Thread: Engine bay wash down

I use a garden weed sprayer with CT18 or CT20 truck wash mixed in it. Let it soak for a few minutes then blast away with the pressure washer. I'd rather know in my driveway if my Landy can't cope with water rather than halfway across a creek. Only my S2a has some issues with running on all cylinders after a pressure wash, but that's only because it's got a Holden 202 in it. (One or two cylinders will spark across from the suppressor caps when wet). My 101 and the Deefer90 have no issues with a pressure wash.

hit mine with the karcher a few times..let it sit for a few hours in the sun to dry out, with the bonnet up, before start no problems so far,,

Maybe I need to be not so precious about my defender. CT 20 sounds like a plan.

I just cover the Pumas computer with glad wrap and try not to blast too much water on it anyway.
As others do I use a garden sprayer with truck wash and it comes up reasonable...... not that I bother too much about washing off hard won dirt and stains.
