Yesterday i only realized after i was finished that i had been cleaning with a tds of 016 for the last 2 days so paranoid i went back to the last 2 jobs letting on a left something behind and the windows were spotless thankfully

I would normally change it once it even creeps over the 000 range so to have cleaned for 2 days with 016 i thought i would of been making the windows worse but nope, so is there to much emphasis put on 000 for peace of mind cleaning and how far really could you go are have some of you went?

I've been cleaning with 20ppm for months now, my resin is spent and haven't bothered changing it

Have you lost many customers over them months?

[slap bash]

Just finish last month at 28 tds with no problems. The tds does not mean much its the composition of the heavy metals in  soluble form as a solution . E.g  If the water contained iron oxide the water would not spot on the glass but form a brown streak or just a brown tinge on the glass, but staining the frames. The spotting on glass is mainly calcuim oxide .

Was cleaning last week for atleast 3 days at 48ppm. Hadn't checked and it rose quicker than normal for some reason.

Was mostly commercial work, a lot of which we cleaned internally after the externals. No noticeable spot or runs.

Nope.
Did a first clean on an old Manor House today inside and out and they came up perfect. 000ppm is far to over rated let alone 000ppb.

Fair point lee, does anyone know how to calibrate a handheld TDS meter?

First you need a bottle of calibration fluid.  Available from most RO suppliers.  It comes with a stated ppm rating.  You dunk your meter in it and see what reading that gives you.  Somewhere on the meter is a tiny screw that you can turn to adjust the reading till it is the same as the known value of the calibration fluid.

On all perfect conditions, my understanding is anything upto 050 after that it becomes visible quite clearly.
Ive been working at 016 myself for last several days. Had to go back on one house to do insides and had to buff up a couple of windows on outside. That made ne panic and i checked all my other houses i did but they were all brilliant still. So i just made sure i was more diligent on frames and good to go.

001 tds can streak, it all depends what the dissolved solid is.

I only use 000 because I believe the spiel I churn out to my customers.

Cheers Nathan , so from what I'm understanding, if your windows are spotty , it's dirt left on the glass as a result of not rinsing properly- not because you are cleaning with 002ppm or 015ppm water because you can still get spotty windows even if your cleaning with 00ppm water

No it cant as you wont see 1 part per million with the naked eye, TDS is a measure of conductivity not a measure of what
can be seen with the eye.

I think he meant you can do a crap job with 000ppm and get streaks , the splash and dash guys

I believe thats it in a nut shell.
All my other windows ive checked. Some jobs i do inside cleans also. I like to do these once ive cleaned outside first and sometimes pending where im working, i may finish a street and then go back for somebody's inside clean. That way i keep an eye on the  actual quality of my work, rather than what i think im doing (if that makes sense).
But we all know bad seals, window vents, top openers etc etc can always release a trickle of dirty water once we leave. Or if we dont give a proper rinse (not just a splashing). If we work properly and efficiently, then NO we can work with water that is a little above 000tds.
Did a first clean today with a tds of 16. Went back to double check (as its one of many on same street i was working) and all was good   

[the king]

my water went to 026 once and the custmer complaned when i went in  side to have a look u could c spotting all over the glass i then went to next door and there windows were fine ive never had a issue befor with this job or since so 000 is all i use now ill let it go to 010 at the most now

[ChumBucket]

I've cleaned (albeit by accident) with 056ppm and achieved spotless results!

[Stoots]

mine spots at 004ppm

maybe it does at less i dont know, but i got a complaint, checked my  tds, it was 004, cleaned my own windows and all of them were really bad with spots.

highest ive cleaned with was probably about 20 by accident, now as soon as i see 001 i change resin, only confident with pure

yes it can, completely depends what the solids are.

you wont see 5 or 10 pppm with the naked eye, nor will you see 500ppm with naked eye, who can see solids in their tap water?

depends whats in your water, just because yours is fine at 001ppm doesnt mean someone elses isnt.

[Matt.]

I have been using just tap water, with no di and adding 5 ltrs of hd degreaser  per tank full of water !




But am only cleaning cladding
