Really, you gotta be yankin our chain right?

Road Warrior is not really kidding.. many of the products he listed are only the isopropyl alcohol/variants and sometimes are 'a little watered down as well'
I have actually used 99% alcohol to help start my car similar to starting fluid, It idled a little rough at first but it works.

91% is what I often douse my motherboard or other components in (SOAK them), and I've always had working parts come out of the mess. I wouldn't trust my parts to less than 91%.

i've been to a few stores searching for the 99% but the highest i can find is 91%? is it still safe to clean the heat sink and cpu with 91%

NO! You could be KILLED and make the Earth to break out of its orbit and hurl into the sun!!! Which is more important to you, a clean heatsink & CPU or the fate of the entire planet?

I've read that the only reason alcohol more pure than 70% is needed for cleaning purposes to prevent metal from rusting, and I've noticed that 70% leaves drops (of water?) behind while 90% doesn't.

99% pure alcohol can be bought semi-easily because I have a bottle of Medalist brand 99% isopropyl alcohol distributed by McKesson (dairy co.), NDC #37938-005, that I bought a long time ago from a drugstore chain that no longer exists in my area. Denatured alcohol should also be 99% pure.

Nope.

I use 91% and it dries up pretty fast, I wouldn't be worried about 9% water.

Does anyone know if 99% ethyl alcohol is alright?

Yes, it's great!!

Especially, with some orange juice!

Where can you find 99% ethanol?

I use "100%" pure acetone. It works pretty well, and easy to find. I got it from Wal-mart for a couple bucks.

Just buy a bottle of Everclear. When I was installing the XP-120 two weeks ago and didn't have any isopropyl that was above 50%, so I asked dad if he did, and he said (as a joke) to use Everclear because it's 190 proof(95%). But he had a gallon of Denatured Alcohol, so I just used that.

?? my local grocery store (pavillions) has 99% and they even sell it in liters. I just got a big bottle and I've been using it on LOTS of things. 99% is defenately nothing special and you should be able to find it at most of your local stores.

I'm sure 91% would be fine. I also got my 99% at Meijer for $1.17, you should check it out!

 

[XTTX]

Not really, I bought some from Meijers here, Meijer brand 99% isopropyl Alcohol, $1.17 a pint. Its good stuff. They had 71% and 91% too of other brands, but they carry the 99% of their own brand, so thats what I got.

Oh sweet. I just moved to Chicago, and we got a Meijers near by (none in New York).

It eats through plastic and other things, though.

Depends what plastics correct? I believe Polypropylene, Polyvinyl Chloride and High density polyethylene is not affected.
Don't quote me though.

 

[larrymoencurly]

You can find how materials interact with chemicals from the Cole Parmer Chemical Resistance Database and the Harrington Plastics Chemical Resistance Guide.

Acetone, lacquer thinner, and carburetor spray are nasty to PVC, ABS, polycarbonate, and styrene, all which are used for computer and monitor cases. Polypropylene, polyethylene, and PET (soda pop bottles) seem to be inert.

Acetone does like to eat various plastics - I wouldnt trust it. Personally isopropyl would be my choice.

Generally in an organic lab acetone, light petrol, water, and ethanol are usually the chosen solvents although this can vary.
