Lubricating vintage tuners?

[u/BeenAway4tooLong]

Hey, folks. I’ve heard that vintage tuners of this type should be lubricated occasionally. I’ve heard Triflow is good. Just wanna check before I muck anything up.
So you just put a drop of lubricant in the holes in the middle of each tuner?
I assume you probably wanna loosen up the strings, put the lubricant in and then re-tighten the strings so the lubricant can work around a bit.
For reference, these are the original Kluson tuners on a 1967 SG Standard.
Any advice would be appreciated.
