The spots are caused by not cleaning the frame and rinsing enougth take a little more time and it shouldn't happen.

Try cleaning top rail first then by the time you come back to rinse in this warm weather it should have stopped running from the rail onto the glass. Just rinse from the top of the glass /emoticons/wink.png

thats good, bang on, unsure about anything, more water!!

Give it a good rinse afterwards /emoticons/biggrin.png

I had a customers house that did that constantly, dropped it in the end as it wasn't worth the hassle, ANY WAY I cleaned them the water would leave spots.
