Cleaning — FAQ
How much PSI do I need to clean a patio?
3000-3500 PSI works for most patios. It removes dirt, mildew, and light stains without damaging concrete or mortar. For heavily stained restoration, 4000+ PSI with proper nozzles may be necessary.
Are gas pressure washers better than electric for patios?
Gas units deliver 2-3x more power and mobility—no cords limit reach. They clean faster and handle larger patios. Electric models suffice for small decks but struggle with deep concrete stains.
Can pressure washing damage paver patios?
Yes, excessive PSI displaces joint sand and can chip pavers. Use 25°-40° nozzles at 3000 PSI maximum. Keep the wand 12+ inches from surface and work in sweeping motions.
How long do gas pressure washers last?
With proper maintenance, 5-10 years. Change oil after first 5 hours, then every 50 hours. Use fuel stabilizer, winterize in cold climates, and replace pump oil annually.
What maintenance is required?
Check oil levels before each use. Flush pump after every job. Inspect hoses for cracks monthly. Replace air filter annually. Use ethanol-free gas to prevent carburetor issues.
What hose length do I need for a patio?
25 feet covers most residential patios. For patios over 500 sq ft or with obstacles, 32 feet saves significant time. Measure your space before buying—extensions reduce pressure.
