true hydrocarbons are excellent solvents but highly dangerous and are toxic

If you add salt (1/4 cup) to rubbing alcohol and mix it when it settles it will separate into alcohol and saltwater. Then you can just pour off the 90%+ alcohol into a new container.

This is useful if you cannot find 90% isopropyl in your area but it's more expensive than just buying the stuff.

Contrary to what has already been said you don't need to make a salt solution first, and you don't need to know anything about molar concentrations (molarity).

I never use any sort of alcohol. A dry paper towel is more than enough.

and you don't think you can scratch the surface/leave residue on the surface with no agent to remove the thermal? just wondering about that.

It's not enough to remove the old TIM you just assume it is because you don't know better.

lol for those that cant find 90% alcohol how about some 99.0% stuff and its cheap too go to any truck stop or big gas station rest stop , and ask for air brake anti freez . a 4L jug will set u back $10-$15 and come on its 4 L ur set for life lol

but some times alky just wont cut it i did enoghf rroded 360s to know that alcohol is ok , but acitone is like peeing on a snowman melts it cuts it like a hot knife threw butter , but with acitone u have to watch out dont go all nuts cause it will eat /melt most rubbers and plasticks paints , so now if u take off a heat sink and the stuff is all crusty , give it a shot with some alky if its geting u nowhere fast grab the acitone , but waite u dont got any wel its ok grab the gfs nail polish remover its acitone with a nice perfume and not only are u abol to get get rid of the old crysty goop fast but ur computer will smell nice too

I use 70% just fine.

Shurik work on your grammar and spelling please. That was painful to read.

FYI, I get my 90% at wal-mart, they carry 70 and 90.
