When first blocked try a cold pull, nozzle cleaning needles are also readily available on Amazon for using on a hot nozzle, often in a package with several spare nozzles. If you are getting blocked nozzles perhaps check for extruder filament grinding, often caused by a deterioration of the end of the PTFE tube where it butts against the nozzle.
