got a spotting problem with a couple of houses only had two cleans rinsed well newish windows. any remidies ive only been wfp a couple of weeks ive advised it will take acouple of cleans so ime hopingi dont get any more wingers ???
-
dave it could me a million things, we need more info on set up, method of cleaning, flow rate, type of window frame, weather and probably some more info
-
hi flow rate 27 upvc widows ,dry weather condition ro and di set up all is new gear. also window cleaner was wfp cust y gave him the bullet same reason im just thinking it may be that its a old house with stone sills not upvc just wonder if its dripping onto windows after ive done but i make sure i do all the tops but wait till they stop dripping or i dont rinse properly oh its aquaphobic glass
-
on the windows that spot is there any openers/hoppers? vents? do you rinse off the glass and how far of do you hold the brush, is it a mono filament brush or the other soft one ???
have you looked at the spots are they in a line dribbling from the seal?
could it actually be hard water stains that don't show as much when you are trad?
honestly there is a thousand reasons why something can spot, so talk us through the clean
-
hi theres no vents vitkan medium brush hard to tell if its commig from seal windows look fairly newish
-
Is it a purefreedom set up? if so crank you flow controller up to around 60

27 flow might be a little to low , try to rinse more.
-
yes its a pure freedom kit what makes you ask

just thought it might be given your using it on 27, thats about 1 litre per minute, I find it best to have approx 2 litres per minute, are these windows leaded?

turn your flow controller up to 50-60

ill try that on afew moore windows although it seems the rest have been ok sofar may go out tomorow and catch up to windy and rainy over here in west yorks
-
dave what i was getting at is pure water doesn't cause spotting but something you are doing does, the others could be right and crank up the flow might help. it is all trial and error, it is hard to know where someone is going wrong because it could be so many things, and the internet is the hardest to explain it. only dirt or old detergent causes spots IMO, so you need to combat that
-
Where in west yorks are you, might be able to help ?

You have to put your Sherlock Holmes hat on and work out where the spots are coming from. There has to be a reason. It can only be dirty water dripping or running down from somewhere.
-
i agree the custy sacked last guy who did wfp i explaind that it would take a couple of gose to get it sorted i had don trad on it for 6 months before goining wfp
-
gonna crank up flow rate start rinsing big time ive noticed theirs a lot of aquafobic glass a bout on my round maybe its a combination of that and not enough rinsing ???
-
I can pour a bucket/glass of pure over glass to rinse without touching the frames and still get spots so if its not the pure water where do the spots come from ???

I agree but have been trying to find a cure for 12 years, someone take over !
Xxxxxxx Oxide is the only thing I have found that makes phobic glass sheet.

Spotting and where they come from is obvious once all your equipment and technique are sound. Airbourne dust particles, even in a mild breeze there are millions of them, invisible to the naked eye. They float around and leech onto your wet glass, water evaporates and dust particles remain in the form of spots.
Science has not proved this of course, too irrelevant I suppose. So I have decided this is my down to Earth thesis. And it does make sense. ;D
-
Clean spotting glass with a wfp then squeegee it dry, then pour pure water over it- hey presto no spots, dust or otherwise ??
-
Dunno Jeff, why pour pure water over bladed glass? I often see spot like marks on my trad stuff as well when I next clean them, so it's not just confined to wfp. I recon airbourne dust.
-
Yes its the next time round that they are often visible, especially when the sky is blue and the suns at a low angle, maybe I think the spots are left behind to dry and then maybe the airborne dust that Ronnie mentions sticks to the semi sticky depoits left behind but over a peroid of time they get more spotty ?? ???
-
If you're getting random pattern spotting then you have just not rinsed enough *. If the spots are in a fine line then its almost certain that its running out of a seal.
* There are window frames that you will never be able to rinse enough. Poorly maintained wooden frames will always leech dirt, the trick is to stay off the frame wherever possible.
Twin openers, another bad one. With some its possible to give then a good scrub and you get no run off coming down the centre of the frame. WIth others no amount of scrubbing the centre seems to remove all the dirt. If you can identify one of these problem ones its best to keep the water away from the middle of the openers.
Some people say turn the water flow up and rinse. I find that on problem windows the force generated by the extra flow exacerbates the problem and a lower (therefore less forcefull) flow targetting only the glass produces results.

run down off brickwork above is a big one with some houses. Oxidised frames is another

another old topic i know but i feel like im getting some where reading these!
whats scary is that jeff one of the window cleaning masters after 12 years on the pole is still shaking is head about it all!
what he says in this post describes my problem perfect. axcept he did not mention that the spots are still there immediatly after you clean then again in other sords its perminant spotting
-
If the water is at 000tds and the glass is still spotting (and it does despite what others may say )then its a glass problem, I just wish the manuf./installers would stop messing about with it and adding coatings and polishes etc.
On problem windys you could just trad over the glass afterwards without any detailing, which is a shame when you have paid thousands for your kit, wonder why the suppliers always say no problem with our system ?

thanks jeff.
like you said if your rinsing well with decent flow rate and 000ppm it HAS to be the glass!!!
im sure if the custys see these spots in the same light and angle im looking at them in now they would sack me off for a trad cleaner and who can blame them! :-[
