i wish people would stop treating pure water as if its a chemical, what you experienced is called condensation thats all mate!!!!
i did a house monday it was suny quite warm in the sun and the water was steaming on the brick work is this normal wasent expecting it windows was ok though
if the glass is warm and the sun is directly on them then i would sugest that you rinse a lot more than normal or they could dry spotty, i find it best to rinse and cool the glass first then clean as normal and then give a final rinse.
