I'm still convinced it's nowt to do with your wfp GB!

They were probably there all along, you just don't see them the same when looking face on from the ladder.

your probably right winpro! thanks!always good to hear your opinion mate!

If these spots are on the exterior glass it might now take something like mdr to get rid of them. Just because the windows are upvc it doesn't mean that they won't chalk and bleed like wooden or Ali windows.

The problem might be that the windows are south facing in the sun all day and that the sun has helped oxidise the frames, therefor the frames would need extra scrubbing each time to make sure that the problem doesn't reaccour.

We can tend to think that all upvc frames are ideal for wfp but many old ones on the sunny side of the house can be very problematic, the water can come off looking like milk, and after you clear the problems up you can start them all up again by getting a hot water system .

That would melt my head to get that type of a result, it looks cat. You still getting that with the new system bud? I still use the old yellow poles I got with the Ionics back in '06. I use one pole for the ground and another for the 1st floor ( no commercial here no in Eire anymore, you won't get paid).
Technique. - Wash the first floor first good scrub north south, east west yada yada yada. leave the pole standing against the cill. Then wash the ground floor window ( a good trad pre clean if its an initial - no chem.) Now and this is the key part. All of the water on the top window has now run off (while you were doing the the ground floor) so now is the time to rinse. I'm so slick, I can go to about 2 or 3 mill from the beading while rinsing. (without touching the frame!!! ) hopefully it will curtain or sheet of (you know the phyllic/phyfobic nonsense ) You should stay to about a couple of inches of the frame when rinsing you won't have the pole slickness that I have. But thats the key. Rinse about three or four minutes later

If you've been on about it for a while, it is causing some concern and is obviously an occurance on most of the glass you are cleaning. You said that you would try as I have suggested but you don't want to let the window dry after 3/4 mins. Thats tells me that you are being miserly with the drink. My windows would'nt be dry after 3 or four mins. It doesn't even need to be that long, just enough time for all of the initial wash to completely run off, then rinse, glass only inch down from the top.

i might try that but it sounds dodgey to me letting them dry before rinsing?  

okay, thanks neil i'll try that mate!

That could be it, GB.
The water is hitting that and running down onto the window. The spots could be mineral deposits from the concrete lintel. I`ve heard these spots and runs called 'concrete cancer'.
I`d be confident that`s the cause of your problem on that window.
And it`s not your problem really, rain will also cause it.
