I would make sure the water is reading 000 like I said before making any judgements,windows cleaned WFP regularly will show up any imperfections in the glass because of no residue no longer on the glass. As Dave said in general they won't be perfect and there's no way your gonna knock out the amount of work most of us do and get every window perfect,I'm looking for good results in general and by using the cleanest water I'm giving myself a better chance of that. I find the easiest time of the year WFP is mid October through till end of March,short days and minimal sun is bliss for us polers.

West  facing Windows always get a little bit more of a scrub also,anproblem house maybe a lounge or kitchen that faces west in the evening when they come home from work and stare out at the garden.

Not read through everyones post so if im repeating, i apologise.

Using 005 tds water will not be the problem at all. I like many have allowed the water to get higher and yes i clean my own windows. My wife is OCD on cleaning before anyone has a pop at working fast etc. Try eating // making a sandwich in someone's kitchen who has OCD and hou will know i wouldnt be able to get away with leaving spots!!

Anyway.......where abouts are the spots?
All over the glass?  More to the edges down the window?? Bottom half of the glass or more closer to the top of the window??
Depending where you can see the spots, generally gives an indication has to what the problem may be.
Is this on all your windows or just the upstairs or just downstairs??

Side point.....why have you cleaned them five times in a week for?? To practice your technique or to check what tds you can work upto or do u just enjoy cleaning windows??

[Dave Willis]

Been there, done that. I've cleaned my windows up to five times before with the same poor results in direct sun. Customers never complain. Trick is never check them, you'll only end up bi-polar if you do.

[The Jester of Wibbly]

Could it by a case of  a paranoid window cleaner?

Low level direct sunlight is a pain but probably more noticed by us. People tend to look out of their windows and focus their vision on the scenery. We tend to focus on the glass rather than the scenery maybe ?

Same when you scratch your car / van. You know it's there and focus on it too much. No one else will spot it.

wfp is generally crap.

Dave is right...

I have been saying this for ages....

Windows look spotty

What's your tds?

5

Duh.

Why do people use anything other than 000ppm ? Why would you spend all week cleaning windows and risk doing a bad job trying to save a few quid.

My windows spot at 3ppm

Use pure then at least you know it's not the tds and you can rule it out.

[Splash & dash]

I don't understand why people spend money on a system then use water with a + reading sort of defeats the object also the cleaning power is non existent.  0000 cleans so much better and quicker  , I found I could tell very quickly when the tds was rising just by how long it took to clean a window and the finished result you could defiantly see a difference , always work with a zero reading and never get complaints and doing my own windows never get spots Evan on hot sunny days , that's not boasting it's just the way it is , most of my customers if they saw spots would be on the phone straight away complaining

[rich fraser]

Are sure it's not just pollen settling on wet glass this time of the year. Have you got trees close to your house?

[JandS]

It's the tds....why do people advertise pure water cleaning then not do it and clean at 5/10.

Re fan jets.....
There are many different makes/types. Some, wide fan, some not so wide etc etc.
I have two types. Both on the same pump reading the one hisses out like a steam train whilst splaying wide, the other has a much narrower fan  and is far more controllable.
I like fan jets. Just takes a little getting used to.

I don't have a problem with fan jets either, as long as they don't convert most of the water to vapour. For me, Gardiner's red ones seem to have the balance just about right as long as you have good flow. I far prefer them to pencils. But that's just my preference.

[nathankaye]

On a perfect piece of glass and no dirt and using pure water to rinse it and leave to dry. You will only see spots etc at a tds of 050.
Obviously windows are not in this perfect test condition. But agitating and cleaning the windows properly and then a good rinse.........do you honestly think 005 tds will leave spots. I find only if the window seal leaks or is oily will it cause me a problem. But when you are aware of your customers windows you adapt how you clean them.
That was my painful new learning curve switching from trad cleaning to wfp. Its like becoming a new window cleaner again and having to relearn your customers windows. When you have done that and with good technique you eliminate spotting and errors.

Seriously people question my quality of cleaning because they think you need to flood a window with pure water to ensure quality. 😂😂  it does make me chuckle.

Then you have people convinced that vision in their water helps or you now need 000 parts per billion instead of million.
So perhaps that answers some of the above threads who ask why say using pure and allowing it to go above 000??? If using parts per billion than by that reckoning 000ppm isnt quite pure is it.
Its a little like packaging this drink has NO SUGAR  but just check those ingredients and you will find sugar but its a technicality.

Are you being serious ? the cleaning power of water doesn't change when filtered, its about removing anything in the water that
will be left on the glass when it dries, nothing more.

[nathankaye]

Above post...

This also makes me chuckle, how some feel its even harder on sunny days. I personnally dont understand it as i may be thinking way too simple on it. But if tap water dries on glass the water evaporates and leaves the minerals behind on the windows. Now if our water, (in this case pure water on ppm) dries it simply evaporates and obviously leaves no minerals on the windows. So regardless of an excessively hot day or not, the windows will dry the same........just makes me laugh how people say even on a sunny day.
Sunny days being a pain in the ass, only aplies to trad working and i remember those days well. Glad there behind me ☺

I would have thought colder days are our problems. As in the water takes longer to evaporate and so more prone to the elements. Ie, windy day blowing dust around that then contaminates the pure water and making a mess of your clean window

[C & S]

You will always have awkward customers complaining.
Im sure if I went back on everyjob I did today and looked I could find the odd run, bit left on a sill etc etc. Be it small it will be able to be found.
I dont worry about it, their windows are a whole lot cleaner than before you came, most have crappy insides anyway.
Direct sun will show this up and always will!
Vents dont help. They drip. Just dont wash them.simple moee trouble that its worth.
Every now and then you get the odd cutard who complaines like they always do. Re do or get rid...

[AuRavelling79]

Now come on Nathan, not only do you have to have zero parts per trillion but you also know that "aggressive" pure water also rots T - shirts in a day and vans within a month.

 

[Dave Willis]

Sunny days don't affect the clean it just shows up the poor power of wfp.

I doubt any professional would get an average window to look perfect in direct sun. WFP or trad.
