You could always go to a Liquor store and get some Everclear, pure spirits.
However, cleaning of the Elecraft boards is NOT necessary nor desirable.
You never know what the plastics in today's parts will do in the presence of
solvents. Use of the cut off acid brushes will work, but only as long

I'll answer any other wah bottle questions offline.

To do it again you may have to blow into the jug to add some oxygen. Don't
In spite of my posting about paper towel and acid brushes,
I fully agree with Ron's observation that if one uses the
proper size and kind of solder there won't be a need to
clean your board/s.
I haven't needed to clean mine ...

I'm sure others will suggest many options although if you read the Elecraft
manuals you'll find, in bold type:

If you need to clean your boards you're probably using too much solder. Try
a smaller diameter solde
If you go to the drug store and look closely you can find 91% isopropyl
alcohol. The remaining 9% is water which won't hurt anything.
Works fine esp with acid brush previously mentioned.

There are/were many flux removal chemicals available,
but in today's over-protective society they're hard to
find. I treasure my stock of triclorethelyne (SP?). (:-))
"Rubbing alcohol" and a small stiff brush work well.
I place a paper towel on the board, between the brush
and the board, to soak
