Homebrew PCBs

I think isopropyl alcohol would work too.
But i prefer ethanol because i have found it the better solvent in many  
cases, and the smell is much better too.
It's also more readily available here than IPA, but i buy both at the same  
place so that does not matter so much.

IPA takes on water easily i hear, i'm not sure but i think this is less of  
a problem with ethanol.

I dunno about the additives, all sorts of stuff can be added i have read,  
i'll write my supplier a mail maybe they can find out.
If you ever have gotten traces of the stuff on your lips (like you clean  
some sort of tubular item and blow through it afterwards) you
would have found immediately that you don't never ever want to drink that  
stuff. Even tiny traces of it taste awful on the lips.

I have not the slightest idea why in the US IPA seems so much more common,  
and here in europe ethanol seems so much more common.
IPA is practically only used at doctors offices in sterilizing pads for  
injections here, when i bought my first bottle not that long ago and took  
the lid off i got a very unexpected very strong kind of flashback reaction  
telling me that. I had never smelled it anywhere else before.
