Gun Cleaner Test – Otis Bio CLP

Otis Bio CLP is an excellent lubricant and protectant but how well does it clean powder fouling/residue?

Let’s conduct a test with some H4831 smokeless powder and a metal bar.

Here’s the equipment.

I’ll apply the Otis Bio CLP to the metal surface first, to see if it creates a barrier against the fouling. In theory, it should make the fouling easier to remove.

Now lets add some powder on top of the Bio CLP treated metal bar.

Here’s the H4831 powder charge ready to burn. I add a second charge afterwards and ignite it too.

Now let’s see what kind of fouling is left over.

Burnt on and bonded to the metal surface. Now lets try to wipe it clean without any additional CLP.

OK…it’s not wiping clean. Let’s try adding some BIO CLP on top of the fouling and then let it soak for 10 minutes.

After 10 minutes…it still not wiping clean. I rub the area briskly but it’s not coming off too easily.

Let me show you what a good gun cleaner will do.

Here’s the leftover mess. I apply some G96 Firearm Cleaner Degreaser to the area and wait 10 minutes.

Now that’s a gun cleaner…the fouling/residue wipes easily leaving a very clean and spotless surface.
