I’ve cleaned the case itself in the sink and brushed the pcb with an old toothbrush (just had some dust on it). I’m probably gonna take it apart again and try to wash the pcb and the membrane with iso, hopefully that’ll help.
It now works pretty good after drenching the whole membrane/key switch layer sandwich in 99% iso a couple of times. The 7 key now works flawlessly, the space bar still occasionally gives me double spaces with one press but I’d say not as frequent any more, I’ll see if it goes away entirely as it dries completely.
Ayyy, result! I appreciate you getting back to me. It’s not perfect, but it sounds like at least the keyboard’s close to normal now. Time to pick a new spot to put your drink as well.
The iso shouldn’t have caused any issue, I’ve used it before for the exact same thing. It’s hard to say what the issue is at this point. It sounds like a loose connection or something bridging 2 connections. Could’ve scrubbed too hard, or maybe something got bent during assembly or disassembly. Sorry, man…
Didn’t scrub at all, though, literally just poured it in and swept it around a bit by tilting the whole thing…
Thinking about it, the num 0 always was a bit flaky, so it’s entirely possible the previous owner also did some damage. Makes me a little less sad about killing a 30 year old keyboard…
That’s what I thought as well but I’m always weary about IPA damaging the plastic… would it even evaporate properly between the layers?
I would fully take apart the keyboard. The plastic can be cleaned in the sink with dish soap and lukewarm water. The pcb gets the iso.

Good luck, lemme know if it worked!

Unfortunately it looks like I spoke too soon, I just tested it again and the inputs for the S and W keys are all over the place…
I really don’t know what’s going on, maybe I shouldn’t have used the full strength iso? Don’t really know what to do now.
