Rifle barrel cleaning solvents – the type which smell of nitro benzene – are designed to remove metallic fouling from the rifling.

This is usually gilding metal, which is a high-copper brass.

They do this by attacking the copper, and reducing it to a green salt.

They will also safely remove plastic and lead from shotgun barrels, although you don’t usually need anything quite as powerful for this task.

At risk of giving a free plug, I usually use Napier shotgun barrel cleaners, although there are plenty of other good ones out there.

One sort of cleaner I do avoid is the type based on soluble oil, which is meant to be used dissolved in water.

To me, water means a risk of rust unless the stuff is used very carefully.

If you do have to resort to rifle barrel cleaners, remember that your bronze brush has a high copper content, and the solvent will attack the brush unless it is washed out immediately after use.

And yes, I’ve done it – reduced a 12-bore brush to a 20-bore in a matter of days!

    May I encourage you to try Clenzoil?

    Free samples are available to anyone.

    Whats really important to understand is the Foaming Aerosol contains
    ‘No CO2’
    ‘No Compressed Air’
    ‘No Butane, Heptane or Propane
    and is engineered with Medical Grade Nitrogen
    It disperses any water present and absolutely prevents rust so understanding this allows you to understand that other CLPs that contain CO2 are introducing water into their firearms and using propane ect is highly flammable which is a concern when dealing with firearms.

    Clenzoil will find that getting a person to try its products for the first time is difficult but for anyone looking for bad press on it will struggle as its clients are the US Military for extreme heat and extreme cold conditions and Navy Seals Museums who collect fine antique weapons and don’t trust anything else.

    A free sample??? Go grab one! ‘Simples’
