safety standards and are biodegradable or low-toxicity where possible, especially for residential use.
- Concentration and dilution: Concentrated formulas save money and enable tailored dilution for light or heavy soils. Check the bottle’s dilution ratio to estimate yield per gallon of water.
- Compatibility with equipment: Some cleaners pair best with surface cleaners or require specific nozzle settings. Review manufacturer guidance on compatible spray wands, pressure ranges, and dilution instructions.
- Color variants and branding: Different color variants may indicate formulation tweaks; verify that the product’s stated use aligns with concrete cleaning needs rather than siding or industrial equipment exclusively.
- Environmental impact and rinsing: Ensure that the product’s runoff can be managed on your property and that it won’t adversely affect nearby plants or waterways.
Comparative Considerations
- Peroxide-based cleaners (like Simple Green Oxy Solve) are often strong on organic stains but may require longer dwell times or scrubbing for deep-set grime.
- Non-butyl degreasers (as used by Simpson and Simpson Green variants) provide robust oil grease removal without harsh solvents but may require thorough rinsing.
- Concentrates from brands such as Zep offer heavy-duty cleaning for neglected surfaces but require careful dilution to avoid surface damage or residue.
- Surface cleaner attachments (like WOJET and MEKOH) improve cleaning efficiency and uniformity, especially on large concrete areas, when used with compatible high-PSI equipment and the proper chemical pre-treatment.
- Always follow label directions and test a small inconspicuous area before broad application to assess finish and colorfastness.
In summary, the best concrete cleaning solution for your pressure washing needs depends on the nature of stains, surface condition, and your preferred workflow. Combining a high-quality chemical cleaner with an efficient surface cleaner attachment often yields the most consistent, streak-free results on large concrete areas.
