I didn't get to see the windows in question. The only bloom I have ever seen is like a blue/grey film that is caused by nichotine. It would be impossible for pure water to cause this. You can see it on sunny days on the inside of the glass. It makes your applicator and the water in your bucket turn brown. I do an office inside where they allow smoking, it's bloody horrible stuff.

I think the bloom in question is on the outside of the glass and its a bit like a rainbow (or i have bad eyes)

I have a few customers with this on the glass and i don't think you can get rid of it.
I have tried everything.
So i doubt its the cleaning methods causeing a bloom but the glass itself.

Hope this makes sense half way through a bottle of peach snapps
