How to rustproof a gun

This blog post will answer the question, “How to rustproof a gun?” and explain topics like important precautions to make guns rust-free, maintenance of guns, and frequently asked questions.

How to rustproof a gun?

Revolvers, guns, and shooters are all reliant on metal parts to operate normally, which makes them vulnerable to corrosion. The corrosion process can swiftly set in without secure storage, jeopardizing the gun’s safety and efficiency. 

Here are some important precautions to take when it comes to preventing gun rust.

  • Lessen the humidity level.
  • Keep out from the rain.
  • Cleanse your gun on a routine basis.
  • Make use of a good anti-corrosion spray.

Now I will elaborate on the guidance given above:

Lessen the humidity level:

  • Only a bit of water, including water vapor in the air, needs to establish contact with the gun to start the corrosion procedure. 
  • A humidity level of 50percent is excellent for secure storage. Any greater than this will cause corrosion, and any below would fracture timber gunstocks. 
  • To preserve this critical balance, use a dryer in the area where your weapons are housed, or keep a dehumidifier like silica in the gun case to absorb excess water.

Keep out from the rain:

  • Rainfall, snowfall, and other humidity create corrosion and patina rapidly, thus you should try to keep your rifle away from the downpours, snow, as well as other humidity. 
  • If it starts to rain while you’re outside, attempt to keep your rifle dry by putting it in a protected area. 
  • If it becomes wet, dry it properly and thoroughly cleanse it as rapidly as feasible.

Cleanse your gun on a routine basis:

Cleansing your gun is important for maintaining it in good working order since it removes any scorched gunpowder as well as other dirt that can retain humidity and cause rust.

Make use of a good anti-corrosion spray:

  • It’s a smart option to use a little coating of a strong corrosion preventative while wiping your gun. 
  • Solvent-based goods, those that involve livestock by-products, and those with heavy Toxicants should be avoided because they can harm your wooden gunstock and also have a bad smell that attracts bugs.

Here is a highly recommended anti-corrosion spray:


How and where to Keep Guns to Keep Them Rust-Free:

Proper storage is compulsory so that it operates accurately every time. 

This is how to keep your gun from rusting:

  • Place it in the Appropriate Case
  • Place it at the Appropriate Location

Place it in the Appropriate Case:

  • First and foremost, select the appropriate pistol case. The cover is the most important barrier against the intense corrosion caused by environmentally volatile chemicals such as water, filth, and salts. 
  • It’s critical to keep your gun in the proper handgun cover to keep those chemicals out. Pelican offers some of the best rust-proof pistol cases on the market. 

What kind of gun case is needed:

To preserve your pistol from damage, you need to have a cover that is foamy and hard, but it also needs to be waterproof and shockproof to keep corrosion-causing pollutants out of the air.

Here’s the best-recommended gun case:

Pelican 1170 Protector Case

Special features of Pelican gun case:

  • Moisture, dirt, and filth are kept out of Pelican gun bags owing to sophisticated pressure equalization valves. 
  • Additionally,  ring sealing gives additional protection against moisture entry.

Place it at the Appropriate Location:

  • While your weapon’s cover is a good first line of defense from corrosion, the environment inside which you keep it is also important. 
  • Of course, the main thing is to keep it somewhere that won’t speed up the corrosion process. 
  • Experts advise that you keep a constant eye on the temperature and relative humidity in the area wherever your case is kept.
  • You may buy an inexpensive humidity meter to keep a careful eye on the humidity level in the space. 
  • Given these circumstances, it’s critical to keep your guns out of any moist or soggy locations including the basement,  washroom, sheds, and campground.

Other Rust-Prevention Techniques:

While keeping your armory in the proper atmosphere is a vital first step in preventing rust, there are a few other considerations to keep in mind in order to reduce or stop the corrosion process entirely.

  • Maintain the cleanliness of your weapon.
  • Destructive ammunition should be avoided.
  • On a gloomy or stormy day, don’t bring your gun outside.

Maintain the cleanliness of your weapon:

  • Saline particles, as well as other small particles in the air, can build on metallic surfaces. 
  • Sand and dust particles can damage the metal, causing corrosion patches to form and shatter at the same moment. 
  • To avoid this, it’s a smart idea to wash your pistol on a regular basis.

Destructive ammunition should be avoided:

Potassium-chlorate primers in toxic ammo disintegrate to salt, and we all understand that salt is the finest thing to throw at metallic surfaces to make them corrode quickly. If you favor this type of ammunition, clean up your pistol well after each practice.

On a gloomy or stormy day, don’t bring your gun outside:

  • Use a foldable gun case if it’s really necessary, and only take your weapon when deemed needed. 
  • Take an absorbing towel with you and clean it off after each bullet to assure that your weapon is completely dry.

Different ways to protect your guns from rust:

  • Lube Your Firearm To Protect It From The Outdoor Components.
  • Dehumidifiers, silica, cosmoline, and sealed bags can all help.
  • Maintain your weapons on a routine basis.
  • If the weather is poor, don’t take your rifle out.

Lube Your Firearm To Protect It From The Outdoor Components:

Why grease should be used:

  • Grease, unlike oils, has a higher viscosity and usually stays in which it is applied. 
  • It won’t even run back to the bottom of the gun cabinet or get wiped away in the weather. 
  • Rust-Resistant Grease, or RIG as it’s also called, is a marvelous substance that enters metal parts and remains there to build a rusted shield. 

Grease should not be used in gun bores:

  • Although RIG’s instructions state that it is safe to be used in gun bores, I would advise against it. 
  • When a smear of hardened grease collides with the cloud of gases released by an exploded round, the temperatures in your barrels may rise to dangerous levels.

A highly recommended grease I have found:

White Lithium Grease

Dehumidifiers, silica, cosmoline, and sealed bags can all help:


  • A dehumidifier maintains optimal water content around your guns. 
  • The relative humidity in the NRA museum, which houses rare vintage firearms, is kept at 55 percent.

Silica Gel:

  • A silica weapon-safe dehumidifier is the best option.
  • The silica gel particles soak any wetness caught inside the gun. 
  • The gel particles must be replaced on a regular basis. 
  • Some types of silica gel can be regenerated by putting them in the heater for a few seconds.


  • Cosmoline is a sticky material that prevents corrosion in prolonged storage weapons. 
  • It appears like a viscous, packed sludge at ambient temperature. It turns very watery when warmed. 
  • Spraying your weapon in cosmoline will keep it rust-free for a long time. 
  • However, ensure that each and every droplet of cosmoline is wiped from every single corner of your gun before removing it from storage. 
  • This is a time-consuming procedure. is a sticky material that prevents corrosion in prolonged storage weapons.

If you reside in a humid area, pressure packing your handgun is an excellent technique to keep water vapor and air out. Because there is no oxygen present, there is a significantly smaller possibility of rust forming on your firearms.

Maintain your weapons on a routine basis:

Why maintenance is necessary:

  • On the base metal of the weapon, micro contaminants, dirt, salts, and liquid water can build. 
  • You’re putting your guns prone to corrosion if you don’t maintain them on a routine basis. 
  • The biochemical reaction that occurs when you fire your firearm draws a lot of particles from the surroundings into the gun. 
  • That is why it is critical to maintain and lubricate your rifle as per the assembly specifications on a frequent basis.
  • Since water and oil do not really interact, a coating of oil will keep humidity out of your gun’s parts.  
  • A gun that is rust-free is a dependable weapon.

If the weather is poor, don’t take your rifle out:

  • When it’s pouring or hailing, it’s more likely that your gun may rust. 
  • Of course, we can’t always choose the ideal conditions for shooting, sporting, or when we have no choice but to employ guns.
  • When transporting your guns into a damp, stormy, or snowy environment, always use transportable watertight gun bags and only carry your gun when strictly necessary.
  • If this isn’t an option, keep a very absorbing fabric handy to maintain your rifle as clean as possible. 
  • When you get home, remember to clean it thoroughly and keep it in a good gun bag.

Frequently Asked Questions(FAQs): How to rustproof a gun?

Will my gun rust in a gun case in my garage?

  • If your garage isn’t warm, you reside in a humid area, or you don’t even have a drier or dehydrator, it’s unlikely that your weapon will stay long. 
  • Cold metals, like a glass of chilled water, may absorb moisture from the surrounding. You’ll have corrosion protection issues on your hands if it collects within the weapon’s internal dynamics.

How do I remove rust from my gun?

Corrosion avoidance ought to be your top priority, but if you do come across corrosive elements, you can eliminate them with brillo pads and weapon oil. After you’ve checked that your weapon is empty, do the following:

  • Spray the rifle lubricant to the areas that are affected.
  • Allow the product to soak into the corrosion for a few minutes.
  • Clean the gun’s exterior using a piece of cloth.
  • Gently scrub the afflicted rust patches with brillo pads or a brass brush. 
  • If you use too much force, the weapon’s surface will be ruined.
  • Rep the procedure till you’re happy with the results.
  • It’s advisable to outsource the repair of your pistol to an expert if it’s badly corroded.

How soon after use should I clean my gun?

  • Cleaning the gun right once you get home from the practice isn’t essential. 
  • However, to prevent rusting, it is critical to cleanse weapons after a few days of usage. 
  • The type of firearm, its vintage, the type of ammunition used, and other factors all have a role in how much you repair your pistol.
  • Corrosion can develop on fingerprints from gently rubbing a rifle and not cleaning it off. 
  • That’s why, when maintaining and repairing guns, it’s not uncommon to use plastic gloves to preserve them – and to avoid other poisons from entering the skin.

Is it possible for my gun safe to be too dry?


  • When your weapon is moved between extremes of temperature and moisture, such as from hot weather to cold conditions or from severe desiccation to humid conditions, the wooden, steel, and polymer parts will expand and contract rapidly.
  • The recommended moisture level for the gun cabinet is 40 percent to 60 percent humidity, with a constancy of 50 percent ideally.
