What is the recommended way to store an unopened container of lubricating grease?

Unopened lubricating grease containers should be stored indoors, out of direct sunlight, and in an upright position.  Drums, kegs, and pails should be covered, if possible, to prevent the accumulation of dust, dirt, water, etc. on the lid.  The lid should be blown off with compressed air (if available) and wiped free of contaminants before being removed.  Drums and kegs of grease should never be stored horizontally.  Smaller containers (cans or tubs) should be stored away from heat and out of direct sunlight.  Tubes of grease should be stored upright, with the removable cap at the top, away from heat or direct sunlight.
