Depending on whether surfaces, edges, threads, drilled holes etc. shall be worked, there are different application for different brush types. Depending on the degree of rust, different bristles are used:   

  • crimped steel wire is sufficient for light rust. 
  • Knotted steel wire or corded wires are used for massive rust. 
  • crimped, plastic-coated steel wire is adequate for on-point derusting of a defined place.
