March, with its warm weather and blooming flowers, is Lei Feng Study Month.
As the “Lei Feng Memorial Day” on March 5 approaches, the Party branch of the Geotechnical Engineering Company organized a themed Party‑day event titled “Learning from Lei Feng: Volunteering to Warm Hearts.” During the event, Party members, drawing on their own experiences, upheld the spirit of hard work and simplicity, promoted paper conservation, and enthusiastically participated in a series of volunteer activities, including maintaining the orderly parking of shared bicycles and picking up litter along the roads.
At the outset of the activity, Comrade Wang Yukun, the branch’s publicity officer, set an exemplary example by voluntarily bringing his own household ultrasonic cleaner. In just a few days, he has already cleaned more than 20 pairs of glasses for colleagues in the surrounding area, using this small act of service to restore their eyewear to like-new condition and provide them with clearer, brighter vision.
The spirit of Lei Feng will never grow outdated; it is the dominant theme of a civilized society. Let us give a big thumbs-up to Comrade Wang Yukun for his proactive and kind efforts to embody the spirit of Lei Feng!
Meanwhile, we warmly invite any colleagues in need from all departments to contact Comrade Wang Yu Kun directly for eyeglass cleaning. And for our beauty‑loving ladies, you can also have your jewelry cleaned before the upcoming International Women’s Day!

[Key takeaway: Important facts to remember]
Oils, sweat, makeup, skincare products, and other residues that linger on eyeglasses or jewelry over time can cause surface corrosion or dull the luster of the pieces. Therefore, in daily use, be sure to promptly clean off any oils, sweat, or cosmetic residue.
However, if the glasses have inlaid artificial crystals or a paint coating of mediocre quality, they should not be cleaned in an ultrasonic cleaner.
In addition, beauty-conscious ladies may be wondering: Can various types of jewelry be cleaned with an ultrasonic cleaner, and what precautions should you take? Read on to find out:
Organic gemstones—such as pearls, coral, amber, beeswax, and ivory—contain organic components and generally have relatively low hardness. They are sensitive to impacts and drops, so ultrasonic cleaning should be avoided.
Gemstones: This category primarily includes colored gemstones such as rubies, sapphires, tourmalines, emeralds, and garnets. Because gemstones vary in hardness, those with higher hardness can be cleaned using an ultrasonic cleaner. However, emeralds, tourmalines, and certain stones with numerous inclusions are prone to cracking or breaking and have lower hardness; they should not be cleaned in an ultrasonic machine to avoid damage or fragmentation.
Gold and silver: This primarily refers to pure gold, 18K gold, silver, platinum, and similar materials. It is normal for gold and silver jewelry to lose its luster over time due to wear or improper storage that causes it to accumulate dirt and dust. Such pieces can be cleaned using a professional ultrasonic jewelry cleaner. For metal jewelry that will not be worn for an extended period, store it in an airtight bag to prevent oxidation and discoloration.
Jade varieties: Primarily include jadeite, Hetian jade, chalcedony, and others. The best way to care for jade is to wear it regularly; the natural oils secreted by the human body help nourish and protect the stone, giving it a richer, more lustrous appearance. Jade jewelry can be cleaned with lukewarm water and gently scrubbed with a soft brush. Avoid ultrasonic cleaning, as internal cracks may shatter under the vibrations.
Diamonds: Primarily include white diamonds, yellow diamonds, pink diamonds, and more. For prong-set or bezel-set diamond jewelry, remove the stones before placing the piece in an ultrasonic cleaner; for standard claw‑set or channel‑set designs, the jewelry can be cleaned directly in the ultrasonic cleaner.
Ultrasonic cleaners are widely recognized as an effective and highly efficient cleaning method. However, certain delicate jewelry pieces may not be suitable for ultrasonic cleaning. For valuable items that can cost tens of thousands of yuan, be sure to thoroughly research before using an ultrasonic cleaner.
