From the progold posts below, I tried to find some 99% isopropanol in my local drug stores but only found the followings: 70% and 91% isopropyl alcohol. There were also some with rubbing alcohol designation. And some ethyl alcohol. I ended up buying the 91% isopropyl. Is this stuff ok to use to clean old circuit boards and jacks? Thanks. T.

Look locally for a compounding pharmacy. Typically, they'll be located in the immediate neighbourhood of the local hospital.If they dont carry it in stock....they can order it on short notice.
Mine ordered me a 5-gallon bottle of it overnight for a paltry sum. Something like $8 or $9 as I recall.

Pour some in a clear glass and let it evaporate and see if there is any oily residue, as may be the case with some "drugstore" brands of isopropyl alcohol.
Thanks for all the great replies. I think I'll save some money and try out the 91% isopropyl. Can't afford the $20/quart price online. This is as much as the progold or other contact cleaner stuff.T.
Go to Trak auto or equivalent.
ISO-HEET feul system dryer is 99% Isopropanol.
It costs $1.99/pint. This will last you years.
Spring another couple buck for Q-Tips, and you're set.

'Isopropyl alcohol' is another name for Isopropanol, and 91% will just do fine - the rest is water, which will not hurt your valves either.Regards,

Also 190 proof(95%) grain alcohol makes a great cleaner. I've been using it for years with no ill effect except my liver falling out. Many musicians use it for cleaning pads on woodwind instruments which is how I found out about. Cleans nicely and leaves no residue. Should be available at any fine liquor store unless illegal in your state.MD

A fifth of everclear runs me $13 and lasts a lifetime. Vodka cheaper than that comes in plastic bottles which I ain't buying. Especially if I want to have friends over to listen to my system. ;)I'm not sure if vodka would be a good idea. It has a lower percentage of alcohol which means you got more of something else in there. Not sure if it is pure water or what? I would worry about it leaving some weird residue. Also, I wonder if vodka has sugars left over from the distilling process since it isn't distilled as long. I would wonder what the sugars would do to metals.
Are there any chemists or mettalurgists out there who would be able to answer these questions?
Let me go out on a limb and strongly recommend not to use a fine bourbon for this task.
