So are car engines have carbon residue ? So I bought some GUMOUT "Concentrated Fuel injector Cleaner" will this do the job with a follow up of Sweets for the copper?

Don't know why it wouldn't work. BUT as long as a bottle of normal rifle cleaner seems to sit on my bench I figure it's cheap enough and designed for the job.

I still use Ed's Red. Packy

With the amount of money you have in the gun, cleaning solvent is cheap. Why cut corners on your good guns?

1 can of Top Engine Cleaner, 8 oz. of Marvel Mystry Oil and 2 oz. of hydrogen peroxide.
And if you want to clean and get the copper then add 4 to 6 oz. of 28% ammonia.

Make some "Blue Goop"...A quart jar of 25% comm. Ammonia, a cup of Hydrogen Peroxide and toss in a copper penny or jacketed bullet to turn it blue...Benchresters been using it for years..don't leave it in the barrel too long and oil the barrel after cleaning...Soap and hot water will clean powder residue better thatn anythng else, again oil it after cleaning.

I was once told to add Hydrogen peroxide to a barrel when I have Sweets in it. So I did that and it turned into foam. I let it soak for 10 minutes cleaned it with Hoppes,and there still was some copper in it. So another soaking with sweets only and patch came out blue. So just what does the Hydrogen Peroxide suppose to do?

Blue goop - what's the point of adding copper with a penny ? It's copper that you want to remove so the penny just weakens the solution.

The Hydrogen Peroxide just acts as an oxidizer.

So that means the Hydrogen Peroxide helps sweets take electrons from the copper in the barrel? Is that what the blue stuff on a patch is ? Copper that has been depleted of a few electrons?

Since my Grandson and I shoot benchrest and also hunt, we use a lot of cleaning solvent. I make a gallon at a time. I use 2 bottles of Sweets, I can of Kroil, and the rest is GM Top Engine cleaner. Fortunetly I have 35-40 cans of GM Top Engine Cleaner left as it has been discontinued. I do have a borescope and can check my cleaning method.

Oh know GM Engine Top cleaner has been discontinued? What about brake cleaning spray? What other things can I purchase at local Auto parts store??????

BraKlean and Carb Cleaners can melt some plastics. Just ask the grip panels on my Ruger Mk II pistol...

Ed's Red (Google for the recipe) makes a fantastic CLP - cost per gallon is $12! I follow it up with a blast of Non-chlorinated carb cleaner (generic brand from Walmart is $1.50) down the rails to blast away the sludge that the Ed's Red turned the carbon into. Finally a dose of grease.

My gunsmith told me to use GM Top Engine Cleaner, too. It's cheap and it works great. It even smells like the bore cleaners for which you pay an arm and a leg. And now you tell me it's discontinued? Why? Did it work so well for guns that someone decided we couldn't have it anymore?

I should think there is an alternative somewhere. What does Ford or Chrysler use to clean the tops of their engines? We'll go there...

I blinked first I've since paid and arm and a leg for the correct stuff. Hey been using KG12,that's great stuff,perhaps the best there is

With all the concoctions on the shelves, if someone is on a really tight budget just plain old soap and hot water works pretty darn good too. Maybe not for copper, but pretty much everything else.

Ultra sonic cleaner makes my life easier when I shoot a lot.

All those chemistry classes were a waste of time, I could have come here to learn about covalent bonds, etc.

Hoppe's No. 9 in quart bottles. And if some babe puts a little behind her ear, I'll promise her the mooon.

If you spray a cleaner then Carborator Cleaner and/or Break Cleaner will work.
I used ED's Red, home made mixture.
Go to Google and type in Ed's Red and see what you get.

Hydrogen peroxide oxidizes the copper, and ammonia disolves the oxide. Ammonia doesn't do that much to clean copper. If you don't believe it fill a shot glass full of CR-10 or even 20% janitorial ammonia then throw a few new clean brand new bullets in and leave it to soak over-night. In the morning you can wipe them off and put them back in the box, and pour the CR-10 back in the bottle. It doesn't do shit to clean copper.
The down-side to the peroxide is that it will also oxidize steel. That isn't good.

welllllll, maybe not exactly?

iron is more electropositive than copper, so in an oxidizing environment, the iron will oxidize first. not what I want to happen in my barrels. furthermore, the outers foul out system makes the barrel negative, or reducing, which is the exact opposite of oxidizing. make the barrel the oxidizing electrode in a reaction and it will rust immediately - iron oxide.

the blue color comes from the copper complexing with ammonia. it is ligand bonding, not covalent bonding. copper forms ligand complexes with ammonia much more readily than iron does, which is why ammonia is such a popular bore cleaner. ammonia also complexes well with nickel, forming a green color.

I bought the GM top engine cleaner two weeks ago at a local Napa store. It now comes in a plastic 2 chamber bottle. Same part number as when it came in the tin can. Cost $13 now.

Ed's Red isn't any good for cleaning copper fouling. It's an excellent cleaner for cast shooters. It's one part ATF, Kerosene, and Mineral oil. If you want it to clean plastic fouling out of shotguns, etc., add one part Acetone. I've been using it for years in my cast bullet shooting cleaning. Beware the Acetone will attack plastics and some stock finishes.
