QUESTION: For the guys who bring their pure water or use backpacks

Great way to get started.

What’s your tds where you live ?
Did ever think about harvesting rain water then you can polish it with a Di tank ? Seems like you wouldn’t need a lot !

I have cleaned with 009/010 and had no issues with spotting. From what i have seen posted on the board.
Some have done 020 with no issues. 025/030 would be pushing it , imo

didnt know that was an option, thanks for sharing.
I live in an apartment complex so dont really have the space to set up a water catchment system without neighbors looking at me funny.

tds is about 300

yeah its weird but i have noticed the spots from 009 more often lately, doesnt spot all windows just one or two, i thought that maybe its not the water and some other factor but after doing deep investigation I am left with no other answer.

Yeah, but Mike they have a very different market in the UK. It is very common for households to get their windows cleaned monthly, there.

The windows probably aren’t that dirty each time they are hitting them if it’s every 30 days. They wouldn’t need much water.
