The "denatured" type works ok, or get 91% and add distilled water to it to
raise its flashpoint.. This way then, you clean the board with a flux brush,
blow dry it with a hair dryer or a fan or something, and use more distilled
water if you get water spots or mineral deposits..... 91% alcohol will put
you in the hospital with the much feared invisible flame..
