Alcohols and water are both polar and mix at any ratios.

The azeotropic mixture of water and ethanol at atmospheric pressure is about 95%. It is readily available as 190 proof or as 200 proof reagent grade.

The azeotropic mixture of water and Isopropyl at atmospheric pressure is about 87.9%. It is readily available in 91 and 99 percent mixtures. I infer that the 91% grades are azeotropic and done under vacuum.

need a nap after that explanation Brother..

Wait until he explains the second question.

Thanks for that!

GrayWolf why can you clean remotes and stuff in alcohol safely, but not water?

For starters, to use water, the contamination must be water soluble, and greases and oils are not.

For another, the dielectric constant (polarity) of water is 80.1, while Isopropyl is only around 17.9 and Ethanol 24.5. On the dielectric constant scale, anything above 15 is considered polar, and Isopropyl barely is. Check the column headed Epsilon for dielectric constants.

Isopropyl is widely used to clean circuit boards.

I have heard of folks cleaning computer /laptop keyboards. Like where a sticky beer/drink spilled on keyboard. Soak with alcohol.

I heard Joe spills beer all over his and his M key still sticks

 

[joeb631a]

I figure he can explain why and how that works because i know it works i just dont understand how.

Anything to do with the earths rotation or the earth being flat and few speed bumps

Thanks. I know it sure cleans my earbuds and remotes good. And it doesnt hurt the speakers on my earbuds at all.

Maybe you need a solvent that will dissolve organic matter

Hoarder , they should make a show

It could be Unc in which case I would need another cup of coffee and an additional snack source

He said it is the creamy wht foam that came from the head

I use 99% iso for everything vape related.
We buy by the gallon from Amazon and usually go through 4 gallons every two years.

Iguanas can be killed year-round and without a permit on 22 public lands in south Florida and on private property according to the FWC. I understand that, if properly prepared, it's not too bad to eat, too.

this is a good place to buy bulk if needed…we have order from them in the past

Thats the best stuff for cleaning electronics. 99%
Anything over 90% is good.
