Is it safe to use pressure washer?

 

Kind of like asking if it's safe to use a rotary buffer...

Same answer; Yes, IF you understand the dangers and know what NOT to do, and the way to use it properly. If you use it in close proximity at too high a psi. then you can tear off taped emblems, moldings. trim etc. On repainted cars, I've known people that have stripped off (poorly prepped) paint with one.

Common sense never was more necessary than when using a pressure washer. Personally, I've never used one to wash a car because in my experience, they never get a car as clean as with mechanical (i.e.=HAND) agitation via a wash mitt and car wash soap.

That's just me though.

If you're careful and know how to use one, then you'll be ok. Happy Holidays.

 

I wouldn't use it on the painted surface as I would expect it could scratch the paint. I do occasionally use it for the under body, wheel wells and tires.

 

Could you please tell me how to use one? Would it be safe to use say pressure washer that delivers 1,700 psi at 1.5 gpm, or 2,290 psi with the turbo nozzle?

 

Hoy Smoke! you know with pressures like that you can cut through concrete. Does that sound safe to use on your car? The idea is to remove the dirt in the gentlest fashion possible. Once you get the car clean and properly prepped (clay bar, polished) and protected (sealant &/or waxed) then regular washing in the future will be fairly easy as the slick surface will shed dirt with very little effort. Read some of the expert accounts on washing/detailing cars. They advise using free flow hose with NO nozzle to rinse the car. That's the furthest thing from 2000+ psi.
