It is the prayer of Saint Michael. Prayer can be used to remove a dead spirit or a neighbor's spirit attached to an object.

The Prayer to St. Michael by Pope Leo XIII is a powerful Catholic prayer invoking the Archangel to fight evil spirits, not specifically for dead or neighbor's spirits attached to objects, but against Satan and evil forces in general, asking for protection and casting Satan into hell; it's for spiritual warfare, but objects with demonic attachments often need a priest's help for blessing/disposal, as laity should avoid complex exorcism parts, though they can use the shorter prayer for general protection. 

What the Prayer Does:

• Invokes St. Michael: Calls upon Michael as the "Prince of the Heavenly Host" to defend against wickedness. Fights Evil: Asks God to "cast into hell Satan and all the evil spirits who prowl about the world seeking the ruin of souls".

• Spiritual Warfare: Aims to strengthen believers against the devil's temptations and attacks, recognizing the reality of spiritual battles. 

Regarding Spirits on Objects:

• Objects Can Be Cursed: Yes, objects can become "cursed" through invocation of Satan or occult practices, attracting evil.

• Different Approaches:

  • For Laity: Sprinkle the object with holy water, pray for God to lift curses, and then destroy, burn, or bury it.

  • For Serious Cases: If an object is deeply cursed or has attached demons, a priest (an authorized exorcist) should handle it due to potential for retaliation against the person trying to destroy it.

• Not for Lay Exorcism: The longer, more intense exorcism prayer composed by Pope Leo XIII (found in the Roman Ritual) contains parts meant only for ordained clergy, though the shorter, widely known prayer is for all faithful. 

In Summary: The prayer is for spiritual protection from evil in general. If you suspect a spirit or attachment on an object, use holy water and destroy it if possible, but for serious infestations or curses, seek a Catholic priest.
