Just use the keyboard without touching it instead of wasting the whole thing.
One of the things that has spread since a long time ago, which self-proclaimed enthusiasts recommended to the newbies, is the 'spray lube'. Especially in the capacitive switch community, it's a bit cumbersome for beginners to build back to their original state with retaining the 'balance', so it's easy to try the way, and they're keep recommending wrong way to lube. Applying the lubricant between the slider and the slider housing? Oh it sounds much easier than to fully desolder a keyboard, pull out switches and lubricate. But I don't know how many people in the world have sensitive hands and are skilled enough to apply the same amount of liquid to equalize all the switches with the amount of lubrication. Maybe a master craftsman who has been making a Swiss watch for 30 years? And you think the beginner can successfully lubricate such ridiculous levels of difficulty? It's a method that they've never done before, don't know how much lubrication is needed. It's inevitable that each switch has a different amount of lubrication, so the auditory tactile feeling and the sensed pressure change all jagged. Someone who knows a thing or two won't even try.
Also, the risk of over-lubrication increases greatly, and the mechanism that over-lubrication occurs the most is whether the lube was sprayed too much in the first place or luckily some switches were lubricated satisfactorily, but the other switch was sprayed again because of scratchiness and noise. In case of over-lubrication, the mechanical switches will rattle with lube in the bottom housing, and in the case of capacitive switches, the lube will affect rubber dome, which, if worse, can invade the PCB. The ideal goal of lubrication is to create an even, smooth, unified sense of typing of all keys, and the ridiculous method of simplified lubrication completely goes against the purpose of this.
The expensive topre ones (realforce, hhkb, novatouch) are the most damaged keyboards by this simple lubrication, and a huge number of keyboards have been sacrificed for a very long time, probably still being tried, which isn't even mentioned in a real enthusiast community. "Spray lubing made my keyboard sound much better!" After reading these type of comments, still can't tell them not to do this because "I've already done it. None of your business". It's obvious that they're going to react like this, and a couple of replies will have no effect.
Anyway, there's no such thing as 'spray lube'. It's a way to send a keyboard to death, not to improve it. It may be a good idea to do it on a keyboard that'll be soon thrown away, but please don't, on a precious keyboard that you've decided to use for a long time. Oh, and don't even bother to do some stupid tricks that send the switch to the other world with contact conditioner or WD40. Even if you're an outsider, please have some common sense. Speaking about common sense, you're not worthy of a keyboard if you applied wet lubricant, saying "Oh, I can't hear the click. I guess that's why they said mx blues shouldn't be lubricated. Damn it."
TL;DR
1. Any kind of simplified lubing.
2. Don't do it.
3. I told you not to do it.
