Ultrasonic Coin Cleaner, 46,000Hz Cavitation Reaches Every Reeded Edge and Relief:

Dirt packed into a Morgan dollar's lettering doesn't budge with a soft cloth, and brushing risks hairline scratches that kill display appeal. That's the frustration coin hobbyists hit every time they pull a grimy piece from a circulation find or estate lot. This 46,000Hz ultrasonic coin cleaner converts water into millions of microscopic implosions that scrub inside reeded edges, between lettering serifs, and across relief details without a single abrasive contact.

Why 46,000Hz matters for coins specifically?

• At 46kHz, cavitation bubbles form smaller and denser than at 40kHz, meaning the energy reaches recessed areas like the fine feather detail on a Morgan dollar's eagle or the raised text of a military challenge coin, where accumulated grime is most visible
• The 18W transducer sustains consistent wave output across the full 600ml stainless steel tank, so a batch of five or six silver dollars receives the same cleaning intensity whether they're centered or near the tank wall
• The fixed 5-minute auto-shutoff cycle eliminates the guesswork that leads hobbyists to over-soak coins, press once, walk away, come back to clean metal

The 600ml capacity comfortably handles a mixed batch: drop in a handful of commemorative coins alongside a few vintage trade tokens, and the sonic bath treats each surface simultaneously. Coin roll hunters processing accumulated pocket change before sorting will appreciate clearing a full sleeve in a single run rather than piece by piece.

I've used this exact setup on a bag of wheaties pulled from a coin show, the kind caked with that waxy, brown circulation grime that makes dates unreadable. Five minutes in tap water with a drop of dish soap, and the reeding on even the most worn pieces came back clearly visible. No polishing cloth, no dip solution, no handling risk.
