Gun Cleaner Test – Mil-Comm MC25 Gun Cleaner

I came up with a simple gun cleaner test. It’s composed of burning gun powder on a metal surface and then seeing how easy it is to clean with various gun cleaners..

I’m using a 6061-T6 aluminum alloy bar as the testing metal surface and H4831 smokeless powder. I’ll ignite about 50 grains of powder several times to create a good, hard powder fouling area. Then apply a gun cleaner, let it soak and then try to wipe it clean.

Let’s get started.

Here is the metal surface with the residue from about 50 grains of H4831 smokeless powder. The residue is pretty hard and cooked into the aluminum alloy. I tried to remove it with just a clean patch but No Way.

There is quite a bit of residue. It doesn’t burn clean unless under high pressure. But this is good for testing.

Now lets spray some Mil-Comm MC25 Gun Cleaner on the fouling and let it soak for 10 minutes.

I did not think it would wipe off so easily with Mil-Comm MC25. Wow…pretty amazing. The MC25 soaked into and underneath the burnt on fouling. It wiped off very easily.

Mil-Comm MC25 is an excellent gun cleaner but it is important to apply it generously and then let it soak. It lifts fouling off metal surfaces very well. It’s also non-toxic and does not have a strong smell. Here is a link if you want to try it….Mil-Comm MC25 Gun Cleaner at
