Never use chemical cleaners on jade. Just a few drops of mild liquid soap in a medium-size bowl of water . You should have a few suds but not overly soapy water.
Dip a soft cloth into the soapy water and gently wipe your jade until it is clean. Do not scrub at it, as scrubbing can scratch the surface. Also, take care to avoid immersing it in the soapy water. Dip the cloth in clean water and remove any suds from the jewelry.
Dry your jade off with a different soft cloth. Make sure to remove all traces of soapy water but do not immerse the jade to rinse it. Finally, polish your jade with a polishing cloth.
Touching jade increases the luster and richness of the stone, so don’t feel like you have to clean your jade jewelry every time you wear it. Instead, wipe it with a soft cloth after wearing it and clean it only when you notice soiling. Also, store jade in a jewelry bag or in its own compartment of your jewelry box.
Do not use an ultrasonic cleaner or a steam cleaner. The extreme heat can damage jade.
Remove jade jewelry before swimming; chlorine in hot tubs and pools is very harmful to jade.
