very intresting

[heyoh]

I get what you mean, I wasn't actually telling this to my customers, I was just thinking about this thing the other day. To be frank I wouldn't tell anything to my customers or anyone about traditional window cleaning just to make it look like wfp is magic.

Btw I tried squeegeing a convo roof after washing it once... bad idea you can't mix the two /emoticons/smile.png

Pure water dosen't have any slip so the rubber can leave lines on the glass if you try to blade it off afterwards

Was thinking of squeeging a glass conny roof after wfp to see if it would be better, but thankfully read that comment from smurf. Was going to try a clean rubber,but not bother now.

You could always try trading the conservatory roof glass as normal attached to a pole using soap instead of pure wfp.

Maybe a porcupine applicator sleeve would give more scrubbing power on the glass then blade it off using something like a wagtail as would be easier to get into any pointy bits of the roof.

I done plenty of internal glass roof cleans using trad method but not tried it on the outside yet so might try it out on the next one to see how it goes.

Best to make sure first what type of glass it is as if your going to use an abrasive pad/porcupine sleeve and/or chems like ubik as if it's self cleaning glass might damage the thin coating on the top of the glass. Same goes when cleaning the frames and using a stiff bristled wfp brush

Just thought if after job was done on a glass roof and there was some spotting, you could use a unger indoor kit on a trad pole or wfpole with polishing cloth to get those spotty bits. Used to have a poster at my engineer job, which said "Think Quality- Do it right first time, every time". No ones perfect though, so if spotting does occur would it be an idea to try that, even tho its a pest?

Has anyone actually got a straight answer on how pure water actually works??

The spiel i got when getting mine was on these lines.....

''After producing pure water which eliminates all chlorides, fluoride, limescales and sediments, metals etc the pure water is then negatively charged via passing it through a ion resin bed. The pure water allows the water to dry spotless due to no contaminates to act as a seed for a spot to form around, and the negatively charged idea is that when the water comes into contact with dirt etc it attracts the dirt so the water can revert back to its natural state, which is inherently contaminated''

One of my bezzies works as a lab technician, and says ''i have never heard so much cr@p'' he produces deionised water for the medical industry for cleaning surgical instruments and is convinced that a surfactant is added somewhere in the process for window cleaning!!!

All i know is that it works, and there is definitely a chemical reaction going on somewhere in the cleaning process. To me it looks like the water is statically attached to the window if you will, its hard to describe but you all know what i mean.....especially on hydrophyllic

Theres nothing difficult about it Keir. You scrub the glass rinse off the dirt then there's nothing left there but pure water which dries clear. That's it.

Ah!!! But what you dont realise dodger is i am a massive geek and like to know how everything works down to the quantum level lmao

 

[Dodger]

Lol me too Keir but seriously that's the explanation right there. Quantum level is the water is pure the window is clean the water dries clear the customer is happy. No water feeling the need to get down and dirty again yadda yadda just you scrub you rinse it dries and as Herman might say that's aboud it.

being a trekkie gotta like that ....but on a basic level suppose dirt needs agitation to move it or else the rain would shift it which it doesnt and pure water being that it cant leave anything behind because there is nothing inside it as it evaporates away..you have already rinsed the dirt off the window..unless of course...you are naughty and go above the sacred line of .10 ppm...

yeh me likes the geekie positive charge thing too but i can only understand it when the great prof brian cox explains it to me...:rofl:

ps me only washes the car just as the rain starts.....

 

[heyoh]

ahhhhaa this on gardiner's website:

Many people, including our customers, say that the glass stays cleaner longer - why is this?

Firstly, because over a period of time, the frames gradually get cleaner, leaving no dirt for the rain to wash down onto the glass. Secondly, because it washes so efficiently with no detergents, it leaves no detergent residue on the glass, which would otherwise attract particles of dirt

i rest my case :laugh::laugh:
