It is better to degauss the crystal with royal salt, but pay attention to whether there is a certificate when buying to avoid buying fake royal salt. Now the so-called degaussing of crystal clusters and crystal holes are all hyped by Jiangsu Crystal Store. In fact, no one has any degaussing function just to promote sales. There are also so-called moonlight degaussing, refrigerator degaussing and fumigation degaussing, which are promoted by many shops selling synthetic crystals. Because synthetic crystals are afraid of using defensive salts, they are all making up some unrealistic degaussing methods. It is said that these fabricators are really ignorant, and degaussing refrigerators is just like degaussing pig's trotters.
