The safe serves more than a single purpose of just gun storage. I don't mind the odor so much, but the wife does. It is also a matter of controlling residue and vapors so as not to negate the fire protection of the safe (speak to your local fire department). Look at the MSD of the various oil and grease products with flash point and auto-ignition properties, let alone the smoke damage from inside the safe. A house fire can also cause the humidifier inside the safe to short out adding to a potential fire source. The smell of gun oil on a gun is ok, the smell of oil on a keep sake...not so much.... I use clp, air compressor and wipe off to clean the poly areas but sometimes I miss a crevasse and gravity does what gravity does over a period of time and hence the residue or a drip and vapor. Granted it's not the Exxon Valdez, but the material in the pocket holders are absorbent and they will eventually take on a new scent of their own thusly adding to the combustion concerns over time. When minutes can matter in a fire, I want to be prudent rather than cavalier in protection of the various items (business, heirlooms, etc) that were placed in the safe. The plastic baggies work great for odor/drip until I can obtain some materials from the comments that were left. That VCI stuff looks interesting.
