What is the purpose of the metal cleaner prep stick?

The purpose of the metal cleaner prep stick is primarily to neutralize rust particles. This is an important step in surface preparation, especially when dealing with metal surfaces that may have oxidized or developed rust over time. By neutralizing rust, the prep stick ensures that any remaining rust does not affect the adhesion of paints or coatings applied subsequently. This action promotes longevity and durability in the final finish by ensuring a clean and stable surface.

While other functions such as cleaning glass surfaces or preparing surfaces for painting are critical in different contexts, they are not the specific function of the metal cleaner prep stick. The focus on rust neutralization highlights the importance of preparing metal surfaces to eliminate any contaminants that could compromise the integrity of subsequent applications, making it a critical tool in maintenance and restoration tasks.
