It still amazes me how some people clean with 4 or 5 or even 10 tds, might be ok for hydrophilic glass in the shade, but combine hydrophobic in hot direct sunlight at 10 tds then really, your asking for issues.

Really need to be on top of your quality control at this time of the year, especially if you are having a major push forward with new cleans, do em all wrong and you might as well say, we are crap at what we do, lets announce that so everyone knows. 

I would never try to do 10 1st cleans a day, max per day on 1st cleans for me is probbably 4.

Under perfect test conditions, it isnt until a tds of 050 that spotting occurs.
Yes we dont work in test conditions, but once the window is clean and 006 water that im currently using, is left on the glass in full sun or not (it will dry the same either way) will be ok and is ok.
Many use water even above this and once I had a time where mine got upto 015 and was drying ok. If its a problem then all of us who dont sweat about the mysterious magical 000 would be foolish to not take heed and yet our results speaks for itself

It’s not just about not spotting , the closer to 000 your water is the more aggressive the water is at desolving  dirt and the water absorbes it better and quicker if you are using water at anything above 000 the higher the number the lazier the water is at desolving dirt so the more likelyhood of getting spotting increases unless you spend more time scrubbing and rinsing which isn’t cost effective in amount of time taken or the amount of water used : this is the whole reason that pure water is used if it’s above 000 it’s isnt pure

That old wives tale came out back in the early days to help sell wfp, ( remember hungry water lol ) we don't dissolve the dirt
we agitate/loosen it from the glass/frames and then rinse it off.
We filter the water to remove dissolved solids that would be seen on the glass after it dries nothing more, if 000pm was a must have then we would all be in trouble because our cheap tds meters are nowhere near accurate enough to measure it to that exact level.

I'm surprised  you  still fall  and believe in this rubbish reflections you come across as an intelligent person.  You use water that is purified to a certain level and that's it.  To say at 0ppm your water is "pure" and above is not pure is  a silly comment to make, what if you  could measure your water with ppb tds  meter how pure would your 0ppm now look. Next you'll be saying hot cleans twice as fast 

[Marc Stock]

It isnt rubbish. Aggressive water is used in manufacturing, and as high quality de ionized water has given up all its free ions any crap that the water comes in contact with the water will absorb it. Its been used in integrated curcuit design for the last 50 years, and it was in fact the key part of making computer chip manufacturing possible as there was no other way of cleaning silicon substrates in an effective enough way. So the invention of DI water in fact enabled computers to go from filling a room to filling a size of your fingernail.

The computer industry uses ultra pure (parts per billion or part per trillion) for no other reason than the removal of as many contaminants as possible from the water, its aggressive nature is due to it having a low PH acidic, luckily for us 0ppm tends to sit around the neutral to only slightly acidic mark so wont do any damage to what we are cleaning, it might absorb salt or calcium slightly better but it certainly wont be to any noticeable degree and a few ppm above zero wont effect this.

[Marc Stock]

Parts per billion is marketing jarjon designed to empty the pockets of gullible window cleaners...and its like saying reading your car speed in kmh is superior to that of mph. It makes no difference, the speed is the speed.

If your reader reads 000. Its 000. Doesnt matter if its parts per billion trillion or quadrillion. Zero is zero. It only matters when the reading starts to count up.

Secondly, people in the water purification industry dont measure in parts per million as thats an estimation using a forumla of the calculated conductivity reading and the current kinetic energy of the water ( temperature)

Pure water will have zero conductivity. This is measured in microsiemens and really if you wanted pure accuracy on your pure water you need to be reading in microsiemens.

Don’t think it’s an old wives tale one of my customers is a chemist and took great delight in telling me all the scientific facts as to how it actually does it , if you want to get really complicated you can go into the - 000 scale I thought that was a load of rubbish ionics used to sell systems but according to this guy it’s true and is used in many industries for cleaning surfaces without using any chemicals he did explain it but was way over my head 😂😂😂😂😂

Ime not going to get into some scientific debate but it is a fact that this is the case if 000 is taken as pure then 001 is starting to be dirty : yes only slightly I admit but the higher the reading the less cleaning power the water has this is how ppb works do we need water that good to clean windows probably not but will it clean better and quicker yes it will it’s a scientific fact weather ones believe it or not I personally don’t care what ones use if they want to use water with a tds of 100 crack on as it will result in us getting more customers as the finish they get will be very poor there are a number of cleaners in my area who boast that you don’t need water with 000 and they regularly use up to 035 and wonder why we are picking up a large percentage of the customers they won’t accept that there water is a problem but when you look at the properties we clean and then the ones that they do there is a huge difference that’s a fact people do notice it that’s how we get a lot of our work they say why does my neibours windows look so much better than mine you both clean it the same way I then explained it’s about water quality we get around 40% of all new work beacause of this 

[nathankaye]

Well all this has been fascinating to read im sure 
But these facts and figures do not take into sccount the force in which the water comes into contact with the contaminants on the glass, not the agitation of the brush and certainly not if the water is hot.
So in conclusion, im going to stick with my 14 inch dual trimmed six jetted brush and using hot water slightly above pure with a reading of 006 and be a content little worker 

[alank]

I fill my resin vessel pump water through it if it reads zero up to about 10 it gets used end of

I am in full agreement here.

I have picked up work from many other window cleaners in my area, and the biggest issues with them is 1. Tardiness and 2. Rubbish results.

I always always keep my water at 000.

And i keep to my schedual.

And i am reasonably priced for my area, one firm wanted £90 for a 3 bed semi here recenty, and i have watched them work, scubbing and rinsing the same window for 20 mins nearly, complete amateurs.

[Simon Trapani]

I double di after RO to cover all bases and get everything I can from my resin.

Why were you watching them for 20 minutes Marc ?! Have you not enough work to do 
Also
•2 - how do you know they charge 90 squids

Just askin like .....

I drove past them on Thursday to a job, did my job then diving onto my next job the same guy is standing there 'rinsing' (this always makes me laugh) the same window i saw him doing 20.mins earlier.

And i know what they charge, because yesterday i got a recommendation from one of my customers,went and  did the quote the guy was really happy and as a result i also picked up his neghbour too, he then told me some of the ridiculous prices hes been quoted, and i asked him what company it was.

Fair enough 

[nathankaye]

So to clarify, are you simoky saying that spotting on the window is purely down to water tds? That the complaints about previous window cleaners they have tried and the conclusion is down to the water?

Ime I would say not

[the king]

my water was 026 once last year buy mistake  and i was cleaning a job the lady came out and said her windows were spotty all over ,i went to have a look as they were allmost completly dry and i couldent see any spots till i went inside ,the windows all sheet on this job to had to squeegee the windows luckly it was a bungalow , checked next door and they were fine ,so it depends on the glass your cleaning,i came home early cleaned my windows and you could see faint spotting, i filled tank with pure and water was allmost pure as there was 026 water left in tank ,cleaned my other window on french doors and it was spotless ,that was 011 water so now i let it go to 006 then change resin

[Dry Clean]

Rain wont be 000ppm when it hits the glass, should we clean in the rain or if rain is due on the day ? some of you guys cant see the wood for the trees. lol

No your right, thats why i get hundreds of complaints and have to work the whoke day again that i did in the rain,,,,,
