I would suggest setting your hot end to 80-90 degrees. At that temp, PLA becomes rubbery and pliable without being a melty burned out mess. You can then clip and remove the blob with care and proceed with breaking it down.
For other types of filament, you want to be just above the glass transition temperature and below the melting point. (usually it's a bit above your heated bed temperature.)
