What is the best rust preventative for guns? - Arms Preservation Inc

Fail-Safe Gun Rust Prevention:

If you want reliable, repeatable rust prevention—without messy greases—pair Breakthrough Clean Technologies®(BCT) gun-care products with Arms Preservation Inc. (API) VCI Firearm Storage Bags. This simple combo cleans, lightly lubricates, and then surrounds your firearm with protective VCI (Vapor Corrosion Inhibitor) molecules inside a rugged, reusable, Made-in-USA storage bag. It’s a proven workflow for short-term or long-term gun storage—trusted by hunters, competitive shooters, law-enforcement personnel, and military armorers.

Why pair cleaning with VCI?

  • Cleaning removes corrosive residues. Carbon, salts, and fingerprints kick-start corrosion. Proper solvent + wipe-down = clean baseline.

  • Light oil adds boundary protection. A thin, even film reduces metal-to-air contact.

  • VCI completes the seal. Inside API’s multi-layer VCI bag, safe vapor molecules bond to metal surfaces, forming an invisible barrier that keeps out moisture-driven rust—no dripping oils required.

Result: clean metal + light lube + VCI atmosphere = fail-safe rust prevention for safes, field lockers, squads cars, and armories.

What you’ll use (all available from API)

A simple, repeatable storage routine

For short-term storage (days to a few weeks)

  1. Unload & clear. Safety first.

  2. Clean bore and critical contact surfaces with Military-Grade Solvent; wipe dry.

  3. Apply a light film of High-Purity Oil to exterior metal (barrel, slide, receivers, controls). Avoid over-oiling; a thin, even coat is best.

  4. Wipe hands & touched metal with Lead & Heavy Metal Removal Wipes to remove salts and residues.

  5. Bag it: Place the firearm in an API VCI Firearm Storage Bag. Smooth the bag flat and close the Velcro fully to trap the VCI environment.

  6. Store in a stable, low temperature swing environments

For long-term storage (months to years)

  1. Deep clean with Military-Grade Solvent; dry all solvent residue.

  2. Very light protective oil film with High-Purity Oil—think “micro-sheen,” not “wet.”

  3. Optional: Place compatible accessories (magazines, optics mounts) in their own small VCI pouches or within the same API bag.

  4. Glove up & final wipe: Use Lead & Heavy Metal Removal Wipes on any touched surfaces to remove fingerprints.

  5. Seal in API VCI Bag: Close the Velcro completely. VCI molecules are drawn to  and protect all interior/exterior metal surfaces.

  6. Label & date the bag’s exterior for audit trails (ideal for armories).

Tip: VCI protection is additive to a clean, lightly oiled firearm. Heavy, dripping oil isn’t necessary—and can attract dust and imprint foam. Keep it light.

Who benefits—and how

Hunters

  • Rain, mud, and temperature swings are no match for clean + VCI.

  • Off-season storage is simplified: de-scented, clean, and rust-free until opening day.

Competitive shooters

  • High round counts create fouling and salt. Quick solvent + light oil + VCI keeps match guns consistent between stages and during travel.

  • VCI bags help maintain zeroed optics by preventing mount corrosion.

Law-enforcement personnel

  • Patrol rifles and shotguns face daily carry humidity and vehicle temp cycles.

  • The clean-oil-VCI workflow reduces downtime, standardizes maintenance, and helps avoid surface rust that can slow inspections or qualifications.

Military armorers

  • Ideal for rack-stored weapons, deployment prep, and long-term warehousing.

  • Label-and-seal with API’s rugged, reusable VCI bags to support accountability, corrosion control programs, and periodic inspections without heavy greases.

Why “Made in the USA” matters

  • Quality & consistency: BCT fluids and API multi-layer VCI bags are produced to tight, repeatable specs for predictable protection.

  • Supply assurance: Faster replenishment and support.

  • Support domestic jobs: Both brands are proudly Made in the USA.

Frequently asked questions

Will VCI interfere with my oil or finishes?
No—VCI molecules form a temporary, invisible barrier on metal and do not attack finishes. They complement a thin oil film. Remove VCI by simply airing out or wiping down before use.

Can I store optics inside the VCI bag?
Yes—API bags protect metal housings and fasteners. Keep glass caps on and avoid pressing the optic against abrasive objects.

How long does protection last?
With proper prep and a full Velcro seal, API VCI bags are designed for multi-year (5-10 years) protection. Inspect on your normal maintenance schedule.

Do I still need to clean before shooting?
A quick safety check and function check is recommended. If desired, run a dry patch through the bore to remove any oil film before live fire.
