Industrial brushes are used as an abrasive for removing oxidation, paint, surface coatings, deburring operations, cleaning weld slag, and surface pre and post cleaning or preparation. Industrial brushes are typically constructed with in grip, holder or shaft feature with embedded bristles of various materials.
Brass brushes are softer and so won't scratch some grill types, such as cast iron ones. They're a softer brush, which does mean they'll wear out quicker. Steel brushes on the other hand can be used to lower cleaning times and clean hardier grills, such as stainless steel grills.
