For tough cleaning tasks, like removing stains from concrete, or monster ones, like washing an entire house, elbow grease goes only so far, say the experts at This Old House magazine.
Features to look for include:
1. A handle, with slots for the tips, hose, and wand, that collapses for storage.
2. A steel-reinforced rubber hose will outlast PVC versions.
3. A beefy, tubular steel cage protects the engine.
4. An easily accessible pump facilitates service.
5. Puncture-proof wheels.
Don’t be dazzled by psi, or you may end up with plenty of pressure but not enough flow. Instead, calculate cleaning units (CU) by multiplying psi by gpm. This factor better represents the cleaning power you really have. The higher the CU, the deeper you can clean and the faster it’ll go.
Before dusting it off for another round of outdoor spring cleaning, Make sure your pressure washer is up to snuff with these steps:
1. Replace the air filter to keep dirt and debris from getting into the engine.
2. Change the oil so that it’s fresh for the season.
3. Clean the water inlet screen with dish soap and a small brush to make sure it’s not clogged.
Pro TIP: “Run an $8 can of Pump Saver through your pressure washer before storing it for the winter to protect the pump and keep the seals from drying out.” —Bill Mikenis, Pressure Washers Direct
