how to cleanse a ring of energy

i was watching the norwegian tv show studio fem - den andre siden last night and a lady on the show was ill and she gave her ring to 2 psychics on the show, gro helen tørum and lena ranehag, and they said the ring was filled with an enormous amount of energy, both bad and good, and that this might be what is causing this woman to be ill or at least compounding her illness. the ring is old and has been worn by several generations of women in this womans family so all their energy has been trapped in the ring. lena ranehag said that if you want to clean the ring of its stored energy then you put it in water with a spoonful of chunky salt (unground [grovsalt in norwegian]) and let it sit overnight.
