Logitech G512 and strange cleaning issue.

So, after about a couple of years of use, this keyboard started to have issues with keys not working right. Double clicks or clicks that only occured after mashing the button repeadetly etc. Only happens to the same keys, which is basically the entire top row from F1 to Pause, the entire numpad and the lowest row from ctrl to ctrl (barring the space bar which i was somehow able to fix permantently through sheer violence).

I've tried cleaning the keyboard several times, with last time literally bathing the switches in rubbing alcohol. This fixed the problem, but only for a short while, until it started again. I futively (or so i thought) blew over the affected keys with my mouth without even removing the caps, just venting frustration while i considered dissassembling the whole thing in my head, and low and behold, the keys work after that, but only for a few minutes.

Not sure what is going on here. Can it be that within minutes dust somehow settles inside the effected switches? Why would blowing over the key without even removing the caps work, and why can't i achieve permanent cleaning after literally drowning the switches in liquid, if all it takes to make them work (if even temporarily) is a bit of air? This is driving me nuts every time i need to use the affected keys now i have to blow over them my family is even starting to make fun of me as they hear me doing it inside my own room.
I checked a video on how to take the thing apart and it seems the PCB is right under the top metal plate, so i'm not sure i can even reach the contacts better that way:

I'm assuming taking the PCB off the plate would mean ripping the switches apart. I could just let isopropyl alcohol drip down from the side of the PCB. Can't think of anything else i could do.
 
I had the same thing happen with my previous corsair keyboard, and tried the same things. Air, IA, contact cleaner, deoxit, they all got it working for a short period of time then the keys stopped working again. Mine was more of a problem as it was WASD keys that had the issues, so it made it extemely annoying to play games. I wasnt going to take the whole thing apart and solder in new keycaps, so I just ended up buying a new keyboard.
 
The strangest thing is that just blowing at the key makes it work every single time, just not for long. And like i said don't even need to remove the cap. I just can't understand the mechanic of it.

Also, if dirt is the issue, why is it those only keys are affected? The entire middle part of the keyboard comprising all the letters works flawlessly and yet that was the area with the most dirt. Like, around the WASD area i had a film of packed dust that was so thick it peeled off in its entirety when i pulled it out. Meanwhile there wasn't really that much dirt around any of the affected keys.

The first time this started happening i assumed the switches had become faulty somehow but if blowing air at them makes them work that can't be an hardware issue, can it? And yet, if it's just dirt how is it that it just can't be removed, and why is it that only those keys are affected and never any of the others.

I don't have the money to get a new keyboard right now. When i do, i'll definitely take this one apart and throw the whole plate with the switches into a bucket of alcohol if i have to.
 
So i literally drenched the keys in alcohol lol. Didn't even bother with cue tips. I just used rolled strips of toilet paper, fully drenched in alcohol to the point a pool formed under the keyboard after i tilted it. I spend quite a bit pressing and jiggling keys around, flicking them with my finger, banging the keyboard sideways and upside down etc.

Just turned the computer on after a few hours to make sure everything dried up and so far it's actually working. We'll see if this holds, if it doesn't i'll take out the plate with the PCB and the switches and just pour alcohol into the damn thing straight up from the bottle. If even that doesn't work i'll just torch the damn thing and get a new one.
