Cleaning — FAQ
What PSI do I actually need for home use?
2000-2500 PSI cleans cars, grills, and wood decks safely. 2800-3200 PSI strips paint and cleans concrete effectively. Above 3500 PSI is overkill for most homeowners and risks damaging surfaces. Match nozzle angle to task: 40° for cars, 15° for concrete.
Are electric pressure washers powerful enough compared to gas?
Modern electric models reaching 3000+ PSI match gas performance for 90% of tasks. Electrics start instantly, run quieter, need no fuel mixing, and weigh half as much. Gas still wins for remote job sites without power and all-day commercial use, but electrics dominate residential budgets.
Can I use hot water in my electric pressure washer?
No—unless explicitly rated for hot water (rare in budget models). Most electric washers handle max 100°F inlet temperature. Hot water melts seals and warps plastic pumps, voiding warranties. For greasy stains, use cold water with a degreasing detergent instead.
How often should I perform maintenance?
Flush the pump with clean water after each use to prevent mineral buildup. Check inlet filter weekly; clean or replace monthly. Inspect O-rings on hose connections quarterly—cracked rings cause pressure loss. Winterize with RV antifreeze if stored below freezing.
What's the difference between soap and detergent?
Soap is natural (fat-based) and works in hot water; detergent is synthetic and performs better in cold water. Pressure washers require low-foaming detergents designed for pump systems. Household dish soap creates excessive suds that can damage seals—always use manufacturer-approved solutions.
How should I store my pressure washer in winter?
Drain all water from pump, hose, and wand to prevent freeze damage. Add pump saver antifreeze and pull starter cord (or run electric) briefly to circulate. Store indoors above 32°F if possible. Never store with pressure in the system—relieve trigger after each use.
