As the title suggests, what's the highest you can get away with and still do a good job?
Myself I stick to 000 ppm as then if I get any spotting I know it's down to the method not the water I'm using
they say you can clean at 10 with plenty of rinsing
Once mine rises above 0 ppm I change, because I only use wfp for high up, and windows that are too dangerous to reach with ladders I want to walk away from a job knowing its done to the best standard that can be achieved.

0 ppm here also
We work with 0 tds 99.9% of the time. I know we can go to as far as a tds of 4 but we can start to see traces of spotting above that with careful inspection. (I have experimented with a backpack and slowly 'contaminated' the water and then cleaned my own windows.)
I have often heard of cleaners who say they can clean with a tds of higher than 10 with perfect results. Either they haven't checked their results closely enough or, if thats a genuine observation, then the original water composition makes a difference.
For us we are on the North East coast and windows are very badly effected by the spray that gets blown in off the sea. So we make sure the water is always at 0 and we tend to over rinse to make sure of a spot free result.
007 for me. A bloke on another forum uses tap water of something like 028 and blades any windows that spot. What a numpty
yeh I clean at 7 tuffers, mind I am always stiring the DI resin as soon as it creeps up, which drops to 000
I clean at 2 or 3 but I can let it go to 5 or 6. Once cleaned at 44 for a week and only got 1 complaint... loyal custies...
7 to 8 for me although did once clean with 11 & never got a complaint. Was expecting it but checked the windows next day & were fine.
