How do you "liquidate" a dried tip of a silver pen? I got one that's
unusable.

Look up the MSDS for the product.

You meant I should have just thrown it away properly?

Ohhh, I did not know about this. Found a "pen" of conductive paint,
ironically from MG Chemicals (the 100% Alcohol is from them.) Darn, I
have already removed a bunch of parts from the keyboard; guess I'll
have to put it all back together now.

Excellent suggestion, thanks! I will try this in maybe 2 weeks? Will
come back and let you know if it works.

The problem is the membrane sits between the metal backplane and the
black plastic base which holds the keys. The two (metal backplane and
black plastic base) are held together by melting the black plastic
rivet-like - I cannot separate them...

Have a chat with them, see what they've got.


They have seen this thread, I am pretty sure, and are probably not
happy; they are not chatting with me anymore. But for a hundred bucks, I
expected a working USB controller; there were different bugs on two of
the controller versions I had. I expect bugs from some things, but not
from a Model M keyboard.

I got the same thing over @ TeraBytes Unlimited. I complained that their
multi-boot tool was erasing my partition tables each time I rebooted the
computer. I made a very detailed bug report and got the standard Service
Desk "It must be you, just reboot" kinda response. After 2 responses
like this I got mad, explained I was not some 10 year old kid and that
they read the bug report I made explaining exactly how to reproduce.
They fixed the bug like 2 days later, but to this day, no matter my
pleas, the support person will not talk to me anymore. They are
childish; I do not recommend them anymore.

Best Regards,

For some chemical compounds, they're simply solvated.
And when the solvent evaporates, you add some more
solvent and that "rejuvenates" the material and allows
you to use it.

However, if an irreversible chemical reaction happens,
you can pour all the ethanol you want on it, and it
won't be good as new.


Thanks. Irreversible chemical reaction ....

I have a membrane keyboard (now retired) and the membranes
are welded to each other, but not to anything else. They fit
over alignment pegs, and that's what keeps the membrane aligned
with the key array.

It made it very easy to clean. After a coffee spill, just pull
the membrane pile and rinse in cold water for a while. The membranes
can be held apart while it dries, then reassemble.

How I ruined that, is removing the keycaps and cleaning underneath.
That seemed to be too much for the thing. So on my keyboard
(not the same brand as yours), the keyboard treated me really
well.

Now, if you take the $150 boat-anchor Apple keyboard, that
one when I spilled coffee on it, the thing was riveted
together, and an attempt to drill a rivet, just made it
spin around. I rinsed that for a long time, dried it for
a couple days in a gently heated airstream... and still three
keys were sticky enough to not work properly. $150.00 out
the window...

I'll have a look at it again, maybe I can pull it out without separating
the keyboard and the backplane - there must be a trick, if UniComp sells
the membrane separately. I would ask them what the tick is, but since
they're not really talking to me anymore... They did send me a foam pad,
free of charge, when I told them about my problem (or when they saw my
post here,) so they still want to do the right thing; I'm pretty happy
with the service I got from them.

See, using water on a keyboard is possible, lol, but make sure to dry
those blucking springs properly, or they will rust! ;-)
