How to delete stuck batch? What is a good way to delete a stuck batch in Drupal 7?

It is on a production server, we are using the Background Batch module so it shows us which one it is at admin/config/system/batch/overview.

I know I can just run a query and delete that row from the DB but wondering about other cleanup I should do too.
Another approach (if you don't want to run sql-statements directly) would be Queue UI:


  
  View queues and number of items
  Developers can define meta info about queues they create and process
  Process queue with Batch API
  Process queue during cron
  Remove leases
  Delete queue
