I use lithium grease from a can. To apply it, I use a "Popsicle stick" applicator (or a 16d nail, or chunk of wood). That's been the method(s) I've used for decades. The used "stick" goes back in the can and the cover goes back on. The can sits on a shelf on a paper towel now (I used to use a chunk of cardboard). Basics.
