Pressure washing

[daverclasper]

Hi.  Some benefits from doing underside of car after winter I assume.

Any negatives?, or areas of car to avoid (thinking of any bearings, spray could get into, also chassis box sections, where water may sit?, in fact maybe the whole of the underneath in that case?).

Cheers, Dave

Personally Dave i wouldn't put a pressure washer anywhere near my cars, on top or underneath. Just my take on it. Other's might have different opinions.

best avoided there is nothing in the design of the sealing to take a pressure wash without filling up things you want dry

a high pressure wash under the wheel arches is all i would   be careful about

Lower engine bay  - block and sump only, plus front suspension areas, and usually just to wash off oil or road debris to clean parts I'm going to be working on. 

A pressure washer will find leaks and loose paint that you never knew existed.

Steam clean? 😲

I have heard of companies that clean engine bays using (I think) low temperature CO2?

I have used a normal garden hose. And found the "hanging basket" hose attachments pretty handy for rinsing the underside of a car. Gets the muck out from the nooks and crannies. When dry a squirt of your favoured xax protection is not a bad idea.

Pressure washers can remove paint and protective wax. Garden hose for cleaning my cars. Save the pressure washer for cleaning oil off the driveway!

Thanks. I have been using that hose attachment. Maybe my mains pressure is on the low side, as it doesn't remove the visible salt that has dried (shows as white,against dark coloured car) on the outer body, so assume it's not effective on underside.

Maybe no answer to this one?

I try not to use in salt, though get caught out sometimes, as only car.
