Ultrasonic cleaning uses high-frequency sound waves to create tiny bubbles that scrub away dirt and grime. It is an effective and gentle method for cleaning delicate items such as jewelry, eyeglasses, and medical instruments.

Laser cleaning, on the other hand, uses a high-powered laser to vaporize and remove surface contaminants. It is best suited for industrial applications and is effective in removing rust, paint, and other stubborn substances.
