Power Washing Tips: Easy DIY Tricks for a Spotless Home Exterior

Got a dirty driveway, grimy patio, or moldy siding? A power washer can turn that mess into sparkle in minutes. The trick is knowing the right settings, safety steps, and a few handy hacks. Below are the basics you need to get great results without breaking the bank.

Pick the Right Pressure and Nozzle

Not every surface can handle the same force. For concrete driveways, aim for 2,500‑3,000 PSI with a 25°‑40° nozzle – that’s strong enough to lift oil stains but gentle enough to avoid gouges. Wooden decks need only 1,200‑1,500 PSI and a 40°‑65° nozzle to prevent splintering. If you’re cleaning delicate brick or painted walls, drop down to 800‑1,000 PSI and use a 65° fan tip. Starting low and testing a small hidden spot saves you from costly repairs.

Prep, Protect, and Apply the Right Cleaner

Before you fire up the machine, sweep away loose debris. This prevents the wand from kicking up grit that could scratch the surface. For stubborn stains, apply a biodegradable cleaning solution and let it sit 5‑10 minutes. A mix of dish soap and warm water works for most grime, while a 1:1 vinegar‑water blend tackles mildew on siding. Rinse thoroughly; leftover detergent can attract dirt later.

Safety matters. Wear goggles, gloves, and non‑slip shoes. Keep the wand at a 45° angle, pointing away from you. Never aim the jet at windows, e‑gates, or outdoor lighting – the pressure can shatter glass or bend wires.

When you finish, walk the area and spot‑check for missed spots. A quick second pass on stubborn areas is easier than trying to scrub after the surface dries. And remember to flush the washer with clean water to avoid clogging the pump.

These power washing tips work for driveways, patios, fences, and even the exterior of your home. Combine them with a regular cleaning schedule – once every spring and autumn – and you’ll keep mold, algae, and oil from building up. Your curb appeal stays high, and you’ll save money on professional services.
