Some google searches suggest VCI emitters may yellow paper over time. So not a good idea for passports, etc.

The Google foo must be strong with you. I couldn't find anything about paper discoloration but just how they work.

I will just keep the plugged in rod and some dicassant bags in the safe and see how everything goes. If I decide to use a VCI emmitter, I think I will put documents in a sealed container to be on the safe side.

Thanks for the info.

Over an extended period of time, Zerust products will “yellow” paper so do not use them in the proximity to antique books, photographs, valuable documents, etc.

I have seen these and wondered do they leave a film on stocks, optics, or other sensitive items that might be inside?

WHY would they leave a film? They do not off gas any condensibles, they merely adsorb higher molecular weight components.

VCI emitters release a vapor that then is deposited on metal to prevent rust. I would be curious how that also effects wood, plastic, glass, and other items (passport, birth certificates, etc.) that are in the safe.

Our patented technology is non-toxic and safe to use on any weapon or firearm. Our products won’t leave a residue on metal or wood, and won’t harm stocks, grips, optics, ammunition or any metal finishes. Once an item is taken out of storage, the anti-rust molecules will simply dissipate into the air.
