Looking to buy a power washer for general residential projects, and to wash my car. Should I go gas or electric? What PSI range is safe and effective for our cars? What modesl are you recommending? Many thanks to all.

Yikes!  You should NOT be using a power washer on any car as they can generate enough power to blow the paint right off the car, as well as destroying any rubber seal it touches.  BAD IDEA!

I'm going to respectfully disagree with JFP.  Numerous detailing professionals and us normal people use a pressure washer to wash cars. I suggest further reading at Detailers Domain, Ammo NYC, Adams Polishes for more information.

 

I use an electric pressure washer for my gar. Gas versions may produce to much PSI and flow rate that can be an issue in car washing.

Used with appropriate care, it is possible, but considering the damage list from pressure washing that has come into the shop over the years (dented panels, lifted paint, blown out seals, flattened tires, damaged brakes, holed cabriolet tops, emblems blown off, ripped bumper covers, etc. etc.), I would still caution against its use.  The problem with these devices always lies with the operator, who seem to believe that is one PSIG is good, and two is even better, then forth seven has got to be just right; and that is when all Hell breaks loose...……………....
