What is the corrosion of sweat marks on fingerprints?

2025-07-28View Original

Thread Content

Corrosion is likely to occur when the workpiece comes into contact with human hands. Fingerprints left on the surfaces of new machine tools and metal workpieces during handling can cause corrosion. This situation is common in people with acidic skin, as well as in workpieces with a high surface smoothness. Using an ink neutralizer can prevent similar ink corrosion.
