I’m glad to see Hoppe’s has a non-flammable, biodegradable No 9 bore cleaner available….Hoppe’s No 9 Synthetic Blend Ultimate Bore Cleaner.
Let’s see if it works as well as the original Hoppe’s No 9 Bore Cleaner.
I’ll burn some smokeless powder on a metal bar and then see if Hoppe’s Ultimate Bore Cleaner can remove it easily…without brushing or scrubbing.
Let’s take a look at my gun cleaner test setup…
Here’s the Hoppe’s No 9 Synthetic Blend Ultimate Bore Cleaner. I wish it came in a bottle with a squirt tip instead of a wide mouth. Dipping bore brushes and patches into the bottle is not a best practice and you can’t pour with a wide mouth bottle without a mess.
This is my gun cleaner test setup…metal bar to simulate gun metal parts, H4831 Smokeless powder, lighter, cleaning patches and gun cleaner.
Hodgdon’s H4831 smokeless powder. It’s a slow burner so it’s pretty safe to experiment with in the open.
Here I’m cleaning the surface of the metal before the test. I wear nitrile gloves to protect my skin from the gun cleaner. Now i’ll add some powder to the metal bar.
Here’s the 1st powder charge. I’ll burn it and then add another charge and burn that. I burn 3 charges of powder in order to get a good build up and to get it to burn into the metal pores.
Here’s the first burn. I’ll skip to the final product to show you what the powder fouling looks like after 3 charges.
Here’s the mess. Now lets pour some Hoppe’s No 9 Synthetic Blend Ultimate Bore Cleaner and let it soak for 10 minutes.
I had to use a spoon to pour the cleaner onto the fouling. Pouring straight from the bottle would be too messy.
Here’s our fouling mess soaking. I’ll come back after 10 minutes and try to wipe it clean without scrubbing or brushing.
After 10 minutes, I used several clean patches and wiped across the fouling with very little pressure. Most of the fouling wiped off easily. The outside edges however did not but I think that was due to the fact that the outside edges did not get thoroughly soaked with cleaner.
The center section is spotless. Hoppe’s No 9 Synthetic Blend Ultimate Bore Cleaner is very effective and is non-flammable and biodegradable. It does not have a strong odor either.
