How did Odysseus purge his home?

Odysseus purged his home of the suitors by first revealing his identity during a contest involving his bow, which only he could string. Once he successfully completed the challenge, he, along with his son Telemachus and loyal servants, launched a surprise attack on the suitors, killing them all. Afterward, he ordered the disloyal maids to be executed and had the house cleansed to restore order and sanctity to his home.
