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

[dave f]

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

[mci services]

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

[dave f]

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.

[dave f]

yes its a pure freedom kit what makes you ask

[Sapphire Window Cleaning]

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?



Matt

[Sapphire Window Cleaning]

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

[wpclean]

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.

[dave f]

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

[dave f]

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 

[Jeff Brimble]

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   

[dave f]

  moore invesigation

[Jeff Brimble]

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.
