Obviously I have no idea if your forks are full of water but…
Earlier this year I had a set of revs and some fox 36 talas forks serviced. Both had lots of water (maybe 1/2 pint in the fox's although I can't quite remember)in the lowers, making both forks feel very stiff and generally horrible. I never (well almost never) wash my bikes with a jet wash and generally use a dirtworker. But the advice I was given was to always wash a bike upside down. Having said that the revs had done a couple of hard winters and fox's are known for having lose seals so perhaps it's just always wash bikes with fox forks upside down.
I wouldn't have thought (based on my very limited experience) that water would do anything worse than add a little unwanted compression damping. Go out for a ride and get them serviced when you get back.
