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?
