Blessed salt is an instrument of grace to preserve one from the corruption of evil occurring as sin, sickness, demonic influence, etc.
As in the case of all sacramentals, its power comes not from the sign itself, but by means of the Church's official (liturgical, not private) prayer of blessing -- a power the Church derives from Christ Himself. (see Matt. 16:19 and 18:18).
As the Vatican II document on the Liturgy states, both Sacraments and sacramentals sanctify us, not of themselves, but by power flowing from the redemptive act of Jesus, elicited by the Church's intercession to be directed through those external signs and elements. Hence sacramentals like blessed salt, holy water, medals, etc., are not to be used superstitiously as having self-contained power, but as 'focus points' funneling one's faith toward Jesus, just as a flag is used as a focus point of patriotism, or as handkerchiefs were used to focus faith for healing and deliverance (Acts 19:12).
Thus, used non-superstitiously, modest amounts of blessed salt may be sprinkled in one's bedroom, or across thresholds to prevent burglary, in cars for safety, etc. A few grains of blessed salt in drinking water or used in cooking or as food seasoning often bring astonishing spiritual and physical benefits. As with the use of Sacraments, much depends on the faith and devotion of the person using salt or any sacramental. This faith must be Jesus-centered, as was the faith of the blind man in John 9; he had faith in Jesus, not in the mud and spittle used by Jesus to heal him.
Blessed salt is not a new sacramental, but the Holy Spirit seems to be leading many to a new interest in its remarkable power as an instrument of grace and healing. Any amount of salt may be presented to a priest for his blessing using the following official prayer from the Roman Ritual:
"Almighty God, we ask you to bless this salt, as once you blessed the salt scattered over the water by the prophet Elisha. Wherever this salt (and water) is sprinkled, drive away the power of evil, and protect us always by the presence of your Holy Spirit. Grant this through Christ our Lord. Amen"
If you are interested in getting blessed salt, print this information out and present the blessing prayer to your parish priest. Ask him to bless the salt for you using the official prayer from the Roman Ritual printed above.
