[Small but perfectley formed]

Cleaned my own Windows several times this week look ok when cloudy but the sun has come out  and is shining on to conservatory and there are lots of minute.spot s..
Hope most of the customers windows are dirty inside  .
Not always as good the results from  WFP as you would expect .
TDS of 5 ?

TDS of 5 well there you go lol,any Windows with cheap black seals that sit on and round the window can and nearly are always a problem. Try using clean water first then see how you get on eh.

The window where new in November 2016 no seals, can't see 5 ppm making lots spots.
Any other expert opinions ?.

[Dry Clean]

If the windows are covered in minute spots that can be rubbed off then its either the tds or your not removing all the dirt on the glass.
Did you trad the offending window to make sure they aren't ingrained hard water marks ?

[NWH]

000PPM is only just clean enough for the job I wouldn't even begin to question the results unless the water was at least 000PPM. Cleaner water than 000PPM or 000PPB does make a difference,I used to think an electric hose reel was a waste of time till I bought one but I would not be without one now. If you have recessed rubber seals and the Windows are of good quality I would look more towards the technique being used to clean them.

Fan jets can do this also this is the reason I never use them,spots galore I used to get with fan jets they put water everywhere except where you want it

Not if you rinse on.

In certain light you can see what an over spray and mess fan nets make,on cloudy days you can't see the mist of water in the air. I used them to clean jobs then used pencils on the same jobs next time round,with fans I had more spots than a teenager.

[NWH]

Also customers didn't like it I had a few actually say to me are you jet washing the windows nowadays,

[8weekly]

The other thing is that nothing looks perfect with a full sun on it. Plastered walls that look perfect can look awful when the sun's on them. Nothing stands up to full sun.

Not technique these window have been washed 5 times this week look fine except when bright sunshine maybe some contaminant in trolley ? .
My line of thought is wfp is not has good as we think.

[Small but perfectley formed]

8 weekly you are right ,but what would customer perception be when the windows look like this in bright sunshine.

[NWH]

You are using a trolley for 1 so you are transporting water to the trolley which could get slightly contaminated,also your water is above 000 like I say I would try cleaning with clean water first 005 is not clean enough for me personally.

If you are getting spots using fan jets thats down to your technique , not the jets.

[Spruce]

5ppm will leave spots on our lounge windows which are clearly visible in the early morning sunshine.
When the water gets to 1ppm I change the resin.

[Jonny 87]

As Sean has said have you trad cleaned the window to make sure it's DEFINATELY removable by cleaning?

[Jonny 87]

We had new windows and doors fitted at the end of last year. Cost us a small fortune, and they look perfect in normal sun or cloudy days, but in low sun and first thing in a morning they look terrible......

It's all on the inside of the unit. Dust, and even the odd finger print. Windows aren't as good now as they used to be. The only good thing is that there's no visible seals on new windows which helps minimise run downs.

I'd check first that it is actually a problem with you and not just the inside of the glass.

Not if you rinse on full bore.

[Small but perfectley formed]

[Dave Willis]

wfp is generally crap.
