No, they're not the same. Ethyl Alcohol is the kind you drink. isopropanol is rubbing alcohol, and Ethylene Glycol is antifreeze. The two latter ones are deadly poison. All will disolve diferent chemicals. I keep all three around for various uses.....hehe....hic...g

Subject: Re: [Homebrew_PCBs] ipa, ethyl alcohol
hi
i read some information about ipa.
i have read of it often for cleaning/solvent etc.
i only saw a bottle of it once (with a terrible misspelled label on it).
this was a strange brass bottle which had some kind of pressure tight valve which to pull back and then
the ipa flows out.. so i assumed this may evaporate very fast. is this right?
i never saw it sold in any shop but found it as isopropanol which is only another name (is this
correct?) in the list of a local chemical supplies shop.
i also read it is used a cheap substitute for ethyl alcohol.
but if it is only a substitute for ethyl alcohol i would rather use that.
it is sold as "spiritus" here, which is ethyl alcohol (somewhere betewwn 96 and 98%).
it is made undrinkable by some chemicals and so rather cheap because the taxes for alcoholic drinks
don't apply.
does anyone know what the differences (in using) of the both alcohols are and if ethyl alcohol ay also
be good for cleaning the old ink out of the cardridge?
regards
stefan
