The ultrasonic vibrations create countless invisible tiny bubbles in the water. This bubble effect generates instantaneous shockwaves, removing dirt from hard-to-reach crevices and dirt that cannot be removed with cloths, brushes, or water. 【360° All-Around Cleaning】 This small, household glasses cleaner provides 360° all-around, highly efficient cleaning.

It enhances the propagation of ultrasonic waves and increases cleaning ability. Detergent acts as a medium for ultrasonic waves. For heavy dirt, we recommend using 1 or 2 drops of neutral detergent. Note: Before using detergent, please be aware of the detergents suitable for the items you are cleaning. 【Accessory Cleaning!
