This is so annoying- another newbie starting another negative rumour that will be passed around and come nack to us as a fact from customers.

No it doesn't rot wood.A right little ray of sunshine you are. What was your last job, PR at Ratners?

Hi Clive.

Been window cleaning 21 years, the last 3 years wfp. I always thought you tried to make informed comments.

at 25dc  viscosity [Pa·s]  [cP]
tap water             8.94 × 10−4 0.894
pure water           8.74 × 10−4 0.862     
   

But that's bullpoop anyway. It's not tap water falling from the sky now is it.

Well said
Rain water is quite close to being as pure as WFP, normally about 20 ppm, whereas my tap water is about 360ppm..

Steamed up windows........Bull

The units are sealed. Comprendey.

I have checked all this out with a glazier.
He almost laughed me out of the work shop.

They blow eventually from age or a fault not a bit of water however thin.

[Oakley Windows]

it is a lot thinner due to all the impurities taken out

I love these kinds of threads, all of a sudden window-cleaners are scientists/physiscists and molecular geniuses all rolled into one.

My favourite is why windows stay cleaner for longer with WFP, it might do, who knows, but has anyone any HARD evidence as to why, apart from what they dream up when they're bored alone at work and the imagination is in over-drive.

[jonisondell]

yes ok ive been rumbled,
the best one was, it liable to mist up sealed units, we only use trad on wooden windows, and someone asked a glazer brill!!
i cant believe 7 people voted for pure water rotting wooden frames.....

And I got into this business 'cause I thought window cleaning was a simple, uncomplicated thing to do

If your not carefull your brush can cause damage to paint work on wooden frames which can lead to water getting to the wood itself.

Wouldn't that be true of using a squeegee though? Scratching the bottom of the frame etc?

[Sir Squeaky]

Don't know, but your brush rips them to shreds anyway, so it doesn't matter.
