Hi guys, this morning I noticed that my ALT key has a little resonating spring, so I think he need some oil.
I read some topic, old and new...and each man says his opinion, so I`m a little confused. I dont want ruin my leop

I never lube my last Mx cherry and I just saw some video on youtube like this:
But I cant disassemble my keyboard (just for ALT)...so can I lubricate in another way?
And do u have some tips for the oil?
Thank a lot
