Is 3000 PSI enough to clean concrete?

Yes — 3,000 PSI is more than enough for virtually any residential concrete surface, including driveways, garage floors, and patios with years of embedded oil stains, algae, or tire marks. In fact, most concrete cleaning happens comfortably in the 2,000–3,000 PSI range, with 2,500 PSI often cited as the ideal balance of cleaning power and safety for standard slabs. At 3,000 PSI, use a 15° or 25° nozzle rather than a pinpoint 0° tip, and keep the wand moving steadily rather than hovering in one spot, which can pit or streak the surface. Healthy, undamaged concrete handles this pressure well; older or already-cracked concrete should be tested in an inconspicuous area first before doing the full surface.
