This 6L digital ultrasonic cleaner has a powerful cleaning efficiency! With a power of 400W, it can easily remove not only the dirt accumulated on jewelry for years but also the stubborn stains in the gaps of glasses. In the past, when cleaning jewelry and glasses, I had to be very careful and use various tools, but it was still difficult to clean them thoroughly. Now, just put them into the cleaner, and in just a few minutes, they will become brand - new. It's really convenient and greatly saves my cleaning time and energy.
