This powerful ultrasonic cleaner replicates the technology used by professional jewellers and dentists. Using only plain tap water, it will deep clean all sorts of objects from jewellery, spectacles and watches to CDs, DVDs, razor blades, dentures and toothbrushes. Not to be confused with cheap sonic machines that only vibrate, this one generates 43,000Hz of ultrasonic waves. These waves produce millions of minuscule pressurised bubbles that burst to gently lift dirt and grease out of the tiniest crevices.
