I've responded to more than a couple questions on here about lubing keyboards and since I have my last endeavor documented I though I'd write up a picture guide on how to do it. I'm not doing it here but you can take this opportunity to do a spring swap if you want. Or even change the stem. You could go from a brown, to a red, to a blue switch, just by swapping the stem and spring. My switches here are Zealios, a special type of tactile Gateron switch similar to an MX Clear.
