Most effective way of cleaning a mechanical keyboard, behind the switches under the keys?

post #1 of 8
Thread Starter 
Ordered a Corsair k90 on Amazon which was listed as very good condition that had a few keys that would stick. Took a eye dropper and toothpick to try to clean underneath each key, but some keys would sop working until I'd use my electric duster to blow away any extra liquid. I've been battling withthe keyboard for a few hours now, having the same few keys be stuck held down or pushed with other keys that aren't even near that key.

So simple and effective, thanks. The 3 and 6 keys on the numrow only work for a few seconds after plugging back in. Is there still residue somewhere causing a disruption?

Have you checked all the soldering on the board?

Not sure I could tell if the soldering is bad. I'm pretty sure it's fine because nothing looks wrong with the little metal bits on the board, and the numbers all worked before i tried cleaning them with the wet toothpick.

How about the switches themselves? I know you can change them by removing current ones and soldering new switches. It might be some defective switches, such as someone spilled beer on them.
