Can anyone see a problem with squirting water up into the soffit vents to clean them? I am thinking that most of the water would drain straight back out. What about the pressure washing guys do you do this?

The thing you have to watch with useing a pressure washer for this type of work, is actually blowing the soffits out of there seating, most modern soffits are just sat into place, blast the pressure washer directly upwards and it may disloge it, resulting in ladders out to reseat the soffit,
if you angle the jets at more of an angle to the soffit you can get away with it, some soffits are fixed down into place, if this is the case then blast away, but direct as little as possible at the vents.
