OK.. the serious answer--

Post #356,792 by Ashton 4/24/12 4:35:35 AM 4/24/12 4:44:35 AM Reply	OK.. the serious answer-- Tektronx regularly washed their lab-grade scopes / test equipment, using a mild detergent called 'Kelite'--always followed by hours in a ~150° F oven (IIRC.) (with fan--but a regular home oven is also fine, with or without a fan blowing across the guts.) A Scary idea to unimaginative EEs then too! Others have used wood or even cardboard boxes cum fans and maybe heat lamps; a thermometer stuck in where appropriate. Guess a hand IR thingie is as good or better? ie Improvise. http://classictek.or...cope_Cleaning.pdf This is from 1976, but the points apply not only to their vac-tube units but later ss units, with caveats about covering the holes in power transformers where leads enter/exit. Some later scopes used delicate relay-fingers for attenuator switching and these are cleaned with bond-papaer and rilly-pure ("CP" = chemically pure) Ethanol. No computer relevance, that. Ditto for washing surface mount digital stuff of recent decades. (Yeah, good idea to remove HD, cd drives and such and hand clean those--HDs have breathers to equalize air px, not intended to be immersed!) If you digest this .pdf and allow for peculiarities of computer accessories, you should do no harm and should remove all scents (cigarette smoke was a frequent complaint after years of service, etc. back when Real He-Men drank Marlboros) You can bet that all mobos have been washed, following wave soldering--to remove flux(es) and make it all shiny. Nothing revolutionary here. Bon ~~Ami~~ appetit!--chefs know how to wash stuff, right? :-0 Should be a fun game; outsmarting a feline==Winning! Ed:PS--of course you Don't leave the power on, though unlike scopes it's mostly lo-DC all over, beyond power xfmr--now replaced with switching supplies, etc. But you knew that.

Post #356,823 by malraux 4/24/12 1:58:48 PM Reply	Or wait... I have this great idea for an experiment: Put the cat in the server, rig it up so that if the cat sprays then it releases an electrical arc, killing the cat. Then you'll have two cats superimposed inside the box, one of which is good, the other bad. Take the good cat out, and then do whatever you want with the server and the remains of the bad cat.
