Cleaning jewelry: Brilliant shine with ultrasound
Jewelry is much more than an accessory. Whether it's a wedding ring, necklace, or bracelet, it represents memories, value, and personality. But even the most beautiful pieces lose their shine over time: Skin oils, cosmetics, dust, and dirt particles build up, dulling jewelry and causing long-term damage. With the right care and an ultrasonic cleaner, you can restore the shine of your favorite pieces – gently, hygienically, and professionally, just like at a jeweler's.
Why regular jewelry care is so important
-
Avoid loss of shine: Deposits prevent light reflection, making jewelry appear dull.
-
Prevent material damage: Residues can attack precious metals and settings.
-
Ensure hygiene: Jewelry collects bacteria and germs that can cause skin irritation.
-
Maintain value: Proper cleaning is crucial, especially for valuable jewelry, to preserve its material and emotional value.
