Failure to neutralize these residues can result in accelerated corrosion, negating the benefits of the initial rust removal efforts. This is particularly pertinent after chemical treatments where the firearm surface may retain traces of the reactive agent.
The connection between neutralization and corrosion prevention is direct and consequential. For example, consider a firearm treated with phosphoric acid to convert rust. While the phosphoric acid converts iron oxide into a stable phosphate coating, residual acid left on the surface will continue to corrode the metal. Neutralization, typically achieved with a mild alkaline solution like baking soda and water, counteracts the residual acid, preventing further corrosion. Without this step, the firearm is left vulnerable, and the rust removal procedure becomes counterproductive. Similarly, alkaline cleaners, while effective at removing rust, can leave residues that attract moisture, promoting corrosion. Neutralization in this case involves rinsing with deionized water and applying a corrosion inhibitor.
In summary, neutralization is not a supplementary step but an essential component of comprehensive rust removal from firearms. It addresses the potential long-term consequences of corrosive residues, ensuring the firearm remains protected against future corrosion.
