Technically speaking, NOTHING will "neutralize" the salts in corrosive priming residue because they are, like table salt, a stable compound.
Water DISSOLVES the salts and flushes them away.
Russian cleaning kits often contained a two-compartment bottle.
One side held a strong alkaline and water solution, and the other side held oil.
The alkaline and water solution removed both the primer residue and any residual oil from the bore.
