Degritter is a start-up company from Estonia who have developed a technologically advanced ultrasonic record cleaning machine. Degritter uses ultrasonic cleaning in a water tank followed by a separate drying cycle to provide superb cleaning effect. To create the best ultrasonic cleaning system. Degritter experimented with different frequencies, virtually simulated the energy distributions and made multiple physical set-ups to measure the energy levels. They built their own custom ultrasonic amplifier to power the system and spent long hours under a high resolution microscope to assess the safety of the device.
