Removing blued metal

[J.B. Books]

I have found often times when the frame of a Parker has been blued both receiver and barrels were improperly hot blued. I am told that process will result in trouble as the bluing salts attack the rib solder and rib separation is highly likely. I also believe subjecting a CCH receiver to a hot blue salt bath anneals the metal and removes whatever hardening was made by the CCH process. Perhaps Brad Bachelder or others here with greater knowledge of the process can explain all the negatives that process can bring.
