Sea salt leaching
Put the spar in a glass of salt water with an appropriate amount of sea salt ocean (or coarse salt) and soak it for three to four hours to dissolve the magnetic field around the spar.
(1) If the spar is inlaid in a metal object to make an ornament, such as a ring, pendant, etc., please remove the spar from the metal object before immersing it in brine, otherwise it will affect the color and surface of the metal brightness.
(2) Please note that such cleaning methods may cause the contents of spar to change after cleaning.
In addition, there are the sea salt burial method, snow pile burial method, clean water purification method, aroma purification method, crystal cluster purification method, and natural cleaning.
