Hard water on second story outside windows?

Trad Window Cleaning
1

Hey all, did what was supposed to be an easy under one hour job, cleaning 50 total french window panes. However, it took me nearly 2 hours because the windows were so dirty with what appeared to be hard water. It certainly acted the same way as hard water, the soap just wasnt super effective. I had to basically wash each window 3 times, while also using bronze/0000 steel wool, and the detail work was so tedious.

What would cause hard water up there? I told the owner and he basically said he had never heard of hard water on windows, though he thought I did a good job (thankfully)

Any thoughts, havent dealt with hard water in window cleaning before. Crap sucks.

What region are you located in?

Could it be the opposite of hard water; acid rain?

I’m near Minneapolis, I havent been here long but not sure Acid Rain is an issue here, could be though?

I use A1 harvester stain removal from Cleaning Spot. It works a treat. Expensive to buy at about £28 per bottle bit it lasts and it’s effective.

Sorry. Previous post spelling mistake. Hard water stain removal using A1 hard water stain removal

On this type of job I inform the homeowner of the staining and let them know on this type of cleaning there is additional pricing involved. Hard water stain removal is a restoration process not a cleaning process. I charge a separate fee for that, somewhere between $25-$40 per pane on a DH.
