How to Get Rust Off a Gun?

Rust is the result of a chemical reaction between iron and oxygen. This is why many people believe that rust only happens when moisture, such as water or sweat from hands, gets on metal. However, this can happen in dry environments too! When there are particles in the environment like sand, saltwater (seawater), or dirt then those will also create a corrosive chemical reaction with the metal leading to corrosion which causes rusting. Rust isn’t just an aesthetic problem; it’s actually dangerous to have and is a safety concern because corrosion can weaken the metal, making it more prone to breaking or snapping.

Rust is not a pretty sight. The process of removing rust from a gun can be more difficult than you imagined. It can cause many problems with guns, such as malfunctions and general corrosion of the metal. If you own a gun then it’s important to know how to remove rust off your gun so that it will be in good condition for years to come!


How to Get Rust Off a Gun?

There are many different ways to remove rust off a gun, but the key is to find an easy and effective way for your specific situation. If you have never removed rust from a gun before, then this blog post will help provide insight on how to remove corrosion and make your gun look new again!

Simple Steps for Removing Rust from Guns

Start by thoroughly cleaning off all gun parts with soap and water. Try not to use steel wool as this will scratch up your firearm’s surface.

  • Use an aluminum foil ball dipped in vinegar to remove any excess rust left on the metal surfaces of your gun that was missed during step one of the process (be sure not to wet any moving parts).
  • Regular white toothpaste also works well if you don’t have some other form of chemical cleaner handy – just be sure to rub it into hard-topped areas like barrels, scope lenses, and the outside of the gun.
  • After cleaning, use a light coat of lubricant and wipe off any excess with an old rag or paper towel.

What Happens When a Gun Gets Rusty?

Rust is caused by two things: moisture and oxygen. When those two things come together, the oxidation process of rusting begins to happen on metal objects like guns. That’s why it’s important to store your gun in a dry place when not using it; that way you’ll be able to avoid this problem.

So, how does rust happen? Well, it all starts with a small hole in the metal. For example, say you’ve got your gun sitting on top of a wet surface for an extended period of time (think like weeks) and this is where the moisture from that surface seeps into your gun through its various crevices. The next step is when oxygen comes around to react with these minute holes we just talked about. Sunlight helps this process along by adding more energy to get rid of some of those pesky electrons!

How To Remove Rust off a Gun with Different Processes

The process of removing rust is an important one that should be completed with caution and care when handling any metal surfaces or machinery. It’s also possible that someone will come up with even better ideas in the future but there are some very good ones out there now too so enjoy this article on how to get rid of rust with different processes.

There are many different ways to remove rust off a gun, but I’m going to discuss some easy methods for removing corrosion from firearms below!

Remove the Oxidation:

The first method involves simply cleaning the gun with hot water and soap followed by wax or oil depending on what type of material the firearm is made out of. The second option would involve vinegar which can help dissolve some types of rust so make sure it’s your only choice if you’re dealing with metal corroding quickly due to oxidation. Finally, there’s always sandpaper as an option because grit will act like little scrubbers when rubbed against metal surfaces.

Battery Changer as Gun Rust Remover:

For a more hands-on approach, you can also use an old vehicle battery to remove rust from guns. Fill up the plastic container with water and add Epsom salts until it’s dissolved completely (this will make the solution less acidic). In addition, put your gun in there as well for about 30 minutes or so; if this doesn’t work then try scrubbing off the corrosion manually using steel wool and dish soap.

Lubrication plays a Key Role:

Lubrication plays a key role when it comes to preventing rust from forming. To be specific, oils are excellent because they help keep the metal surfaces free of moisture and other contaminants that would otherwise lead to corrosion.

Natural, Home Remedies to Remove Rust From a Gun

You can rust off your guns by using natural materials that are present in your home.

Baking Soda & Vinegar:

Mix baking soda and vinegar together in equal parts to remove rust from your gun. By using this method you can also clean up tough stains around your homes like blood or oil. This mixture has an abrasive quality to deal with more stubbornly adhered bits of dirt and grime; the soapiness helps break down any deposits left behind after wiping them away with paper towels.

Rubbing Alcohol:

Rubbing alcohol works well as a solvent. Alcohol is a solvent that’s great for general gun cleaning. Pour rubbing alcohol on the rusted area and scrub it off with steel wool. Rubbing alcohol will cut through rust, which is a type of oxidation, something that soaps cannot do.

Leather oil:

Apply a small amount of leather oil to the rusted area. Rub it in gently with your fingers, then wipe off any excess that doesn’t get absorbed into the metal itself. The goal is just enough to coat all surfaces evenly without dripping or soaking them through. Let this sit for about 15 minutes before wiping away and cleaning up any residue left behind by the dirt and grime that was removed.”

Lemon juice:

The acid in lemon juice will help to remove the rust. Squeeze some fresh lemon juice onto a cotton ball and rub it on the rusted area of the gun. Let this sit for about 15 minutes before wiping away any residue left behind by the dirt and grime that was removed.

Olive oil:

This is another good option if you want something different than leather or lemon juice. Apply olive oil generously to a cotton pad, then rub it gently over your rusty gun. Leave this to soak in for around 20-30 minutes before removing with a cloth or paper towel.

How to Prevent Your Gun from Rust

There are many different ways you can prevent your guns from getting rusty in the first place,

  •       Store it properly:

It is important to store guns in a cool, dry place. If this cannot be done because of the climate where the gun needs to stay then it should at least be stored in an air-tight container that will keep out moisture and other contaminants like dirt or dust.

  •       Use an anti-rust metal coating like Corrosion:

If you have a gun that is in constant use, it will be exposed to more moisture and the possibility of rust. One way to prevent this from happening is by equipping your guns with an anti-corrosion metal coating like Corrosion X products which are also good at removing existing corrosion.

  •       Apply oil:

Applying oil on your guns not only keeps it free from dirt but also helps protect against rust. This can be done regularly or just before storing away for long periods so there’s no need to worry about forgetting any part of the process!

  •       Keeps up maintenance:

Maintaining one’s firearm and keeping them clean goes a long way when preventing rust as well as restoring it. Remember to not only clean the exterior but also clean and lubricate the gun’s internal parts as well!

  •       Coat a Gun with Wax for Added Protection

You can add a coating of wax to your firearm as an added protection. This will help protect against the elements and also keep them looking good!

Wrap Guns in Plastic, Maintaining one’s firearms is not just about protecting from rust but is also a way to keep them clean for years to come. One suggestion would be to wrap your guns in plastic when storing or transporting so they are protected from moisture and dust which may lead to corrosion. Using anti-rust cloths, silicone-based grease on hinges, preservatives like WD 40®, gun oils, and other metal care products will all go a long way in preventing any type of oxidation that leads up to rusted surfaces over time. Be sure

  •      Keep Your Gun Out of Its Case to Prevent Rust:

Guns should never be stored in the original case that they came with. The inside of this case will trap moisture from your gun, which is a big reason for rusting and corrosion. Storage cases can also trap dirt or dust particles which are harmful to the metal surfaces of guns because they contain acids that will cause them to corrode more quickly.

  •       Replace Your Gun Oil With WD-40:

If you already have a favorite lubricant then you may want to try using just WD-40 before replacing all oils on your firearm with it. This way if there are any problems after switching over completely then you know what caused them without being left wondering why something went wrong when everything was going so well beforehand.

Spray WD-40 onto your clean cloth (or paper towel) until you have enough liquid on it for what you are going to do, then make sure that there’s no excess dripping off from any part of your hands into the barrel chamber.


A belt sander is not recommended because it will take off some of the protective coatings and can cause damage.

It depends on the severity of rust, but you should leave a gun in vinegar for about 20 to 30 minutes.

There are a few reasons why guns get rusty, but the most common is that metal rusts out due to exposure to air and water. This can be prevented by storing your gun in an area with minimal access to any moisture or oxygen when not in use.

 Metal corrosion is when the metal becomes a different chemical compound than what it was originally made of. This typically happens due to either prolonged contact with water or oxygen through an open wound in which these two things cause the metal to corrode and become a different chemical compound. To prevent this from happening, make sure that you are always storing your metal in airtight containers or sealed packages when not in use so as to keep it away from water and oxygen.


You have now learned some simple ways to remove rust from guns! Protecting your firearms is an important part of owning them as it can help prevent corrosion and damage when taking care of weapons, which may save the firearm in the long run. If there is severe rust on metal surfaces then it may be necessary to use other methods or professional services. Remember these few tips for gun care and safety next time you’re looking at investing in firearms for protection purposes!
