I've been looking into the fact that Isopropanol breaks up surface tension of water.


I know some folks on here use it to stop there water from freeeeeezing.

But, doe's this reduction in water surface tension have any real benefits on cleaning windows?

I have experimented with 5 ml of IPA in 25liters of pure water.

Used it on both Hydrophilic, and phobic glass, and to be honest I can say I noticed any significant difference in the wetting out, or flow of water - except for water having small bubbles when it hits the glass.

I tried to convince myself it was having better wetting out on hydrophilic glass, but wasn't convinced.

I've just probably answered my own question, but just wondered if anyone has any other results?

where can you buy isopropanol from other than online . is there any shops that stock it .

[trevor perry]

 i to am just experimenting with using it and am finding it seems to move the dirt easier on first cleans and long interval cleans whether this is just the bubble effect of the water or whether it actually does clean better i dont know yet but will know better when we get some proper sunny days and i can watch the water drying out on the glass.

I got mine off Fleabay...

It does work,and leaves them cleaner betweeen cleans.I`ve been using it for about 4 months cold or not.

[d s windowcleaning]

nwh what amouts do you use say per 25 ltr of pure water .

[NWH]

I take it your using a trolley,i use a full whiskey glass in 5ooltrs and as i`ve said before you don`t have to keep adding it as it stays in the water when you top up.I find i have to add again when there are no more bubbles left on the glass,about every 2500 ltrs of water.I would fill the glass iuse and spread it over your barrels,maybe a cough mixture cap per barrel.

[d s windowcleaning]

no nwh i dont use a trolley i just put 25 ltrs of pure to find out a guideline for the amount i needed . cheers mate at least i now have a idea of the amount .

good stuff where do i get it from ??

Been using for the last 2 weeks,  a 90% plus version from ebay. Not sure if it makes a difference or not. Defineately doesn't make a diff to the tds reading though. Probably won't bother when used up what I have.

[trevor perry]

 i got mine of ebay and although i am still experimenting i do believe it works better than pure water alone , i put it in my 650ltr tank before filling and use about half a small cup full.
 i have found that with high windows where i rinse brush on the results are brilliant so am now rinsing brush on on all my windows, the results look great but will know better when we get some nice sunny days and any marks show up more, ps the tds stays at 000

Same here i,m experimenting did my house yesterday i dont do my house that often about every 3 months on average (when the wife is nagging to get them done) ,any way last time i did them
they had little drips prob coming from the seals this time nothing so i dont know, i bought 5 litres 90%+ off ebay  will start using it tomorrow ,£18 pound a go its got to show its alot better or after this i want buy any more

Yeh, that's what I think.

It has to significant improvements in cleaning to justify the cost.

[Ian_Giles]

I've heard of using this stuff before, but my only use for it would be to stop the water freezing in very cold weather, either from the water jets in the brush, or on the floor and so on.
Does anyone know how effective it is in that regard?
Or how much per 1000 litres you would have to use for it to have an appreciable effect??

As a wetting agent we used around 10% in the print trade with water cooled to nine degrees.

you can get it from maplins ian cost £10.99 for a litre . cheaper on e-bay but it all depends how soon you want some . its not effected my tds still 000ppm will be giving my windows a clean later if the wind drops so will let you no the outcome . 

[d s windowcleaning]

must say ive tryed this today and outcome was ok shine on the glass was great and if all my customers turn out the same they will be happy and so will i
