Hydrophobic glass help

P

Pickingpaul

Ive been wfp cleaning for 6 months now and its going great using home made trolleys.

I noticed everyday i work the odd house or houses have hydrophobic glass varrying in degrees of hydrophobia. I thought after a few cleans it might sort of get better some how but it seems the same and im Starting to remember which houses are like it.

So how do u clean these? Im having a whale of a time cleaning glass that wateralls and i know they are drying close to perfect, but i can see on the hydrophobic panes that there is lines of dots of dirt that even when i scrub with the brush doesnt want to move yet alone rinse.

So there must be some special tricks to doing this glass? Ive not had any complaints about it yet but i like to do my job well and it annoys me that i cant get them to the high standard, ive been sort of turning a blind eye to it i guess.

 
Its mentioned here and there and i had this advice from Diwrnach yesterday, thanks mate

"Yeah I hate that glass, it cleans OK you just have to rinse it a lot more with smaller moves down the glass, it is a right pain though and no idea why it is like it.

Anyone know why some is like it? you can even get two panes on the same window one is fine the other isn't?"

Interesting abs, ive not heard how its made before, im looking n youtube, i seem to remember perry tait talking about it once in his future of cleaning videos

Scrubbing the glass with a bronze pad, anyone tried this? Seems a pain doing it to every hydrophobic window on ur round but i guess once its done its done.

 
Does vision help with hydrophobic glass?
I thought it was going to make phobic act more like philic. It hasn't for me as yet. Kevin, who makes it told me that over time, maybe a couple of cleans that it can.

 
I am told its put on in different ways. Most is dipped in a chemical. I hate the stuff, I find fan jets are better with it, on a higher flow.

I watched a USA clip where he rubbed the glass with copper wool and this removed the coating. Thing I will give it a go. Is this a pan cleaner in a metal ball?

 
For phobic glass I find high flow rate and fan jets works best for me. Some have also switched over to 10 lpm pumps in there van mounts now as they say rinsing takes no time at all now. I wonder why? /emoticons/biggrin.png

As for the vision additive I have not tried it long enough to see if it makes any difference.

It’s the other way around pickingpaul, Its varying degrees of Hydrophilic – all glass is hydrophilic; when you mention hydrophobic glass, its really just glass that is - less hydrophilic than other glass. :thumbsup:

Other things to consider - are the coatings on glass to make it even more hydrophilic. Now we seem to have wetting agents, added to the pure water.

Water temperature, which changes the surface tension of the water (heated systems, or the summer, winter seasons etc) the brushes bristle type, the water flow rate, and cleaning method, (these are relevant) the amount of dirt, and type of dirt on the glass.

You work with what’s within your control. The level of how each pane of glass is hydrophilic or isn’t, is not within your control.

 
That confussed the hell out of me richard... Mind you I am a paddy /emoticons/biggrin.png

Not to worry as at least the vid I posted shows that fan jets work better on phobic glass than pencil jets.

 
Sorry smurf didn’t mean to confuse things; I thought it obvious glass is hydrophilic. Otherwise all the other things you can do to make water sheet better wouldn’t work on glass, like something simple as spraying the water with fans jets, rather than pencils.

Fact is though it really doesn’t make a difference what the level of Hydrophilic is on any particular pane of glass, you can either clean it spot free quickly, relatively fast. Slow or you can’t do it (yet).

The type of glass isn’t and shouldn’t be a problem when you’re working.

 
if really not happy with result mate could you just trad them especially downstairs windows i do this on really bad hydrophobic

 
I must admit I have on a few windows before I used fan jets and wacked the flow rate right up./emoticons/biggrin.png

Using chems as a boost on filthy phobic glass I find also helps too:rolleyes:

 
clean them properly then rinse from top to bottom

if I think there is problem with bleeding top rubber seals ,I then dry wipe the top seals

must say that hydrophobic glass looks xxxx when first cleaned it takes some convincing the custys that it will dry ok

this is the main problem wiTH WFP

If the vision works what a winner will make all the difference

Yeah i can understand what you mean there Richard, but it seems to me that within the window cleaning community people refer to glass that repells the water into little streams rather than sheeting as hydrophobic glass although as u rightly point out its still hydrophilic but at the negative end with regards to wfp cleaning. That said i will continue to refer to it as hydrophobic glass otherwise no one except maybe u will know what type of glass im talking about. I'm Not going to start saying "barely hydrophilic glassis causing me trouble" /emoticons/tongue.png

You say all glass is hydrophilic? Even when it has a nanotech coating?

Fan jets eh? Do u use these smurf on the mushroom windows? Im (surprise surprise) using pencils at the moment, do u see any negative reason to using fan jets on hydrophilic glass?

And by hydrophilic i mean none repelling of water glass that sheets rather than pi££ing me off glass [delusional]
