Frequently asked questions

Is Ballistol GunEx suitable for cleaning a barrel?

Yes. GunEx helps remove normal powder, soot and tombac residue and is suitable for routine barrel cleaning. A heavily copper- or tombac-fouled barrel may require a dedicated bore cleaner such as Ballistol Robla Solo MIL.

Can GunEx be used for long-term firearm storage?

Yes. GunEx is designed to protect bare metal components against corrosion during long-term storage, including in damp and changing conditions. Clean and dry the firearm before applying a thin, even layer to its metal surfaces.

Can the oil remain inside the barrel before firing?

No. Wipe the barrel and chamber with dry patches before loading or firing the firearm. Visible oil and loosened deposits must be removed, as excess oil can interfere with normal operation and may cause undesirable pressure effects.

How does it differ from the 200 ml GunEx MIL CLP spray?

The 400 ml GunEx is the classic gun and corrosion-protection oil with a mineral-oil-like odour and a manufacturer-specified operating range of –50 to +100 °C. GunEx MIL CLP has a newer fully synthetic, solvent-free and odourless formulation, an operating range of –56 to +150 °C and separately listed military-performance requirements. The larger classic GunEx aerosol is a practical option for routine maintenance and higher-volume use.

Can GunEx be used on fishing equipment?

Yes. The manufacturer lists fishing rods, telescopic components and metal sliding mechanisms among its possible applications. Avoid applying it to fishing line, handles or reel drag components unless their material compatibility has been confirmed.

Is GunEx suitable for wood, leather and optical surfaces?

GunEx is primarily intended for metal surfaces. Use a material-specific care product on firearm stocks, leather, rubber, plastic and optical surfaces. If material compatibility is uncertain, test the oil on a small concealed area first.

How should GunEx be applied?

Confirm that the firearm is unloaded and the chamber is empty. Shake the aerosol and apply a small amount to a cloth, brush or cleaning patch. Clean the required surfaces, remove loosened deposits and leave only a thin protective film on the metal. Avoid saturating the mechanism with oil.

How should the aerosol be stored safely?

Keep it away from children, heat and direct sunlight. Do not damage or burn the pressurised container. Avoid swallowing the oil, inhaling the aerosol and releasing the product into the environment. Dispose of the contents and container according to local regulations.

When is Ballistol GunEx 400 ml the right choice?

GunEx 400 ml is well suited to users who maintain firearms regularly and need a larger supply than the smaller aerosol sizes provide. It is a practical choice for routine barrel cleaning, lubrication of moving metal components and protection against moisture, salt-laden air and corrosion during storage.

A dedicated copper remover is more effective for intensive cleaning of a heavily fouled barrel. Grease may remain in place longer on heavily loaded sliding surfaces. GunEx is particularly useful as a general-purpose firearm oil with good penetrating properties and long-term corrosion protection.

Expert recommendation

Before maintenance, always confirm that the firearm is unloaded, the magazine has been removed and the chamber is empty. Keep live ammunition away from the working area. Apply GunEx to a cloth, brush or cleaning patch instead of flooding the mechanism directly. This provides better control and helps prevent oil from reaching optics, stock finishes or components that should remain dry.

Clean the barrel and surfaces carrying combustion residue first. Then apply a very thin film to moving metal components. A firearm exposed to rain or salt water should be dried before oiling. Leave an even protective coating for long-term storage, but wipe the bore and chamber dry before the firearm is used again. Excess oil attracts dust and may impair the operation of a mechanism in cold conditions.

Long-term protection for firearms and metal mechanisms

Ballistol GunEx removes normal firing residue, keeps moving metal components operating smoothly and protects firearms against moisture and corrosion. Its creeping properties, silicone-free formulation and large 400 ml aerosol make it a practical choice for regular firearm maintenance.
