daverclasper Posted June 2, 2021 Report Share Posted June 2, 2021 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 Link to comment Share on other sites More sharing options...
poppyman Posted June 2, 2021 Report Share Posted June 2, 2021 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. Tony. Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 2, 2021 Report Share Posted June 2, 2021 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 Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted June 3, 2021 Report Share Posted June 3, 2021 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. Link to comment Share on other sites More sharing options...
Chris A Posted June 3, 2021 Report Share Posted June 3, 2021 Steam clean? 😲 I have heard of companies that clean engine bays using (I think) low temperature CO2? Link to comment Share on other sites More sharing options...
Clive Posted June 3, 2021 Report Share Posted June 3, 2021 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. Link to comment Share on other sites More sharing options...

Save the pressure washer for cleaning oil off the driveway! Nigel Link to comment Share on other sites More sharing options...
daverclasper Posted June 3, 2021 Author Report Share Posted June 3, 2021 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. Cheers, Dave Link to comment Share on other sites More sharing options...
