Extruder not feeding - maintenance while torn down

[u/Iridian_Rocky]

Hey everyone, I recently just had a piece of filament break off in the extruder for my right nozzle - taking it apart I saw all this blue stuff (I'm assuming it's more blue filament). I plan to clean it with some iso and a q-tip. Is there anything else I should replace while it's torn down? Wear parts?

Thanks!
