I’m looking to get a new keyboard since my current board (Cooler Master K653) is in rough shape, spilled some coffee on it a while back and it’s started to not register inputs randomly and sometimes doubletyping instead.

If you want a new keyboard, I don't mean to dissuade you, but if you're happy with the existing one and just don't like the post-coffee behavior, I expect that it's cleanable. I doubt that the issue you're seeing is from electrical damage.

I spilled an alcoholic beverage on my gaming keyboard and it still works, but they switches won't "unstick". I removed all the keys, soaked them/cleaned them, then wiped the keyboard down with alcohol/swabs pretty intensely but after drying they switches won't stop sticking. Basically just can't press without any resistance on a lot of keys and I'm not sure what else to do short of dumping alcohol all over it which, sadly, I'm unsure if will work/break/do anything since it just evaporates?

Any input would be great! Just don't want to replace a $150 keyboard and I'm sick of switching between my work and personal PC keyboard all day lol.

Soaking it in isopropyl alcohol would be my recommendation, but it sounds like you've tried that. If the switches were allowed enough time to absorb sticky residue you would probably have to disassemble the entire board and manually alcohol and lube each individual switch and each component within the switches.

The nuclear option, and iirc Linus tech tips tried this, would be to put the whole thing in the dishwasher and then dry it as thoroughly as possible.

Hey, just wanted to say thanks again - soaked in a vat of alcohol, rinsed, box of rice for 3 days - brand new. Cheers!

EDIT: It looks like 99.9% isopropyl alcohol goes for ~$25/gallon on Amazon:

EDIT2: Note that I grabbed low-water-content isopropyl, since my understanding is that 70% is normally used for disinfection because it's more-effective. If the goal of using isopropyl is to avoid having water, which might oxidize metal, dumped into something, I'd probably use low-water-content stuff. That being said, I don't have extensive experience in cleaning electronics, and I've also seen people recommending putting keyboards in water and having them be okay afterwords, as long as they are thoroughly dried first. I can't speak with any authority as to how much of a risk the water is. shrugs
