Sounds like hydrophobic glass. I find it easier to use a brush with fan jets on them instead of pencil jets. Rinse rinse and rinse some more. When you're rinsing and have came across the glass in one direction only move the brush down an inch or so before you go across the other direction. I've seen on forums about people using additives to the pure to help the water sheet better but plenty of rinsing does the trick.

Thanks for the advice
The comment before is correct it's hydrophobic glass (beads)
Hydrophilic glass (sheets)
Personally I use pencil jets on all glass fans are messy especially in the winds.
Not sure what you flow rate is but maybe turn it up a little this will aid in rinsing.
I've trained 100's of window cleaners with the use of water fed poles over 95% use pencil jets
Side note: your 450gpd sounds like there is a blockage or the waste is to high. I use 4040's due to speed of filling but I employ people, if you don't use the amount of water you can make in 12 hours you don't need a bigger ro, reseat all the membranes and makes sure there is no air in the system because it sounds like there is or the clave open to much

Thanks for the advice Ian really appreciate it. My flow was on number 1 so will turn it up.as for the RO i have ordered a booster pump from windows cleaning warehouse. My pressure is quite low 2.4 bars think need at least 60 psi to optimise the system.
