Most copper solvents are ammonia based and etch or dissolve copper fouling??from the bore.?? However,??ammonia??has several drawbacks.????

First, it is very??toxic. Fumes in a non?€?ventilated workroom have sent many gun enthusiasts and armorers to the hospital.

Second, it is very corrosive not only to copper, but in many cases steel, aluminum and other alloys. You probably know someone that has left an ammonia copper solvent in??the barrel overnight only to come back to a pitted barrel. Ammonia can also form??hydrophilic??ammonia crystals in the bore that??
attract water and can cause rusting, pitting and microscopic stress fractures over time.

Lastly, traditional copper solvents are slow-acting. The actual 24 hour etch rate for even the strongest ammonia copper solvent is less than 1% total copper dissolved.??Copper fouling is dissolved from the top down, only affecting the metal that the copper solvent is able come in??contact with. Carbon fouling blocks and slows this process.

A Chemistry Breakthrough

Chemists at??M?€?Pro7??studied the bonds between the copper and carbon fouling and found that the layers attach to bore steel differently than previously thought??
in the industry (see diagram right). As a result, they developed a non-toxic??
chemistry that not only succeeds in removing copper fouling faster, but more thoroughly than traditional methods.????M?€?Pro7 Copper Remover??does not etch copper fouling??in the same way as ammonia based??chemistries.

M-Pro7 Copper Remover's??technology attacks the edges of the copper fouling in a barrel and penetrates underneath the layers. This methodology is lifting and removing copper fouling??entire??layers at a time, rather than etching a small portion of the copper.?? Consequently, the copper fouling comes out as a copper colored sludge. The chemists also addressed the other limitations of traditional??copper fouling removal. The new??M?€?Pro7 Copper Remover??technology is odorless and??non?€?hazardous for safe use. The new technology is also completely safe on bore steel and leaves no??hydrophilic crystals. If allowed to dry, the??Copper Remover??leaves a protective film that is very effective for short?€?term corrosion protection.

To the Last Copper Fouling Layer

Based on the chemists?€? findings, it was determined that the most thorough removal of copper fouling requires a system based approach.??

M?€?Pro7 Gun Cleaner??is used first to remove carbon fouling. As mentioned before, carbon fouling slows the etching process??(whether you are using??
M?€?Pro7??or??any other copper remover). Then??M?€?Pro7 Copper Remover??is used to start penetrating underneath and lifting copper fouling in barrel. Once the Copper Remover??removes the first layer of??copper, a layer of carbon is revealed again slowing the etching/penetration process. Switching back and forth between??the two products a few times will??facillitate??even the most stubborn copper fouling removal.??

M?€?Pro7 Gun Cleaner??should be used at the end??of the cleaning process to condition the bore to help repel future??copper and carbon fouling. Use??M?€?Pro7??
Gun Oil LPX
??to lubricate and protect against corrosion.

Copper Fouling Indicator

One??perceived??drawback to??M?€?Pro7 Copper Remover??is that there is no visual??
indicator that the copper fouling??is being removed. Ammonia based products turn the copper fouling blue so you can??see the results on the patch. Unfortunately, this visual indicator can be very misleading. As??mentioned before, copper and carbon fouling are deposited in the bore in layers. Most ammonia based products have very little effect on carbon. If the carbon layer is covering the copper layer, the patch may come out completely white giving the false appearance that the bore is completely free of fouling when in??fact it may contain a great deal of copper fouling. The only way of truly verifying that the bore is free of copper fouling is visual inspection. A bore scope is the best way to insure that your bore is carbon and copper fouling free.
