Homebrew PCBs

There was thread awhile back about using isopropyl alcohol as a board
prep cleaner. The typical stuuf you find is 70%, but you can also get
91%, which is what I buy as a wound disinfectant/cleaner of
contacts...but it still has a significant amount of water.

In the 2006 Allied catalog, there is some very desirable stuff:
99.953% pure anhydrous isopropyl alcohol.  Pricey for 3.5 oz (100 ml)
at $4.46, but not bad for 500 ml at $6.53.  So, it's available.
