When the jade pieces are in hand, first soak them in normal temperature water for 2-3 hours (to soften the surface attachments), then brush them with a toothbrush, then put them in hot water (about 70 or 80 degrees in new jade), soak them in hot water. Slowly and naturally cool with jade, usually I will put it in a heat-insulating place where air does not flow, so that the hot water will slowly cool down. This also allows the pores of the jade to be fully relaxed, and the internal dirt is spit clean. This is done for about 3 cycles, then once every 3 months to half a year, and once in the summer for about 1 to 2 months.
Also, always remember not to put the jade on the face and nose to smear oil (often seen), the oil is not the so-called jade nourishing liquid, but it is counterproductive to seal the jade door (capillary pores) to make the plate The jade gloss that came out was very stuffy. There is no need to use a bristle brush, because the patina that comes out of the brush feels like a thief. It is recommended to use a soft "white cotton" long towel tray, but it is not suitable to use a dyed cloth or a hard cloth of chemical fiber.
After playing in the summer for 1 week (2-3 weeks in winter), use warm water (about 40 degrees) every night to bathe, soak for a while and then brush it clean. Please avoid direct contact with soap. Just keep the jade pieces clean. If it is convenient, it can be washed frequently. It is well known that sweat contains salt, volatile fatty acid and urea. The jade pieces are exposed to too much sweat, and they are not cleaned up immediately after wearing. The jade pieces will be eroded and the outer layer will be damaged, which will affect the original gloss. Especially white jade, more avoid sweat and grease. If white jade is too much contact with sweat, it will easily turn pale yellow, no longer pure white as fat.
