What is the primary function of an ultrasonic cleaner?

An ultrasonic cleaner primarily functions to remove grease, soot, and residues from various components using high-frequency sound waves. In this cleaning process, the ultrasonic cleaner generates ultrasonic waves that create millions of microscopic bubbles in a liquid cleaning solution. When these bubbles implode, they create tiny shock waves that dislodge dirt, grease, and contaminants from surfaces, even in hard-to-reach areas.

This method is highly effective for cleaning delicate items, such as carburetors, jewelry, and precision instruments, without causing damage. The use of biodegradable cleaning solutions further enhances its effectiveness and is more environmentally friendly compared to harsh chemicals, making this cleaning method both efficient and sustainable.

The other options focus on processes that do not align with the primary functionality of an ultrasonic cleaner. For instance, polishing metal surfaces, drying components quickly, or painting and coating parts are entirely different processes that involve other tools or techniques and do not utilize the unique cleaning mechanism that ultrasonic technology provides.
