Make a basin of clean water, don't put other chemicals such as detergent, just clean water. Put the diamonds to be cleaned in the basin. If there is a rope, don't take it off yet. Put the whole string in and soak for a few hours.
After soaking, take out the diamond. If it is a thin rope, you can tie one end to a fixture, level the other end by hand, and brush it vertically with a wire brush. Don't brush hard back and forth, but sweep in one direction before oiling.
Extended data:
The best way to play Vajrayana is to divide the plate into three parts and brush it into seven parts. Brushing helps to brush off the patina produced when playing, because the patina will "turn off" the continuous coloring of King Kong, so it is recommended to clean the disc before playing, keep your hands clean when playing, and emphasize that the disc will be beautiful if you play clean.
Only multi-disc and multi-brush is the best maintenance method for Vajrayana Bodhi. Due to the high temperature in summer, human hands are prone to secrete oil, so the color of diamond changes quickly in summer, but a large amount of oil invades in a short time, which will inevitably lead to the closure of the surface of diamond, which will not only hinder the coloring of diamond, but also make it black.
Although summer is the most suitable season, be careful not to give your hands too much oil, let alone sweat directly. No matter how big or small a diamond is, it can't be oiled and maintained. Donkey kong will crack it anyway. Compared with small diamonds, the density is higher and the probability of cracking is very small.
