Cleaning — FAQ
What size pressure washer do I need for home use?
3,000-3,400 PSI with 2.3-2.6 GPM handles driveways, decks, and vehicles. This delivers 7,000-9,000 cleaning units—enough power without surface damage. Avoid 4,000+ PSI for residential siding or wood.
How long do gas pressure washers last?
Residential models last 5-7 years with proper maintenance. Commercial units run 10+ years. Key factors: pump quality, engine brand, and storage practices. Always use fuel stabilizer and pump antifreeze.
Are electric pressure washers better than gas?
Electric models are quieter and need less maintenance but max out at 2,000 PSI. Gas units deliver 3,000-4,400 PSI for heavy concrete and paint prep. Choose gas for speed and power; electric for light car washing.
Why does my pressure washer lose pressure?
Check the nozzle first—clogs reduce pressure by 50%. Inspect inlet screen for debris. Worn pump seals cause gradual pressure loss. Thermal relief valve activation from overheating creates sudden drops. Replace seals yearly.
Can I use bleach in my pressure washer?
Only if the manual specifically approves it. Bleach corrodes aluminum pumps and voids warranties. Use manufacturer-approved detergents. Downstream injectors after the pump are safer than upstream systems.
How do I winterize a gas pressure washer?
Run pump antifreeze through the system until it exits the gun. Drain all water from hoses and gun. Add fuel stabilizer to the tank and run the engine for 2 minutes. Store indoors or cover tightly.
