A recent post mentioned using alcohol as a solvent. This is a good idea and in fact I use alcohol in my electronic/camera lab quite a bit. But the type of Isopropyl alcohol available at the drugstore really is not the best type to use. I would suggest an Anhydrous Isopropyl alcohol as it is a technical grade and typically has less than 1% water. Drugstore Isopropyl alcohol will have from 10-30% water. Anhydrous alcohol works much better as a solvent and of course has no water residue. As a side note, Anhydrous alcohol could be used on live circuits as the lack of water gives it a very high resistance. As a further side note, if you add say 10ml of Anhydrous alcohol to 10ml of water, you will end up with less than 20ml of fluid as the mixing creates an exothermic reaction as the molecules overlap each other and create heat. Probably more than you wanted to know about Isopropyl alcohol! Bill |
