Brass Brush to clean 3D Printer Nozzle

• • Material: Features soft copper or brass wire bristles that clean metal surfaces without gouging or scratching the nozzle.
  • Design: Built with a compact, curved handle for a secure grip in tight spaces. 

How to Use It Safely

• Heat the Nozzle: Warm your 3D printer nozzle up (typically between 185°C and 190°C) to soften any stuck plastic. 

• Scrub Gently: Lightly brush the exterior of the nozzle, heater block, and hotend to remove residue. 

• Caution: Avoid brushing active printer wiring (like thermistor or heater cartridge wires) with a metal-bristled brush to prevent short-circuits.
