Cleaning Electrical Contacts
« on: Fri, 08 March 2019, 19:46:56 »
I use DeOxit D5 and DeOxit Gold for cleaning and lubricating contacts and switches on old stereo gear and they are fantastic products.

Is there any reason not to use it for cleaning and sprucing up the contacts on computer gear as well?

Thinking specifically about places like cards and slots in motherboards, ribbon cables, etc.

And I would really welcome scientific observations by chemists and engineers in preference to guesswork (which I am quite capable of myself!).

Thanks!

They sell specific circuit board cleaners with no lubricant.

deoxit depending on the version has other stuff that may leave residue.

I sourced some relevant material for anyone that wants to elaborate. Is DeoxIT® DN5 Aggressive to Plastic?

Though wading through the website to find concrete data (like datasheets) is a bit of a pita.  Does it smell better than WD-40?

WD-40 smells the best. Petrol smells even better sniff sniff.

From the datasheet I linked...

DeoxIT D Series:
Petroleum Naptha 40-70% (dangerous if inhaled)
Difluorethane: 10-30% (intoxicant/dangerous if inhaled)
DEOXIT® D-SERIES, D100L: 3-7%

From this datasheet (MSDS link)

WD-40 Multi-Use:
Aliphatic Hyrdocarbon: 50-70% (dangerous if inhaled)
Petroleum Based Oil: 30-35% (intoxicant/dangerous if inhaled)
Carbon Dioxide: 2-3%

I feel that I asked a valid question.  I try to keep my playful side in off topic where it should be.

Tp4 prefers the smell of wood glue..  Never sniff it intentionally,  But whenever gotta do some wood gluing,  Much enjoy.

Are you a QNX user?

QNX is a Unix-like operating system, although not Posix-compliant IIRC (might have changed since I last used it).

It has a task query command: tsk

One of the options is 'tsk', although this option is not described in the documentation.

The command "tsk tsk" would produce the output "Have I been a bad computer?"

Perhaps they have changed it and removed that option and/or message over the years.  Companies don't have much sense of humour for things like that any more.

Damn it rowdy!  Why do you have to come along and mention QNX?! 

I just started a downward spiral of Debain ISO live-builds with the intention of eventually poking at busybox and you have to mention QNX.. 

First I learned of Danger OS.. now this.  Damnit.. :-[

Sincerest apologies - most of this should have gone into "off topic" a while ago.

As a non-professional upstart I use 99% isopropyl alcohol and something that leaves few particulates behind like basic coffee filters.

I guess oils could help alleviate static buildup during the less humid months, though I usually avoid anything that accelerates dust & hair buildup.

I would prefer 99% ethanol, had much better experiences with them compared with IPA... for example when using IPA for cleaning flux, it would leave behind a messy sticky residue

India Pale Ale for cleaning flux?!  Joking, I'd be a bit worried about a sticky residue from grain alcohol but honestly whatever gets the job done right?  My IPA evaporates for CPU/GPU clean-up jobs fast enough for to get the job done in a timely manner.  Coffee filter powers through even extra gummy thermal pastes like Tuniq TX-4.  Also used IPA to clean flux with aid from a used toothbrush and a coffee filter.  Even used tacky old flux--cleaned up well enough for quick solder bodges so idk.
