Wipe-Out is fantastic.

Don't accept any of the foam imitators, Wipe-Out is what you want.

I have to shoot full copper for my hunting hand loads so I'm intimate with copper fouling. Use Sweets 7.62 Solvent.

Hoppe's Benchrest has served me well for years.

KG-12 is by and large the best out there. It removes more copper than all of the rest, without any of the problems like damaging the bore.

Without a doubt the best I've ever seen is Deaton's Deep clean.
Here ya go:

I cleaned my 45 year old .270 Winchester bore with Hoppe's copper solvent and pushed patches till they were clean and white coming out. I have never in 45 years put any copper solvent in that barrel. Then I soaked a patch with Deadon's and pushed it down the bore. I let it sit about 5 minutes. Then I pushed a patch through and it came out deep blue, indicating lots of copper. I pushed patches (about 7) till they came out white. Then I followed with another patch wet with Deaton's and the patches came out clean almost immediately.

Then I repeated it in another equally dirty bore, my .280 Remington Mauser, with Shooter's Choice Copper Solvent. Then repeated the process with Deatons as I did on my .270. Same thing, same results. And, though Deaton's is rich in ammonia, it won't hurt your barrel because it has lubricants in it to prevent corrosion.
This stuff amazed me.

Another fan of Sweets here. It will remove any copper from your barrel quickly, just don't leave it sitting in the barrel long.

I use Sweets after every firing then make sure I get it all out. It takes 2 patches and I'm done.

I usually use Hoppes and Kroil 50/50. Leave it in the barrel all night and if there is any copper, you'll know it the next day when you put a patch through it.

Another vote for "Sweets 7.62", has worked for every application I've placed it on. Never found a reason to try any other brand.

I really like the new-ish Hoppes copper terminator. It is not an ammonia based solvent like Sweet's is, so you can leave it in the barrel without worry. It's by far the best Hoppe's copper solvent to date. It'll take all the copper out in 15 to 30 minutes. Just a note though, it does not produce the green/blue stain that you typically see from copper fouling. The patches come out a nasty brown/black.

Something with plenty of ammonia, like Sweets,or Butches Boreshine plus it can double for smelling salts, just in case you pass out when you shoot your first 5 rnd one hole group.:D

I use and trust Shooters Choice for normal cleaning.On old or badly fouled barrels,I use Sweets 7.62.The truth is that they all work,although on a side by side test using Shooters Choice and Hoppes #9,the Shooters Choice seemed to work faster and better. Lightman

Best one for removing stubborn copper?


March 13, 2011, 10:16 PM
Boretech Eliminator works well without the ammonia stench. Finish up with Hoppes #9 and Kroil 50/50.

I really like Wipe Out also, but I use the liquid Patch Out not the foam cleaner. That being said, is it the best? I have no idea, but it works very well for me and has given me no reason to switch to anything else.

If you have a bad copper fouling problem,I'd just mix up an ammonia/water solution.
I've been there,before I finally fire lapped the bad barrel (tool marks in rifling).There are many chemical gun cleaners that you can buy,some work-some don't.
But for a little of nothing you can go to your local janitorial supply and get a gallon of industrial strength ammonia (the stuff you can get at Walmart/grocery store is too watered down).

Get some rubber stoppers from the hardware store that will fit (plug) the chamber end of the barrel.
Mix up 2 parts ammonia/1 part water,plug the barrel,fill barrel with the solution,let it set for 10-15 minutes.
Pour the solution out of the barrel,remove the plug,and then clean your barrel as usual.
You should get rid of all the copper fouling in a few minutes,without scrubbing the barrel.
