Gun Cleaner Test – Archoil AR4200 CLP

Archoil AR4200 is an excellent lubricant and protectant but how well does it clean?

Let’s put it to a test.

Let’s see how well it prevents and removes burnt on smokeless powder residue.

I’ll treat the metal bar with AR4200 before I burn the powder to see if it stops the powder ┬áresidue from sticking.

I was able to remove the fouling/residue with just a clean patch. It was not easy and took some force but AR4200 does provide a barrier against the fouling. Now lets add some Archoil on top and see if it removes it easily.

I applied a liberal amount of AR4200 and then let it soak for 10 minutes. It did not loosen the fouling very much. It was difficult to remove. You can see 2 areas that will not wipe clean and might need a brush.

Conclusion: Archoil AR4200 CLP is a very good lubricant and protectant but not very effective as a gun cleaner.
