Hi Luis, You can run the remove unused authorities script. I believe it's located in ../koha/bin/migration_tools/remove_unused_authorities.pl with a package install. We have this set up as a cron job, run once a month.
=== This script removes authority records that do not have any biblio records attached to them. If the --aut option is supplied, only authority records of that particular type will be checked for usage. --aut can be repeated. If --aut is not supplied, all authority records will be checked. Use --test to perform a test run. This script does not ask the operator to confirm the deletion of each authority record. parameters --aut|authtypecode TYPE the list of authtypes to check --test or -t test mode, don't delete really, just count --help or -h show this message. === Hope this helps!
