While ultrasonic cleaning is highly effective, it does have some limitations. The cleaning process can sometimes cause physical damage to delicate catalysts or reactor components. Additionally, not all contaminants can be removed through this method alone; some may require a combination of chemical and ultrasonic treatments. It's also worth noting that the effectiveness of ultrasonic cleaning can be influenced by factors such as the frequency of the sound waves, the temperature of the cleaning solution, and the nature of the contaminants.
