How to unclog a nozzle

What technique is everyone using for a clogged nozzle?

Acupuncture needles to start. Cold pulls if that doesn’t solve the issue. Been seeing this a lot this past week.

Well I’m back in business with PLA. Not sure if I had a clog. I could manually feed filament for days. Seemed like the filament tension on the right extruder was weak/off…not sure but thanks for your help!

Now to try some higher temp material again.
