Cleaning — FAQ
What PSI do I need to clean my garage floor?
For standard concrete garage floors, 2000-2500 PSI effectively removes oil stains and grime without damaging the surface. Heavily stained floors may benefit from 3000+ PSI, but always test in an inconspicuous area first.
Can I use a pressure washer on epoxy garage floors?
Yes, but keep pressure below 2000 PSI and use a 25° or 40° nozzle. Epoxy coatings can peel under high pressure. Pre-treat stains with a garage floor detergent and let it dwell before gentle rinsing.
Are electric pressure washers powerful enough for garages?
Modern electric models reaching 2000+ PSI handle garage cleaning tasks effectively. They're safer for indoor use, quieter, and require less maintenance than gas units. For professional daily use, consider higher-end gas models.
How important is GPM for garage cleaning?
GPM determines cleaning speed. A 2.0-2.5 GPM unit rinses detergent and debris faster than 1.5 GPM models, reducing overall cleaning time by 30-40% for large garages. Prioritize GPM if you clean frequently.
Do I need a foam cannon for my garage pressure washer?
Foam cannons significantly improve cleaning efficiency by pre-treating surfaces with thick detergent foam. They're essential for vehicle detailing and help break down garage floor oil stains. Most quality units include or offer compatible foam cannons.
Can I store a pressure washer in my garage during winter?
Drain all water from the pump, hoses, and wand to prevent freeze damage. Store in a heated area or add pump antifreeze. Electric units tolerate cold better than gas models, but water expansion will crack components.
