Not sure if anyone else had this but today I had a couple of windows facing into the sun any way I cleaned then the normal way I do, one window always sheets the other always bead’s but they both always dry spotless. Anyway today as it was so hot and the sun was cooking them up the beaded window dried with spots. I cleaned it again with a higher flow rate as this always does the trick and when I came back same happened again spots. So I scrimmed it to remove them. Now my question is has anyone else come across this and how did you resolve the issue?
Cheers

Ps my water is usally luke warm due to me loading the van up over night and not starting till 9am thous the sun heating it up abit, now this would reduce the spots not make them. My TDS is 000 i wash my brush heads each time i clean a house as well. I rinse well.
