Before I start I just want to say that anyone thinking of doing this please keep in mind you are doing it at your own risk as this will void your warranty and potentially damage your keyboard.
So while I was waiting for my soldering iron to arrive from Aliexpress I wanted to lube my Mecha Mini that had brown switches on it. After watching a few videos of others spray lubing their keyboard and videos of what brown switches sound like lubed ,I decided to spray lube my keyboard.
After lubing the switches, i let it sit out to dry for a day and I have to say, I am kind of glad I spray lubed it as the keys feel so much smoother to type on. I believe it even fixed the chattering I was having before as well.
I had some serious pinging with the stock switches and with superlube it helped with that a bit but the most is the buttery feel of typing. I noticed that the tactility went down a bit but its not completely gone.
I am really impressed with spray lubing and cannot wait to try to lube it traditionally with krytox once my soldering iron arrives as I plan on swapping out these switches to Tealios.
Do I recommend you spray lubing? Well that is up to you but if you have a choice to solder, I would go the traditional route but just saying spray lubing works and is an option with the risk I stressed in the beginning.
Anyways I uploaded a video for sound comparison, sorry this is my first video so I have to work on my editing skills lol.
