There are two kinds of “exorcisms”:
1) The first kind is called a “Solemn Exorcism”:
A Solemn Exorcism can only be performed by a priest appointed by the local bishop and tehn only with the bishop’s specific permission. Canon Law sets this requirement.
2) The second kind is called a “Simple Exorcism”:
There are some simple exorcisms that can only be done by a priest or deacon, for example in the blessing of sacramentals.
Other forms of simple exorcisms can be done by laity. For example, the famous St. Michael Prayer that used to be said after Mass is a simple exorcism.
Everytime we say, “Father, cast this demon from my presence” and other such prayers we are doing a “simple exorcism.”
Some people are called to an apostolate of helping people who may have spiritual/demonological problems and harassments but are not so severely demonized as to need a solemn exorcism from the Church.
In these lesser cases of demonization, prayerful people, usually called “Deliverance Counselors” (so as not to confuse people with the solemn/simple exorcism distinction), may be laity or clergy and essentially help the demonized person to get rid of any “hooks” in their lives that demons may be hanging onto, teach the person how to pray spiritual warfare prayers and to remain close to God and His Church, and offer intercessory prayer for them.
Under current Church law, a Deliverance Counselor MAY NOT talk directly to the demons nor directly command them. Thus, instead of something like, “I rebuke you demon of anger” we must say, rather, something like, “Father in Heaven, please rebuke this demon of anger.” We must AVOID the “I” language.
When people go to help a demonized person and pray for them it is common and efficacious to fast. This is a spiritual practice that is always prudent when dealing with evil.
EXORCISM OF SALT:
2. The exorcism of salt follows: God’s creature, salt, I cast out the demon from you by the living + God, by the true + God, by the holy + God, by God who ordered you to be thrown into the water-spring by Eliseus to heal it of its barrenness.May you be a purified salt, a means of health for those who believe, a medicine for body and soul for all who make use of you.

Christ’s faithful are permitted to take holy water home withthem to sprinkle the sick, their homes, fields, vineyards, andthe like.
