What ultrasonic cleaning does to a casino chip
A chip’s grime is more than visible dust. Repeated handling leaves skin oils and fine debris in its grooves, edges, and other small recesses—places a quick wipe may miss. An ultrasonic cleaner reaches those tight spaces by sending high-frequency sound waves through a liquid cleaning bath.
The waves create microscopic bubbles that rapidly form and collapse, a process called cavitation. Their movement agitates the liquid against the chip’s surface, loosening residue without relying on a brush to reach every groove. The cleaner does not scrub chips with sound; it uses sound to make the bath work more vigorously at the surface.
Why the process needs care
Chips are handled as objects of value, not just as dirty plastic. Their printed or inlaid designs and materials must remain intact, so the cleaning method has to suit the particular chips and use appropriate settings and solution. Ultrasonic cleaning is useful precisely because it can clean detailed surfaces with less direct rubbing, but it is not a license to treat every chip—or every cleaning bath—the same way.
For a casino, the practical payoff is that grime can be removed from many small surfaces and crevices more consistently than by wiping each chip by hand. The same grooves that help players handle and stack chips also give residue places to collect, making the cleaning method’s reach a functional advantage.
