Right now my Leatherman is soaking in vinegar because roommate borrowed it and did not clean it. Needless to say, it grew rust.
I'm not really the best on maintenance, so I'll ask. How do you keep your tools in usable shape? I learned recently not to use blades to clean things, as it scars and naffs up the thing you are trying to clean.
Thankfully I had quite a few T-shirts ready to die, so I cut them up into strips. I've been using them to wipe things down, and that works better than scraping poo out with my pocket knife.
