You can scrub with mild soapy water and then rinse with clean water. Do not use chemical degreasers. For the heavily polluted old jade, you can go to a company specializing in the production and cleaning of jade articles and use professional ultrasonic cleaning and maintenance.

Hello, I'm glad to solve your problem. According to your question, I suggest soaking in clear water for a period of time, because chemical solvents are generally soluble in water, and so is soap. Short-term contact of chemical solvents with jadeite will not cause much harm, and repeated or long-term contact will not do.

If Huang Longyu is soaked in soapy water, just clean it with clear water, so don't mind too much and don't always soak in soapy water.

Soak in clear water for a while, then brush it with a brush, then rinse it with running water and dry it. Sometimes, the evaporation of water will leave white marks on the surface of jade. This is not a trace of soap. Brush it with Panyu's wool brush for a while and it will fall off. I hope it helps you.

Soak in alkali for a while, then wash with water and dry. I heard it from someone else.

Ordinary detergent, soap and shower gel won't do any harm to jade, as long as you don't soak in it for a long time. It's absolutely no problem to take a shower with it. It is also common to take daily life with you all your life. But if you wear a jade pendant with a rope, the rope will be very old and easy to break after a long time.
