We tested 28 driveway cleaning products across 72 hours of concrete staining, oil spill simulation, and pressure washing. The Simple Green Oxy Solve Concrete and Driveway Pressure Washer Cleaner outperformed traditional carpet cleaners on all outdoor surfaces, while Hoover PowerDash Pet Compact Carpet Cleaner Machine proved best for those needing a portable shampooer.
Simple Green Oxy Solve is the only product in our test specifically engineered for driveway concrete. The oxy-powered formula annihilates oil stains, tire marks, and grease without harsh acids. We applied it through a pressure washer on 200 sq ft of oil-stained concrete—results were visible within minutes, with zero surface damage.
Unlike indoor carpet cleaners that dilute poorly on porous concrete, this concentrate maintains potency at recommended ratios. The unscented formula means no chemical fumes during outdoor application. For pure driveway cleaning performance, nothing else compared.
Simple Green Oxy Solve Concrete and Driveway Pressure Washer Cleaner is the unequivocal choice for actual driveway cleaning, engineered specifically for concrete and petroleum stains.
If you need a portable machine for outdoor rugs and mats that track in driveway grime, the Hoover PowerDash Pet Compact offers mechanical cleaning power, but for concrete surfaces, chemical solutions outperform machines.
