Alcohol warning - Erik Wahlin - 07-05-2001 I believe you need to be careful when using alcohol around sesitive electronic circuits. Re: Alcohol warning - Tony Duell - 07-05-2001 Alcohol may be polar, but it sure isn't ionic, which is what really causes some liquids (including impure water) to conduct. Re: Alcohol warning - David Smith - 07-05-2001 Isopropyl alcohol is a standard cleaning solvent used in the electronics industry for decades. There is no problem with it leaving conductive residue. It can cloud plastics particularly in its conventrated forms. I use cigarette lighter fluid to clean adhesive residue off of cases without any problems. It is also used with red jewlers rouge to polish scratches out of the red LED lenses. Always test a new solvent on an inconspicuous place when it doubt.
Propanalol is a standard ingredient in most lens cleaning solutions and I have never had a problem with it attacking plastics. It is a rather gentle solvent.
Re: Alcohol warning - Luca - Switzerland - 07-06-2001 It depends from the kind of alcohol. It seems that beer and gin tonic are not the right ones for electronic circuits, but you can test them on texas instruments calcs !
Re: Alcohol warning - Tony Duell - 07-06-2001 No, not gin or vodka :-). The stuff I use comes in a spray can labelled 'IPA' (Iso Propyl Alcohol, which is the old name for propan-2-ol), and Re: Alcohol warning - Miguel(Denver) - 07-07-2001 I can vouch for the baddness of beer in/on/saturating/electronics...I can also say that the next day, a little more level-headed, Isopropyl alcohol does wonders. For the device, NOT for your head!!!!
Re: Alcohol warning - Reinhard Hawel - 07-08-2001 I prefer testing beer and gin tonic by drinking it. Unfortunately, normally there's no alcohol left after I found it suitable ... :-(
