Simple Green Oxy Solve Total Outdoor Pressure Washer Cleaner
This 1-gallon formula from Simple Green uses peroxide power to tackle dirt, mold, mildew, moss, and algae across a wide range of outdoor surfaces. It lifts grime from wood, vinyl, metal, fabric, concrete, stone, brick, and asphalt without harsh solvents. The peroxide-based approach helps break down stains while remaining more environmentally friendly than some solvent cleaners. Ideal for patios, fences, and exterior surfaces that accumulate organic growth.

It removes stains from algae, moss, and mildew while using peroxide to lift grime without harsh chemicals. This cleaner is well-suited for durable siding cleanup tasks and is designed to be gentle on most exterior materials while delivering strong stain removal.
Simple Green Oxy Solve Concrete & Driveway
This purple, unscented cleaner targets concrete and driveways, lifting tough oil stains, rust, grease, automotive fluids, tire marks, and exhaust buildup. As with other Oxy Solve products, it relies on peroxide to lift grime without harsh chemical residues, making it a solid option for masonry and hardscape maintenance.

It is designed to deliver uniform cleaning on flat surfaces such as decks, driveways, patios, walls, and more.

Simpson Cleaning 88281 Concentrated Cleaner
Similar to the 88282 version, this blue-labeled Simpson cleaner provides a multi-purpose, non-butyl degreaser option. It is designed for use with pressure washers and spray bottles and is highly concentrated, allowing for dilution to maximize gallons covered. It supports cleaning concrete, vinyl siding, appliances, windows, cars, fences, decks, and more while reducing the need for multiple cleaners.
MEKOH Pressure Washer Surface Cleaner 20″
MEKOH’s 20″ surface cleaner is built for higher power and water flow, featuring two high-pressure jets and a 3/8″ quick-connect. The design emphasizes non-marking cleaning with a stainless steel chassis and replaceable nozzles for flexible cleaning patterns. It covers large areas quickly and is compatible with cold, hot, and optionally soapy water conditions, making it suitable for patios, driveways, and other expansive surfaces.
Buying Guide
When choosing cleaners and attachments for pressure washers, consider these factors to tailor selection to your needs:
- Surface compatibility: Look for formulas labeled safe for concrete, vinyl, wood, brick, and metal. Peroxide-based cleaners lift grime while reducing harsh chemical exposure on sensitive surfaces.
- Application type: Decide between concentrate cleaners for bulk coverage and ready-to-use options for spot cleaning or quick jobs.
- Attachment compatibility: Surface cleaners require a compatible PSI and a 1/4″ quick-connect or standard fittings. Ensure your pressure washer can handle the cleaning unit’s PSI rating.
- Environmental and odor considerations: If you’re cleaning outdoor spaces near landscaping or pets, choose unscented or milder formulations when possible.
- Time and effort: Large-area tasks benefit from wide-spray attachments with dual-jet designs to speed up cleaning and reduce fatigue.
- Maintenance and disposal: Check whether the cleaner is biodegradable and easy to rinse off, minimizing runoff and residue on treated surfaces.
For surface-heavy tasks, combining a strong concentrate with a wide-area surface cleaner can deliver efficient results. For maintenance, choose multi-surface cleaners that work across concrete, siding, and driveways to simplify your cleaning routine.
