Barrel Cleaning copper solvent

Thats a great test kombayotch, you certainly put some effort into that test and we all can benefit.

I wonder if anyone who is planning to have a table at the Calgary Gun Show would bring in a larger order of the KG-12 and save on shipping.

Just a though, I would certainly give it a try.
 
I found something really interesting with their carbon remover (KG-1) too. I noticed while cleaning with it that blue appears on the patch at about the same rate as butches bore shine. When I get back from vacation, I'm going to run the test and see it it does anything to copper. My feeling is that is has a mild effect similar to the weaker products I tested.
 
Bore cleaning

I have been using Cr-10 and find it works wall for day to day use.
I also just finished cleaning a 6mm that had been neglected it was in bad shape at 100yrd it wood hardly stay printing on paper CR-10 wood not cut it !
the best thing was Bore Scrubber. Foaming Gel Bore Cleaner.
 
When I was playing with smooth like sidewalk surplus rifles, I used CR10 to 'mine' the copper. Works great and I still consider this the best commercial solvent for heavy work.

I have since moved on to something far more economical that also works, arguably, better.

Janitorial Ammonia Solvent. This is as concentrated as you can get without a license. USE OUTDOORS ONLY. EVEN VENTILATION IN A ROOM IS NOT ENOUGH.

Wipe it in, wipe out the copper. No waiting, no mucking about, just gets the job done FAST. I got mine at ZEP supply.

The time it takes to change a patch is all that it needs to sit. DIRT cheap at around $20 a gallon which will give you and a bunch of your friends enough solvent to clean for a decade. You use very little as it is so effective.

You never let it sit or dry so any fears of damage to steel is unwarranted (I have never seen ammonia damage steel either and I have tried). You will need a bit of oil after as it cleans to bare metal.

One surprising effect is that it can cut through some really cruded in powder fouling too.

I use it in my match barrels and I just don't see any powder caking in the throat. I have done autopsy on two 6.5's and there is simply no fouling in the throat area at all.

Of course, you can mix it with an oil or water to dilute. You end up with a strong commercial solvent :)

Another option is JB reg. or Borebrite. This will manually cut out the copper. Works very well.

Hi Jerry,

X2


In addition, I mix my Ed Red Bore Solvent and add some to it just before using in cleaning rifle. It is a little bit slower but protects bore at same time ( I want to believe)

I would love to find some amyl acetate ( banana oil) to make an ersatz of the Hoppe's No9 and its addictive smell. :)

KG-10 is one of the newer type of "cleaners" called chelating (ki-late-ing) agents. Because they are designed to be targeted to a specific metal, they can be very effective.

http://en.wikipedia.org/wiki/Chelation

Another chelating cleaner I have used is Evapo-Rust for removing rust. It, like KG-10, works like nothing else I have ever seen. MPro-7 is a similar type of product, but designed for broader types of cleaning.

The common problem using these cleaners is that they can tend to work slower than something like ammonia. You don't get the same "instant" results with the first patch. These cleaners require "soaking" time. An advantage over ammonia, is that these cleaners are basically non-toxic.

BTW, I tried Evapo-Rust on a cultivator tooth that had been outside for at least 50 years, soaked it for 2 days and was astounded that it removed ALL the rust, including out of pits that were 1/8" deep.

KG-12 works in exactly the same way but on copper instead of iron oxide, but as mentioned, requires soaking/wet time. I have also found that they seem to work faster if I clean the surface with MPro-7 first, to degrease and get other "debris" out of the way.

Komb: did you test any of the foams as well? I didn't see any in the links from earlier page.

No I didn't. However, several were tested in the report I referenced in the OP (on the Hide).

The editor of 6mmbr.com tested Wipeout foam. His results were similar to PatchOut.
 
kombayotch, I agree Kg have some great products. I recently did an in shop, on the bench test of various products, including sweets, KG, slip 2000 & several more. KG has a great line up for removing carbon, copper & a product for using when breaking in barrels. The added advantage is these products are not hazmat & so can be shipped easily whever you go hunting or competing.
A good point raised is when people look for the blue on their patch they are often using a brass jag????

Hello there,

Fairly simple question but I'm wondering if anyone knows of a good type of solvent to clean the caked on copper from a barrel that is overdue on a cleaning...Do these solvents harm the bluing? And what kind of process should be followed to do the job properly.

If anyone has some good professional suggestions I greatly appreciate it.

Good luck trying to find wipe out in Ontario, I've looked its nowhere to be had and ridiculous to ship
 
Hmmm...I got some of that KG12 a couple years back and it didn't seem to work worth a damn....I just cleaned with it, didn't try any fancy test.....maybe I'll dig it out and try again one of these days......?
