But for what your talking about, its just that EtOH is just too hydroscopic to give up the water (likes water too much). If you can find it, isopropanol, 2-Propanol, or isopropyl alcohol (all the same stuff but different names), is really the stuff to use for this. I use it on my tape deck heads. DONOT use ammonia or any other caustic substance, it will start eating at the metal. #include -- ----------- Scott Presnell Eidgnoessische Technische Hochschule, Zuerich (ETH-Zentrum) Labor Fuer Organische Chemie Universitaetsstrasse 16 CH-8092 Zuerich Switzerland. uucp: ...seismo!mcvax!cernvax!ethz!srp (srp@ethz.uucp) earn/bitnet: Benner@CZHETH5A
