Product features

  • ULTRASONIC CLEANING - Our ultrasonic jewelry cleaner uses powerful 42,000 Hz high frequency sound waves to gently agitate and lift dirt particles from your best valuables without harming them. It excels at safely loosening caked on dirt and grime, but please understand that it is not a degreaser or tarnish remover (see our comment below about tarnish). Maximum tank capacity is 16 ounces. Plugs into 120 volt, 60 Hz (US power only) wall receptacle - no batteries needed!
  • 30 MINUTE TIMER - Easy to read display has 18 pre-set cleaning cycles from 90 seconds up to 30 minutes, with auto shut-off. Please understand that our digital ultrasonic cleaner has a 30 minute limit for two primary reasons: 1) So you can walk away and come back when the job is done, and 2) To prevent overuse and overheating from running too long. Please let the unit cool down entirely between longer runs. It is NOT designed or built to be run continuously, cycle after cycle for hours on end.
  • PERFECT FOR cleaning jewelry, dentures, Invisalign retainers, toothbrushes, body piercings, watches, eyeglasses, table-ware, baby pacifiers and other household instruments - and keeping them sparkling clean. Note that while this unit will do a great job of cleaning built-up dirt, cosmetics and skin particles from the hinges and arms of glasses, it is not meant to clean oil and grease from lens. Please do this the old fashioned way.
  • LIGHTWEIGHT, quiet and portable, our ultrasonic machine cleans up quickly, is easy to store and convenient to use. CE & RoHS Certified, safe and ecologically friendly, it's the perfect ultrasonic denture cleaner. Plus, our 30 minute digital timer makes jewelry cleaning and steeping small, personal amounts of Liposomal Vitamin C and other e-liquids a breeze. Again, this machine is designed to run a maximum of 30 min and then allowed to cool, not run continuously for hours, or for commercial use.
  • A NOTE ABOUT TARNISH - Silver or brass tarnish is a chemical reaction that requires another chemical reaction to properly remove it. Ultrasonic Cleaners do a great job of removing built-up dirt and grime from jewelry, and keeping it grime-free with regular use. Our polishing cloths remove silver tarnish because they have tarnish cleaning compounds impregnated in the cloth. But, though ultrasonic cleaners will remove some surface tarnish, they are not an effective way to remove silver tarnish.

Product description



The BlackHillsGoldSource ultrasonic cleaner uses a high frequency vibration plate beneath the stainless steel tank to create millions of microscopic waves and invisible scrubbing bubbles to gently loosen dirt and grime from your valuables without the need for harsh chemicals or vigorous brushing.


Unlike the CD2800 and CD3800 with only 5 cycles, our cleaner has 18 cleaning cycles up to 30 min. Set it and walk away knowing that your valuables will be completely clean when you return. A quick buffing with a soft cloth, or our Jewelry Care Cloth is all they need to look beautiful again.

- 16 ounce stainless steel tank, basket and watch stand, use with lid open for larger items
- Uses hot tap water for effective cleansing
- For stronger cleaning add 1 tsp of detergent, or Efferdent tablet for dentures
- Sealed tank to prevent liquid from leaking inside
- CE & RoHS Certified, safe and environmentally friendly


We want all our customers to be fully satisfied. This cleaner is designed to effectively clean jewelry, eyeglasses, dentures, scissors and other instruments. If your items have extreme tarnish build-up, it will likely need removal with a chemical tarnish remover. (See our bullet point above about tarnish)

This unit is not an industrial device meant to clean greasy parts, nor is it a commercial unit meant to be run continuously. However, it is the perfect ultrasonic cleaner for home use and with regular use will keep your jewelry and valuables clean and grime-free without any physical scrubbing. For US power only: 120v, 60 Hz.
