I have a half-dozen zerks on my pick-up truck that, given its low annual use, need a couple of squeezes of grease once a year, and another couple on my in-laws' riding mower that I use and maintain. Otherwise, my pistol-grip grease gun hangs on a nail in the garage, waiting for its brief annual uses. Between uses, though, it drizzles a slow (or in hot weather, not-so-slow) expanding puddle of red solvent/carrier---kind of a continual mess. What am I doing wrong in how I'm using and storing the grease gun, or is my only recourse to put it in some kind of container to leak as it will, and clean it up when the time returns to dab those zerks?
