I use this white lithium grease to lubricate my 3D printer's lead screw and it works great! It's relatively odorless, easy to apply and if you get your hands on it, it's easy to wash off with warm water and dish soap. in bearings due to its high viscosity. It traps dirt and debris and essentially acts like liquid sandpaper, abrading rails and balls. I would highly recommend them if you are looking for a quality white lithium grease!
