I just got done cleaning the underside of my RV hood. It was dirty and I didnt like the way it looked so I washed it and waxed it... Cleaned everything else under there too..
You know, my old ex father-in-law once tried to turn a garden hose on one of my engines. I sent him packing. LOL do you guys really take a garden hose to your engine compartment?
I can’t even imagine what that would do to your electrical connections.
