Went out today with my not so pure water at 19tds, cleaned my usual custys hoping they don’t spot to much but when I went back to the first few I done in the day (knowing there out at work) I was gob smacked to see no spots at all
so when I got home I done my own windows and they dried spotless to.
So my question is do you really need to get your water down to 000tds.
Before you ask yes I have 3 tds meters and they all read the same.
I hope tomorrow goes ok to as its now gone up to 21tds.
Bazz…
