We recommend that you use a proven corrosion inhibitor to protect your firearms during winter storage. We did extensive testing and recommend three products to combat rust: BoeShield T-9, Corrosion-X, and Eezox. These are all excellent products, but this Editor’s first choice is Eezox, because it cleans as well as protects, and because Eezox does not leave a sticky or waxy coating on your arms. Eezox is also ideal for fine, blued firearms. After 2-3 light applications it provides a dry protective finish that allows high polish blueing to shine through.

Eezox is available in small drip bottles, 4-oz. cans, and 4-, 6-, and 18-oz. aerosol spray cans. We typically apply Eezox to a patch from an aerosol can, then wipe down the firearm. Let the Eezox dry, then reapply. This will give you outstanding protection. Just make sure you wipe down ALL the metal surfaces, which may require removing the barreled action from the stock. We’ve seen examples of guns that rusted on the underside of the action because the owner had only bothered to wipe down the barrel and exposed section of the action. You can purchase Eezox from gun stores ($8.99 for 7 oz. can average price), or Warren Custom Outdoor.

Foam Cases Are Rust Magnets — Use Bore Stores
Just about the worst thing you can do in the winter (short of leaving your rifle outside in the rain) is to store firearms in tight, foam-padded cases. The foam in these cases actually collects and retains moisture from the air, acting as the perfect breeding ground for rust.

Those plastic-shelled cases with foam interiors are for transport, not for long-term storage. Don’t repeat the mistake of a wealthy gun collector I know. He stored four valuable Colt Single Action Army (SAA) revolvers in individual foam-padded plastic cases, and locked these away in his gun safe. A year later, every one of his precious SAAs had rusted, some badly.

For storing long guns in your safe, we strongly recommend Bore Stores. These synthetic fleece gun sacks are coated with silicone and corrosion inhibitors. The thick fleece also protects your guns from nicks and scratches. Rifle-size Bore Stores can be purchased for $13.00 – $18.00 from Brownell’s, or MidwayUSA, or direct from the manufacturer Big Spring Enterprises, which can also craft custom sizes on request.
