Flashforge Dreamer (NX) - Cleaning Print Head When Using PETG Filament

This video shows how I cleaned the print head after having extrusion problems while printing PETG filament.
PETG has a higher melting point than PLA filament and is more difficult to remove completely from the print head.

I try:
1) The cleaning rod that comes with the printer
2) Cleaning filament
3) 0.4mm needles
4) A "Cold Pull"
