Try doing it with fan jets, see the difference.
I'm with Matt - fan jets appear to rinse hydrophobic glass much better than pencil jets.
However, there are different types/manufacturers of jets.
Some force the water out as an 'aerosol' spray.
Some force the water out as a 'sprinkler' spray.
I find it easier to control where the water goes with the second type.
Matt - what type have you got?
PS Matt - what about a different picture - I'm starting to think that you really look like that!
