Gun Oil Friction Test – FireClean CLP

FireClean is another CLP or Cleaner, Lubricant and Protectant and it works really well. I first used it on my Zastava NPAP M70 AK-47 and did a review. It does clean and lubricate well. It’s also non-toxic and biodegradable. It doesn’t smell either. I like it!!

So how well does FireClean CLP lubricate? and Reduce friction?

I used a simple friction test to see how well gun oils reduce friction. I used an inclined plane made from 6061 T6 which measures 24″ long, 4″ wide and 1/2″ thick. It’s filed true and polished to 400 grit.

The 400 grit polish simulates the finish on most guns. anyway, you can read more about the friction test setup here.

FireClean CLP Friction Test

I first thoroughly cleaned the metal surfaces with M-Pro7 Gun Cleaner to remove any oils or contaminates. I then applied the FireClean per the instructions which are to apply and then wipe off the excess. I used patches to apply the FireClean and then to wipe off the excess. Ideally you want a ultra-thin film of FireClean on the metal surfaces.

I placed the sled on the inclined plane and raised it until the sled started to slide downward. I then read the Wixey digital angle gauge and noted the angle. I then lowered the plane and replaced the sled back at the top. I repeated this process 9 more times. I gathered a total of 10 sets of data and then averaged them.

FireClean CLP Friction Test Results

The average angle where the sled moved on the inclined plane was 10.77 degrees. Compare this with bare metal with 15 degrees and you can see that FireClean CLP reduced friction by about 31%. That’s excellent!
