Can a wire wheel in a bench grinder be used to clean soft metal or brass parts?

Using a wire wheel in a bench grinder to clean soft metal or brass parts is not advisable due to the risk of damage and potential hazards. Wire wheels are designed primarily for use on harder materials and can cause excessive wear or deformation on softer metals like brass. The abrasive nature of the wire can create deep scratches or alter the surface finish on brass components, making them unsuitable for precise applications.

Additionally, when using a wire wheel, there is a significant risk of the wires breaking off and flying, posing safety risks to the operator and bystanders. The high-speed rotation can also generate heat, which can further deform or damage the brass components. For cleaning soft metals, it is better to use tools specifically designed for that purpose, such as plastic or nylon bristle brushes, which are gentler and less likely to compromise the material integrity.
