What to Look for in a Gun Cleaning Oil?

A gun cleaning oil is a must-have in order to have a functioning oil under all circumstances. This is because a gun is made of metal, and metal is very much prone to rust.

On top of this, when different parts of metal friction against each other, the chances of corrosion rise high. Therefore, you must purchase a good quality oil to protect your firearms. The factors to look for in a good quality gun oil are:

Ability to Withstand Tough Weather

Oils that have a high viscosity have the tendency to harden in cold temperatures. That can be very troublesome if you live in a cold place, or you need to use the oil on your gun in cold weather. Therefore, make sure to purchase an oil that won’t harden under any circumstances and come to your use when needed.

Viscosity of the Oil

How viscous your oil is will depend on the amount of grease added to it. Usually, to make lubricants and gun cleaning oils, grease is mixed with a type of soap-like base that helps it to achieve the perfect consistency needed to protect metal surfaces.

Depending on the amount of grease added to the oil, it can either be thin or thick. This can be understood from the NLGI number mentioned on the packaging of the oil. The higher this number, the greater is the thickness of the oil and vice versa.

Formulation of the Oil

The formula of the oil is very important, which determines the end-result it will provide. For example, various kinds of tiny solid particles are added to the oil in order to make it work against rust, corrosion, extreme weather conditions, and so on. The most common types of such additives are mentioned below:

  • Zinc
  • Detergents
  • Boron
  • Antimony dialkyl dithiocarbamate
  • Phosphors etc.

How to Clean a Gun Properly?

Down below are a few things that you really need to know about before cleaning your gun. Without further due let’s get to them.

Unload Your Gun

The first and foremost thing that you need to do before cleaning your gun is to unload it to prevent any kind of unwanted accidents.

Prepare a Brush

Next, you need to prepare a brush that you can use to apply the lubricant on parts that face frequent friction.


Make sure that the oil is viscous enough to stick on those crevices and does not fall off once you apply it.


Use the applicator of the product or a brush to apply the product to the desired area evenly. On parts that are dirty, apply the oil thoroughly, and let it rest for some time. Then use a wiper or a piece of cloth to wipe off the oil along with the dirt.

Is Ballistic Oil Good for Cleaning Guns?

You must be wondering what a ballistic oil is. Well, it is none other than the Ballistol oil that we have mentioned as the 3rd pick on our list. It is named so because it is a combination of the two words ballistic and the Latin name for oil.

This product is a very good agent for cleaning oils because of its ability to migrate to tough parts. Moreover, the oil can be applied just like an aerosol. Therefore, there is no risk of creating a mess. So, you can use this oil without having second thoughts to clean your gun.

Will Gun Oil Remove Rust?

Although it is said that prevention is better than cure, gun cleaning oil can provide both. It can not only prevent rust but can also remove it once it is formed. Gun oil is formulated in such a way that it acts as a barrier against the moisture of the air.

As a result, the metal surface does not come in contact with oxygen and the water vapor of the atmosphere, which prevents rust from forming. In addition, it also contains materials that react with the rust and helps to remove it once it is formed.

Apply the oil on the rusted surface, wait for some time and then wipe it off. You can have a gun completely as good as new.

How to Make Gun Cleaning Oil at Home?

Formulating a gun oil at home can be a difficult task if you are not an expert. This is because some of the materials that are added here can prove to be hazardous for you and your health if not used with proper care.

The three main ingredients to use to make gun oil at home are two parts of Mobil, 1 part of Dexron transmission fluid, and 1 part of STP treatment oil.

However, we highly recommend purchasing a readymade one instead, as trying to prepare an oil at home can pose a great risk to yourself and those around you due to the addition of some hazardous materials.

Frequently Asked Questions

1. How much gun oil should I apply?

It completely depends on the amount of rusting or corrosion on your gun. Usually, applying a little on the affected area is more than enough to do the job.

2. Should I purchase an expensive gun oil?

A price tag does not always guarantee quality. Therefore, as long as a product has good reviews and is affordably priced, you should purchase it.

3. Why are detergents added to gun oils?

Detergents are added to provide gun oil with cleaning properties.

4. Should I purchase a thin oil or a thick one?

Oil that is too thin will spill, and if too thick, it will build upon the metal surface. Therefore, purchase the one that adheres to the metal perfectly and can be wiped off easily without forming any sort of build-up.

5. How does gun oil prevent corrosions?

When metal parts rub against each other roughly, their surface wears off. A lubricant moistens those rough parts and thus prevents hard collisions, which eventually puts a restriction on corrosions.


Just owning a firearm does not guarantee your safety if you do not maintain it properly. And in order to ensure the proper functioning of a gun, using a gun oil regularly is a must. Therefore, follow this guide for the five best gun cleaning oil properly, and you won’t be disappointed.
